Technical terminology of the flooring industry

1. Tack-free time

For a certain thickness of wet paint film, the time it takes for the surface to change from liquid to solid

2. Working time

The time required from the application of a certain thickness of the liquid paint film to the formation of a solid paint film

3. Transparency

Transparency can indicate whether varnishes and paints contain mechanical impurities and the ability of turbid substances to transmit light

4. Density

Under the specified humidity, the common unit of mass per unit volume of an object is kilogram per cubic meter (kg/m3), gram per cubic centimeter (g/cm3)

5. Viscosity

The internal resistance of a liquid to flow

6. Solid content

The amount of non-volatile matter contained in the coating is generally expressed as a percentage of the mass of the non-volatile matter, and can also be expressed as a volume percentage

7. Storage stability

Under the specified conditions, the degree of resistance of the coating product to changes in performance such as peculiar smell, consistency, crusting, coarsening, sinking, agglomeration, etc. after storage

8. Compatibility

The ability to mix one product with another without causing adverse consequences (such as precipitation, coagulation, thickening, etc.)

9. Grinding fineness

A measure of the degree of dispersion of pigments and extender pigments in paints, that is, under specified conditions, the reading obtained on a standard fineness meter. This reading indicates the depth of a groove on the fineness meter, generally expressed in microns.

10. Hiding power

The ability of the color paint to eliminate the color or color difference on the substrate

11. Recoatability

The difficulty and effect of multi-layer coating of the same paint

12. Paint film thickness

A measure of the thickness of the paint film, generally expressed in microns

13. gloss

An optical property of a surface is expressed by its ability to reflect light

14. Constructability

The difficulty of paint application. Good paint application. Generally, it means that the paint is easy to apply and has good leveling, no sagging, wrinkling, edge shrinkage, bleeding, biting, moderate dryness, easy sanding, and good recoatability. And low requirements for construction environmental conditions

15. Adhesion

The firmness of the bond between the paint film and the coated surface The coated surface can be a bare substrate or a painted substrate

16. Hardness

The ability of the paint film to resist mechanical forces such as collision, depression, scratching, etc.

17.flexibility

The ability of the paint film to deform with its substrate without being damaged

18. Wear resistance

Resistance of paint film to friction

19. yellowing

The tendency of the paint film to turn yellow during the aging process

20. Temperature resistance

The ability of the paint film to maintain its original performance after being subjected to alternating temperature changes with cold and heat

21. Send flowers

Color paints containing a variety of different pigment mixtures segregate or float out during storage or drying, and show uneven color streaks and spots on the surface of the color paint film.

22. floating color

Extreme condition of blooming

23. Bubbles

The air or solvent vapor and other gas or both bubbles formed during the coating process can disappear during the drying process of the paint film, or it can exist permanently

24. Pinhole

A kind of pathological condition in which there are pores in the paint film similar to a needle prick

25. wrinkling

The paint film presents several regular wrinkles in the form of small wave amplitude ripples, which can penetrate part or all of the paint film

26. orange peel

The surface of the paint film has an orange peel-like appearance.

27. whitish

During the drying process of glossy paint, the paint film sometimes appears milky white.

28. Brush marks

After brushing, the phenomenon of ridges left on the dry paint film. This is caused by the paint drying too fast, the viscosity is too large, the paint brush is too rough and the brushing method is improper and the paint film cannot be leveled.

29. Shrinkage

The phenomenon of a number of circular pits of different sizes and different distributions that remain after the paint film is dried

30. Bite the bottom

When the same or different kinds of paint are applied to the dry paint film, the phenomenon of softening and swelling of the dry film underneath or detachment from the substrate during the application or drying of the coating (usual appearance such as wrinkles)
