Analysis of solvent classification and properties in coatings
First, what is a solvent?
Any kind of liquid with the ability to dissolve other substances, and can generate a homogeneous solution, can be called “solvent”, water is also a solvent, only the object of dissolution and organic solvents are different; and organic solvents narrowly speaking is the liquid to dissolve the solid, to become the other structure, and no change into other new substances of the liquid.
Currently ink and paint solvent, generally volatile organic solvents; its main function is to control and regulate the viscosity of the coating, that is, in the dissolution of the formation of the coating film to give the appropriate viscosity. Solvent selection and adding the right amount or not, will affect the fluidity of the coating, drying speed.
Second, the nature of the solvent
1. solvency
Dissolving power refers to the solvent can dissolve the film-forming substances dispersed ability to make the film-forming substances uniformly dispersed in the solvent and the formation of a stable solution. Solvent solvency and film-forming substances related to the type; the rules of solvency is a polar resin needs polar solvents (such as alcohols, esters, ketones); non-polar aliphatic hydrocarbons can be dissolved coating oil (such as oil varnish, long oil alkyd resin). Therefore, the correct choice of solvent must understand the corresponding solvent species with each film-forming substances, otherwise it will cause turbidity, precipitation, precipitation, loss of light or even scrap.
2. The role of solvents
The main function of the solvent is to dissolve and dilute solid or high-viscosity film-forming substances (resins and oils), so that it can be easily coated on the surface of the workpiece, and to make it level and form a flat continuous uniform film.
The varieties and quantities of solvents largely determine many of the properties of liquid coatings, such as viscosity, drying speed, toxicity, odour, flammability, explosiveness, etc.; the need for careful selection and deployment of solvents.
3. Solvent evaporation rate
Volatilisation speed is the speed at which the solvent evaporates from the coating into the air. It determines the length of time the coating is in a fluid state. Affect the solvent evaporation rate of many factors, the biggest relationship is the boiling point of the solvent. Solvent evaporation rate and the boiling point of the solvent is roughly proportional.
Third, the classification of solvents
Solvents can be generally on its boiling point, polarity, chemical composition, use, solvency and evaporation rate to classification.
1. Classification by boiling point
Boiling point below 100 ℃ is called “low boiling point solvents”, such as acetone, ethanol, ethyl acetate, benzene, methyl ethyl ketone, etc.; help to prevent the wet coating of the flow of hanging, its volatile fast, easy to dry, low viscosity, usually with a volatile odour.
Boiling point of 100 ℃ ~ 150 ℃ between the so-called “boiling point solvents”, such as toluene, xylene, butyl acetate, methyl isobutyl ketone, butyl ester, etc., and its volatility is moderate, in the coating following the low boiling point of the solvent volatilisation, is conducive to the formation of the coating of the leveling of the dense paint film, in the industry is widely used.
Boiling point of 150 ℃ ~ 200 ℃ such as cyclohexanone, amyl acetate, glycol butyl ether, cyclohexanol, turpentine and other so-called “high-boiling solvents”, volatilisation is slower, in the coating of the last volatilisation, not only is conducive to the levelling, but also to prevent volatile paint due to humidity and low temperatures caused by whitening of the coating and so on.
Plasticiser: this solvent is less used to dissolve on, more for additives, such as plasticisers, softeners, etc., boiling point above 300 ℃, almost no evaporation, used to change the hardness of the polymer, can not be added, so as not to dry.
2. Classification by chemical composition
Hydrocarbon solvents: such as aliphatic and aromatic-based, aliphatic can be divided into straight-chain paraffinic hydrocarbons; aromatic solvents are benzene as the core, benzene, toluene, xylene is widely used.
Oxygen-containing solvents: such solvents due to the carbon and hydrogen outside the two elements, containing oxygen, so the solvency is stronger, such as alcohol, acetone, ethyl acetate and so on.
3. Classification by polarity
Is classified according to whether it conducts electricity, the so-called conductive known as “polar solvents”; for example: alcohols, esters, ketones, etc., and other conductivity has a strong and weak size difference.
4. Classified by evaporation speed (this classification is based on butyl acetate (BAC), compared at room temperature)
Fast-drying type: more than 3 times faster than BAC;
Medium dry solvent: more than 1.5 times faster than BAC;
Slow-drying solvents: those whose evaporation rate is between that of butyl acetate (BAC) and pentanol;
Very slow drying solvent: such as cyclohexanone, diethylene glycol ether, etc..
5. According to the solvency classification
True solvent: also known as “active solvent”, for a specific resin can be dissolved alone; for example, nitrocellulose can really dissolve the ester, ether, ketone solvents.
Co-solvent: also known as “latent solvent”, when used alone without the ability to actually dissolve, but when used in conjunction with the real solvent can increase the solvency of the solvent; such as alcohols.
