CheV^TM Redispersible Emulsion Powder

CheV Redispersible emulsion powder(abbr.CheV RDP) is an organic polymer powder made by spray-drying aqueous emulsions,which includes ethylene,vinyl acetate,vinyl versatate,acrylic acid etc..

CheV RDP is always combined with cellulose ethers and other additives to improve the properties and performance for the cement based or gypsum based mortar,such as better water-retention,open time,better work-ability, increasing adhesion to a variety of substrate and higher flexural strength and flexibility etc..
