Shandong Xindadi redispersible polymer powder is a free-flowing organic polymer powder produced by spray-drying a special aqueous emulsion (primarily composed of vinyl acetate-ethylene
copolymer (VAE)). It redisperses in water and, upon evaporation, forms a thin film through the coalescence of individual polymer particles. This film acts as an organic binder,
bonding dissimilar substrates together, strengthening the mortar structure, and providing excellent adhesion at the interface between cement-based and gypsum-based dry-mix mortar
substrates.
