Silicone elastomers decorative coatings
Flexible silicone latex decorative coatings is to introduce a silicone bond in the acrylic resin polymerized into the new film material. Add silicone improved weathering resistance and durability of an acrylic resin, coating an elongation of 700% to 300%, fine cracks mask wall, the coating layers to improve the decorative features. General multi-step emulsion polymerization into a composite polymer latex, the center of a hard resin. Compared with ordinary glue residue, coating flexibility and better water resistance, higher gloss and hardness, stain resistance is quite high, it is a promising functional coatings. Reactive silicone raw rubber latex solution therefrom, the crosslinking agent and catalyst under certain polymerization conditions, the solution after dehydration crosslinking reaction can be performed at room temperature, to form a silicon emulsion film having a network structure as a whole.
