Basic Concept of Redispersible Powder

0 Comment

Basic Concept of Redispersible Powder   The Redispersible Powder is the main additive of dry powder ready-mixed mortar such as cement-based or gypsum-based. The Redispersible Powder is a polymer of vinyl acetate and ethyl ester which is spray-dried and gathered from the original 2μm to form spherical particles of 80-100μm. Since the surface of these.. read more →
