Color appearance: color appearance is the color and appearance of the paint when the can is opened in a homogeneous state.

Fineness: Fineness is the size of the color and filler in the paint, generally expressed in microns.
Viscosity: Viscosity is a measure of the internal resistance to flow that a fluid has. It is generally expressed in centipoise, seconds, and Krebs units.
Density: Density, also known as specific gravity, is the mass of a unit volume of paint at a specified temperature, expressed in g/ml.
Solid content: Solid content, also known as non-volatile content, is the total amount of non-volatiles contained in the paint component, generally expressed as the mass percentage or volume percentage of non-volatiles.
Finger pressure dry: Finger pressure dry, also called hard dry, is when the paint film is pressed with the thumb instead of twisting it, the film has no indentation. It is expressed by the time it takes for the paint film to reach this level.
Sandable time: sandable time is when the paint film is sanded with sandpaper without sticking to the sandpaper. It is expressed as the time needed for the paint film to reach this degree.

Activation period: Activation period is the time interval from the time the paint is deployed to the construction viscosity to the time when construction cannot be carried out.
Gloss: Gloss is the ability of the surface of the paint film to reflect the light shining on it in a certain direction, also called mirror gloss. For different gloss, you can choose 20 degree, 60 degree, 85 degree gloss meter for measurement respectively.
Transparency: (The most important concern for varnish) Transparency is the degree of clarity of the wood grain and substrate color after the paint film dries.
Repaintability: Repaintability is the degree of difficulty and effect of multi-layer coating by the same paint.
Covering power: Covering power is the ability of the color paint to eliminate the color or color difference on the substrate.
Contrast ratio: Contrast ratio is the ratio of reflectance of the coating film on a specified black and white substrate, expressed as a decimal or percentage.
Hardness: Hardness is the ability of a paint film to resist mechanical forces such as collisions, indentations, and scratches. It can be expressed by pencil hardness.

Adhesion: Adhesion is the firmness of the bond between the paint film and the painted surface. The painted surface can be a bare substrate or a painted substrate.

Flexibility: Flexibility is the ability of the paint film to deform along with the substrate without damage.
Impact resistance: Impact resistance is the ability of the paint film to deform rapidly under heavy hammer impact without cracking or falling off from the substrate.
Feel: Feel is the degree of smoothness and delicacy of the paint film.
Fullness: Fullness is the extent to which the surface of the paint film is flat and plump.
Leveling: Leveling is the degree to which the coating film can flow and eliminate the coating marks after construction, and the degree to which uniform and flat coating film can be obtained after drying.
Fillability: Fillability is the extent to which the dry film of paint can fill the wood eye.

Polishability: Polishability is the degree of difficulty to produce a flat and light-free surface after the paint film or putty layer is polished with sandpaper and other materials.

Scratch resistance: scratch resistance is the ability of the dried paint film to resist scratching by objects such as paper and chicken feather duster.
Yellowing resistance (white paint is the most important concern): Yellowing resistance is the ability of the paint film to resist yellowing caused by ultraviolet light and other damage.
Solvent resistance: The ability of the paint film to resist erosion by organic solvents.
Water resistance: Water resistance is the ability of the paint film to resist the action of water. That is, under the specified conditions, the film test plate will be immersed in water, observe whether there is whitening, loss of light, blistering, peeling and other phenomena, as well as the degree of difficulty in restoring the original state.
Scrub resistance: Scrub resistance is the ability of the paint film to be repeatedly scrubbed with washing medium under the specified conditions without damage.
Stain resistance: It is the ability of the paint film to resist staining by dust, handwriting and other pollutants without discoloration and dirt being removed to eliminate its effect on the coating film.

Weather resistance: is the ability of the paint film to resist the damaging effects of sunlight, rain, dew, wind, frost and other climatic conditions (loss of light, discoloration, chalking, cracking, mold, peeling, etc.) and maintain the original performance.
Abrasion resistance: It is the ability of the paint film to resist the action of friction. The common method is to measure the weight loss of the paint film under a certain load, after a specified number of grinding revolutions, expressed in grams.
Anti-powdering: Anti-powdering is the ability of paint film to resist powdering caused by ultraviolet light, water vapor, oxygen, etc.
Anti-layering: Anti-layering is the ability of the paint to resist sinking of the powder in the paint in the process of use.
Anti-sagging: Anti-sagging is the ability of paint film to resist sagging after drying.

Constructability: Constructability is the degree of difficulty of paint construction.
Paintability: Paintability is the ease of paint application.

Antifoaming: Antifoaming is the ability of the coating to eliminate the foam generated during the production and painting process.

Compatibility: Compatibility, also known as miscibility, is the ability of a product to mix with another product without producing undesirable consequences (such as precipitation, coalescence, thickening, etc.).
Anti-whitening property: Anti-whitening property is the ability to prevent the paint film from losing its gloss and surface whitening during the drying process after construction.
Anti-greening: Anti-greening is the ability of PE paint to resist greening due to chemical reaction.

Thixotropy: Thixotropy is the ability of the paint to temporarily drop in viscosity and become liquid flow when it receives shear force; when it is not subject to shear force, it returns to the original viscosity.
