TMPTA Monomer

Due to its excellent recyclability, TMPTA Monomer is a highly sought-after industrial monomer in the chemical industry. Photopolymer and flexographic printing plates and photoresists, as well as acrylic glues, adhesives, and anaerobic sealants, are all examples of products that use it. Polymer-impregnated concrete, wire and cable extrusion, wire and cable impregnated paper, and polymer concrete structural composites are all products made from this material. According to a statement made by the National Cancer Institute, the widespread manufacture and use of trimethylolpropane triacrylate, the dangers of human exposure, and the lack of study into the substance’s long-term toxicity and carcinogenicity are all factors to consider.

There are several uses for this functional monomer because of its high boiling point, high activity level, low volatility, and low viscosity. The functional monomers trimethylopropane triacrylate and trimethylopropane triacrylate are both trimethylopropane triacrylates. This trimethylopropane triacrylate can also be utilized as an active diluent for crosslinking acrylic polymer compositions because of its excellent solubility in acrylic polymer. Aside from that, it is employed in the creation of light ink as well as surface treatment and a range of other processes and applications.

Properties of TMPTA Monomer

Trimethylolpropane triacrylate is characterized by its acrylic or strong odor, as well as by its boiling temperature of more than 200° C at 1 mm Hg, which is higher than the boiling point of water. The specific gravity of water is 1.1084 at 25°C, the vapour pressure is less than one millimetre Hg, and the refractive index of water is 1.4736 at 20°C, all within the same temperature range. It should not be used in conjunction with strong oxidizing agents, acids, or bases, and it should not be used in water in. When exposed to direct sunshine and heat, trimethylolpropane triacrylate can spontaneously polymerize; however, the monoethyl ester of hydroquinone can assist prevent this from occurring. The flash point of trimethylolpropane triacrylate is more than 110 degrees Celsius. Carbon monoxide and carbon dioxide are released into the environment as a result of the breakdown process. In order to mitigate its reactivity, the chemical is only available on the market in technical grade form.

When it comes to industrial applications, technical grade chemicals are permissible unless a higher purity grade is needed. Although technical grade chemicals are routinely used in big commercial production, they are not suited for applications that need impurity levels that are far lower than those utilized in commercial manufacture.

TMPTA of technical grade is made by esterifying trimethylolpropane, with acrylic acid present as a known contaminant throughout the process of esterification. TMPTA was expected to be produced in quantities ranging between 10 and 50 million pounds according to the United States in 2019 Inventory Update Reporting.

Due to the low volatility of TMPTA, its resistance to weather, chemicals, water, and abrasion, and its ability to cure quickly when heated are all benefits of the compound. For the reasons stated above, it is used in the production of adhesives, plastics, sealant chemicals (including paint additives), photosensitive chemicals (including ink and toner), and other goods, among other things. TMPTA is used in a range of products, such as alkyd coatings and dental polymers. It is also found in hardwood flooring and concrete polymers, screen printing and elastomers, automotive lights and acrylics, among other things.

TMPTA Monomer Uses

The chemical compound trimethylol propane triacrylate is a type of triacrylate that is commonly used in the electronics industry to create UV-curable lithographic inks, varnishes, artificial nails, wood finish solder, and etch resists, among other things. It is derived from propane trimethylol triacrylate as stated earlier.

Trimethylolpropane triacrylate (TMPT) is a versatile methylolpropane monomer with several industrial uses, including cross-linking agent, reactive diluent, and chemical intermediate. These include thermal paper, plastic hardener, optical fibers, UV-cured acrylate varnishes used in the furniture sector as well as polymers and resins. Photopolymer plates and flexographic print resists, as well as anaerobic sealants and acrylic glue and adhesives, are all examples of further uses for this material. Colloidal dispersions for industrial baked coatings, waterborne and solvent-based alkyds, and vinyl/acrylic nonwoven binders are just a few examples of the many uses of this technology. Polymer concrete impregnated concrete, wire and cable extrusion, and superabsorbent polymers for newborn diapers are just a few examples of the wide range of items that may be manufactured with this technique. Following industrial applications that are most common:

  • Adhesives and sealant chemicals
  • Glass reinforced resin
  • Intermediates
  • Paints additives and coating additives
  • Photosensitive chemicals
  • Processing aids

TMPTA is a triacrylate that is also used in a range of electronic goods, including UV-curable lithographic inks and varnishes, artificial nails, and wood finish solder.

