Base materials and weather-resistant color-based materials play a decisive role in the performance of coatings. Facade finishes are affected by ultraviolet rays, sun and rain, and the effect of UV is greatest. It can make the base polymer chemical reaction and deterioration. If the emulsion polymer contains polyethylene, polyacrylate, polymethacrylate, polystyrene, polyvinyl chloride, polyvinyl acetate how to moistureproof a wood bathroom decoration for sale and polybutadiene, etc., subject to ultraviolet radiation, it is easy to break the main chain, Or degradation reaction.

So that the polymer in the base material due to cross-linking or degradation will cause changes in the physical properties of the coating: intermolecular crosslinking will reduce the elongation, and the main chain break will reduce the strength of the coating, and ultimately engineered lumber prices lead to external coating yellowing or powder The Therefore, in the preparation of high-performance exterior paint should pay attention to the choice of base material, select the weather resistance of the emulsion as a base material.

Silicone modified acrylic emulsion and water emulsion polyurethane is the fastest growing, most promising prospects of the coating base varieties. Of course, the weatherability of Composite Decking Furniture Supplier India the emulsion is not only related to the variety, but also with the emulsion emulsion particles size and emulsification system are closely related. The finer the emulsion particles, the more perfect the coating film formed, and the weatherability is also better. In addition, the addition of a certain amount of UV absorber in the emulsion can reduce the damage to the How to Make a Outside Deck coating by ultraviolet rays.