Diluent: no real solute solubility itself, but in some solvents to adjust the viscosity in order to facilitate the operation of the person; general coating paint diluent used is called “banana water” (Tiana water), such as benzene.
General mixed solvents in the true solvent, additives and diluent ratio of about 35:15:50, while the proportion of low, medium and high boiling point solvents is about 25:65:10.
Table of the order of polarity of common solvents
Strong polarity solvent:
Methanol〉Ethanol〉Isopropanol
Medium polarity solvent:
Ethyl cyanide〉Ethyl acetate〉Chloroform〉Dichloromethane〉Ether〉Toluene
Non-polar solvents:
Cyclohexane, petroleum ether, hexane, pentane
The order of polarity of a single solvent is:
Petroleum ether (small) → cyclohexane → carbon tetrachloride → trichloroethylene → benzene → toluene → dichloromethane → chloroform → ethyl ether → ethyl acetate → methyl acetate → acetone → n-propanol → methanol → pyridine → acetic acid (large)
Order of polarity of mixed solvents:
Benzene: Chloroform (1+1) → Cyclohexane: Ethyl Acetate (8+2) → Chloroform: Acetone (95+5) → Benzene: Acetone (9+1) → Benzene: Ethyl Acetate (8+2) → Chloroform: Ethyl Ether (9+1) → Benzene: Methanol (95+5) → Benzene: Ethyl Ether (6+4) → Cyclohexane: Ethyl Acetate (1+1) → Chloroform: Ether (8+2) → Chloroform: Methanol (99+1) → Benzene.

Note: Benzene:methanol (95+5) means 95 volume of benzene mixed with 5 volume of methanol to form a mixed solvent!
Commonly used solvent mixtures:
Ethyl acetate/hexane: commonly used in concentrations of 0-30%. However, it is sometimes difficult to remove the solvent completely on a rotary evaporator.
Ether/ Pentane system: 0~40% concentration is more commonly used. Very easy to remove on rotary evaporator.
Ethanol/hexane or pentane: 5-30% is preferred for strong polar compounds.
Dichloromethane/ Hexane or Pentane: 5~30% can be considered when other solvent mixtures fail.

Types and properties of common solvents
1. Aliphatic hydrocarbon solvents
The chemical composition of aliphatic hydrocarbon solvents is mainly chain hydrocarbons, is a product of petroleum fractionation.
① petroleum ether is a low-boiling fraction of petroleum, a mixture of low-grade alkanes; now less used in paint.
② 200 # paint solvent oil is a mixture of alkanes, olefins, cycloalkanes and a small amount of aromatic hydrocarbons containing C4 ~ C11, the main components are pentane, hexane, heptane and octane. Direct distillation of crude oil from the production of straight-run gasoline is basically free of olefins, through the cracking of gasoline contains a considerable amount of olefins, as a solvent for the use of gasoline required to be free of cracked fractions and tetraethyl lead.
200# paint solvent oil is one kind of solvent gasoline, its boiling range is 145℃～200℃. Because the beginning is used instead of turpentine, so historically known as “turpentine”, in foreign countries called “mineral spirits.
2. Aromatic hydrocarbon solvents
Aromatic hydrocarbon solvents is currently the largest industrial use of a, according to the source of coked aromatics and petroleum aromatics are divided into two categories. Coked aromatics are obtained by fractionation of coal tar, and petroleum aromatics are obtained by distillation of petroleum products through platinum reforming oil, catalytic cracking oil and toluene gasification oil.
Benzene (BENZE) is miscible with most organic solvents. The main use in the paint and butyl acetate, acetone and butanol with the use of nitro paint as a diluent.
② Toluene (TOL) can be mixed with many organic solvents. The volatility is 3 times faster than that of xylene, so it is rarely used as a solvent and is mainly one of the components of mixed solvents.
③ Xylene (XL) commonly used word is adjacent, between, para-xylene three isomers of any one of them are not suitable for use alone as a solvent in coatings. Industrial mixed xylene is a colourless transparent liquid with the characteristic odour of aromatic hydrocarbons and sometimes emits a faint fluorescent light.
Anhydrous xylene is commonly used in the paint industry. It is insoluble in water and miscible with ethanol, ether, aromatic and aliphatic hydrocarbon solvents. It has strong solvency and moderate evaporation rate, and is one of the most used solvents at present.
(iii) Solvent naphtha is colourless or light yellow liquid, which is a mixture of coked aromatic hydrocarbons obtained by fractionation of coal tar light oil. Boiling range of 120 ℃ ~ 200 ℃, mainly toluene, xylene isomers, ethylbenzene, isopropylbenzene and other components.