As coatings

It is a reactive diluent that is present in ultraviolet and electron-beam cured coatings and inks, as well as a variety of other curable substances. The hardness and chemical resistance of the polymer are increased by crosslinking it with trimethylopropane triacrylate after it has been cured. Furthermore, TMPTA is a low-cost radiation curing diluent that may be used in conjunction with a wide range of acrylated resins to cure them.

As manufacturer

Three-functional monomer TMPTA, which is used to make plastics, adhesives, acrylic glue, anaerobic sealants, and ink, is used in the production of these products.

As a Solvent

Because of its low volatility and quick cure reaction, trimethylopropane triacrylate is a preferred solvent. TMPTA is a solvent that is widely used. Trimethylopropane triacrylate is resistant to a variety of environmental conditions, including weathering, chemical water, and abrasion. Specifically, TMPTA is a dry process solvent that is used in the production of coatings and inks, as well as in the polymerization process in the industry.

For indoor printing

Dry indoor printing with ink cartridges, which is done by professionals, makes use of a different kind of trimethylopropane triacrylate. The aliphatic trifunctional acrylate TMPTA has a low viscosity and a high cross-linking activity, and it is used in the production of plastics. Use of TMPTA reactive diluent is beneficial for polyurethanes, polyesters, epoxy resins, and polyurethane-based compositions, among other things.

Genotoxicity tests

TMP Triacrylate has been subjected to an extensive number of genetic testing procedures, both in vitro and in vivo, during the course of its development. TMPTA has not been proven to cause gene mutations in bacteria or mammalian cells in vitro, but clastogenicity has been established by the development of small colony to mutants in a mouse lymphoma experiment, as well the induction of micronuclei and chromosomal abnormalities in human cells.

Bone marrow or blood micronucleus tests following repeated oral or topical application of TMP Triacrylate were shown to be non-toxic despite the drug’s plasma (and consequently tissue) concentrations estimated to be larger than those necessary to elicit clastogenic effects in vitro. Following intravenous injection, it had no clastogenic effects in mice’s bone marrow or liver. TMPTA does not appear to be a genotoxic agent when evaluated in a laboratory, according to the evidence shown thus far.

Reaction with propyleneimineto from polyfunctional aziridine

In the presence of polyfunctional aziridine, trimethylopropane triacrylate reacts with propyleneimineto, resulting in the formation of trimethylopropane triacrylate. It was discovered that textile fabric printers were sensitive to light. Patch experiments using aziridine hardener produced positive results; patch tests with trimethylopropane triacrylate, on the other hand, produced poor results. When a worker in the optical fiber manufacturing business was exposed to trimethylopropane triacrylate, a sensitizer often used in floor top coatings and photopolymerizable inks, he acquired contact dermatitis.

As a chain extender

Trimethylopropane triacrylate is a chain extender that can be utilized in a number of applications. This material has a low melting point. It is flammable. As a result of being exposed to the outdoors, it has an exceptional ability to absorb moisture. It may be dissolved in a variety of solvents, including water, acetone, carbon tetrachloride, chloroform, and ether, among others. It is insoluble in fatty and aromatic hydrocarbons and has a good compatibility with alkyl resins, saturated polyesters, and polyurethanes, among other things.

Exposure

It is possible that those who deal with TMPTA during its manufacturing, processing, handling, and application will be exposed to the dangers of the chemical. According to the National Institute for Occupational Safety and Health, between 1981 and 1983, 4,180 employees were exposed to trimethylolpropane triacrylate. Trimethylolpropane triacrylate, which may be found in latex paints, furniture, and floor polishes, may expose consumers to excessive quantities of methylolpropane triacrylate.
