Applications of acrylic defoamer

Acrylic antifoam agent is developed according to the production process of textile slurry, printing and dyeing pigment, waterproof coating color paste, and has polymer characteristics of agricultural production system silicon foam antifoam agent. Good compatibility with textile acrylic slurry; outstanding defoaming effect in textile acrylic slurry. With a small amount, easy to disperse in water, does not float, good foam inhibition, acid and alkali resistance, applicable to high and medium temperatures and other properties.

The surface of the building is painted, and a thin film is formed by the volatilization of solvent or water or by the chemical reaction of two components, so that the surface of the building is isolated from water, thus playing the role of waterproofing and sealing, these painted viscous liquid is called waterproof coating. Waterproof coating after curing the formation of waterproof film with a certain degree of extensibility, elasticity, crack resistance, impermeability and weather resistance, can play a waterproof, impermeable and protective role. Waterproof coating has good temperature adaptability, easy to operate, easy to repair and maintenance.