④ High-boiling aromatic hydrocarbon solvents, petroleum aromatic hydrocarbons, heavy aromatics is extracted after the C8 fraction, the remaining C9, C10 and other high-boiling fractions of the mixture. It began to say “heavy aromatic hydrocarbons” as a substitute for xylene, after the discovery of the special value, and further divided into different fractions, can extend the boiling point, solubility and volatility of the speed of the best, is China’s coatings industry to use more imported products.
Its advantages are mainly aromatic hydrocarbons, in the film drying, solvent volatilisation of the whole process has a high degree of solvency; so that the film without crust phenomenon, and has a gloss; can be mixed with xylene to improve the rate of volatilisation; can also be mixed with the No. 200 solvent gasoline, to improve the solvency; flash point is higher, safer.
3.Terpene solvent
Derived from pine tree, is an earlier solvent; commonly used turpentine, dipentene.
4.Alcohol solvents
Alcohols, ketones, esters, alcohol ether solvents are often referred to as “oxygenated solvents”; that is, solvents containing oxygen atoms in the molecule. Wide range of solubility, can dissolve most of the resin, often mixed with other solvents.
Ethanol (ETHONL), commonly known as “alcohol”, often mixed with other solvents, as a diluent.
Isopropyl alcohol (IBA), solvency and volatility rate and ethanol close to the strong smell; mainly used for nitrocellulose and acetate fibre coating co-solvent.
n-Butanol (NBA) is a colourless transparent liquid with special aromatic odour, miscible with alcohol, ether, benzene and other organic solvents. The mixed solvent of n-butanol and xylene is widely used in amino baking paint and epoxy resin paint; n-butanol is the co-solvent of nitrofibre resin, due to its high boiling point and slow evaporation, so it has “anti-white effect”; its disadvantage is that the viscosity is larger.
5. Ketone solvent
Ketone solvent is another type of oxygenated solvent.
① Acetone (ACT), is a low boiling point, fast evaporation rate of strong solvents, is a good solvent for volatile coatings. Because of its cooling effect of rapid evaporation, can cause condensation of water vapour in the air on the surface of the film, which leads to the surface of the film frost white, it is often used together with its anti-white effect of low volatility alcohols and alcohols and ethers solvents.
② methyl ethyl ketone (MEK) – solvency and acetone, but the rate of evaporation is slower, is nitrocellulose, acrylic resin, vinyl resin, epoxy resins, polyurethane resins commonly used in one of the solvents.
Methyl isobutyl ketone (MIBK) is slower than methyl ethyl ketone volatilisation, has strong solvency power and good performance, often mixed with other solvents.
Cyclohexanone (CHK) is a strong solvent, slow evaporation, excellent solvency for a variety of resins, mainly used in polyurethane, epoxy resin, vinyl resin coatings; it can improve the adhesion of the paint film, and make the film smooth and beautiful.
⑤ Isophorone (IP)-is a light yellow liquid with camphor-like odour, with high boiling point, low hygroscopicity, slow volatility and good solubility, miscible with most organic solvents and many kinds of nitrocellulose coatings.
(6) Diacetone Alcohol – is a colourless and odourless transparent liquid, commonly used to formulate electrostatic diluents.
6. Ester solvents
Ester solvents are also a kind of oxygenated solvents. Most of the ester solvents commonly used in paints are acetate, but also a small amount of organic acid esters. This kind of solvent CAC is the extremely important solvent of PU coating (PU slow drying water).
① ethyl acetate (EAC) is a colourless transparent liquid, with a fruity aroma, miscible with most organic solvents, can dissolve vegetable oils, glycerol rosin esters, nitrocellulose, vinyl chloride resins and polystyrene resins, etc., can be used as a solvent for nitrocellulose, ethylcellulose, polyacrylic acid resin and polyurethane resins in the paint.
② n-butyl acetate (BAC) – a colorless liquid with a fruity smell, insoluble in water, but also difficult to hydrolyze, miscible with alcohols, ethers and other general organic solvents; vegetable oils, rosin esters of glycerin, polyvinyl acetate resins, polyacrylic resins, chlorinated rubber and so on have a good solvency, is nitrocellulose coatings, polyacrylate coatings, chlorinated rubber coatings, polyurethane coatings, commonly used solvents. It is a common solvent in nitrocellulose coating, polyacrylate coating, chlorinated rubber coating and polyurethane coating.
③ Isobutyl acetate (IBAC) – similar in nature to BAC, but with a lower flash point of 17.8℃.
④ High-carbon alcohol acetate – is hexyl acetate, heptyl acetate, acetate, acetate of three high-carbon alcohol acetate, as a high-boiling point ester solvent, it has a higher solvency of oxygen-containing solvents, but also maintains the nature of hydrocarbon solvents.
