Middle layer lacquer

The middle layer is made of lacquer aggregate, binder (base), various additives and solvent composition.

(1) aggregate
Including color aggregate and general aggregate aggregate aggregate of two.
Color is a natural stone aggregate after crushing, washing, screening and other procedures processing, has good weather resistance, acid and non-fading, non-artificial sintered sand. General aggregate chosen white, with quartz sand with high silicon content, due to relatively dim natural powder colors, use color in a single rigid, with a certain amount of white quartz sand used in conjunction with the natural color powder, adjust color depth, so that the coating color rich layering, can achieve a similar texture of natural stone, but also reduce production costs. gradation of aggregate particles of lacquer and coating the construction of the performance of the state is very large, if the aggregate particles are too thick, easy to precipitate in the paint, coating sand when the floor will increase the amount of paint will be large, and decreased opacity coating, coating the appearance of rough, easy to be gathering dust pollution; such aggregate particles are too small, the decorative effect of the poor. Therefore, using weight particles with the use of both the decorative effect difficult to affect the coating, the coating can be dense.
(2), binder (base)
The performance of lacquer binder is a key factor in its direct impact on the real stone paint film hardness, bonding strength, water, weather and other aspects of performance. For the true stone of the emulsion should meet the following three requirements:
A, emulsion stability, the film formed colorless, transparent, easy to ultraviolet irradiation of yellow and pink;
B, higher hardness of the coating to improve coating stain resistant;
C, film of the water expansion ratio is smaller, the formation of water-resistant to bleaching of the film, that is, the ability to resist water whitening.
(3), the finish
Overlay material is mainly used to enhance the lacquer coating is waterproof and stain resistance, resistance to ultraviolet radiation and other properties, but also facilitate future cleaning. Steel finishes, including oil-based two-component polyurethane topcoat transparent cover, oil dual transparent cover sub-fluorocarbon finish, water-based paint and other single-component acrylic cover.
The middle layer lacquer coating formula:
Acrylic emulsion (bond strong, MFT higher emulsion) 30%
60% of natural colored sand stones
10% of additives