Existing hexyl acetate for moisture-sensitive air-drying coatings, its slower evaporation rate can effectively reduce the film’s “whitening” tendency, and at the same time, it has a certain volatility, can be fast-drying, in the nitrocellulose coatings, two-component polyurethane coatings and volatile acrylic resin paints have a unique advantage.
7. Alcohol ether and ether ester solvents
① Glycol ether – also known as glycol ether or ethanol solvent fibre, is a colourless liquid, has a mild aroma belongs to the “highly toxic” category. Can be miscible with water, alcohol, ether, acetone and other solvents, is a good co-solvent for water-based coatings.
② glycol butyl ether, also known as glycol butyl ether or butyl solvent fibre, a colourless liquid, the only aroma; can be dissolved in acetone, benzene, ethyl ether, methanol and other organic solvents, nitrocellulose coatings are good solvents, and can play a role in preventing whitening. Used in most paints, it can play the role of anti-wrinkle, anti-fog, improve film fluidity and gloss; it is a good co-solvent for water-based paint.
(iii) Ethylene glycol ethyl ether acetate – also known as glycol ethyl ether acetate, ethyl solvent acetate or acetic acid – 2-ethoxyethyl ester, is a colourless liquid, slightly aromatic. Because of its molecular structure contains ether and ester structure, can be mixed with a variety of solvents, has a high solvency, can dissolve grease, rosin, chlorinated rubber, nitrocellulose, alkyd resin, phenolic resin and so on a variety of coating products. Its volatilisation speed is slow, which is conducive to the levelling of the coating film, making the coating film even and improving the glossy adhesion; it is often used as a co-solvent in water-based coatings.
Propylene glycol ether solvent – including propylene glycol methyl ether, propylene glycol ethyl ether, propylene glycol butyl ether and its esters. Its chemical properties and glycol ether solvents are similar, but the toxicity is much lower, foreign countries are gradually used to replace glycol ether solvents.
Propylene glycol ether solvents have strong solvency ability and slow volatility, which can improve the levelling, gloss and fullness of the coating film, and overcome the common pathologies of some coating films, and are good solvents for nitrocellulose coatings, amino-alkyd coatings, acrylic coatings and epoxy coatings; they are also the best co-solvents for waterborne coatings and film-forming auxiliaries because of the possibility of miscible solubility in any proportion with water.
⑤ Diethylene glycol ether solvent – this kind of solvent generally has a high boiling point, often added in the paint, used to improve the brushability, levelling and film adhesion; seldom used for secondary viscosity adjustment and dilution, not introduced here.

Summary
Through the above analysis, it can be concluded that: solvent as an important component of paint, has an irreplaceable role in coating film, the choice and whether the amount of addition is reasonable will directly affect the quality of the coating film.
At present, there is no universal quantitative experiment in the domestic and international research of furniture coating because of the large differences in the environment and substrate of coating; however, the following principles should be followed:
The design of the coating process should pay attention in advance to the viscosity of the solution in the known concentration, to prevent the addition of resin to a certain amount when the resin precipitation phenomenon; that is, to determine the dilution limit.
The volatility of the solvent will affect the evaporation rate, the evaporation rate will affect the fluidity of the resin and levelling, that is, affecting the quality of the film; its relationship with the way of coating is very great, in which the evaporation rate of spraying is the largest, followed by brushing, drenching, dip coating in order of decreasing; therefore, should be added according to the way of coating to select, in general, the wide boiling range of solvents to adapt to the wider range.
Solvent vapour has been identified as one of the sources of air pollutants, but because it is not yet possible to completely replace, should be based on the size of the solvent toxicity, in the solvency, the role of the differences are not too small in the case of trying to use less toxic solvents (especially diluents used for cleaning); the general toxicity of the order from the largest to the smallest: the first category, benzene, chlorinated alkenes, chloroform, etc.; the second category, ketones, alcohols, esters, toluene, xylene, etc.; Category III, petrol, petroleum spirits, turpentine, mineral spirits, etc.
The flash point of the solvent is the lowest temperature at which the flame can ignite when it is on the vapour on the surface of the liquid, and is a possible indication of the occurrence of a fire; it must be fully taken into account when selecting the solvent, and the method of handling it must be clearly stipulated in the technological regulations.
Mature factories should establish a sound local climate records and construction records and case files, including temperature, humidity, the range of changes, etc., the accumulation of basic information to facilitate access to more scientific experimental data, according to the changes in the development of a reasonable solvent use of process protocols.
In short, many defects in the coating film in the coating is caused by improper selection and use of solvents, while the hidden danger of factory fires and neglect of solvents, solvent waste, sediment management, the fundamental reason for the use of solvents used in the nature and use of the solvents do not know very well caused by. Therefore, careful selection of solvents will be the basis for ensuring high quality products and safe production.
