Redispersible polymer powder in construction
Redispersible polymer powder (RDP) is a water-soluble redispersible powder, this powder can be quickly dispersed into emulsion after contact with water, it is ethylene vinyl acetate copolymer (EVA) powder with a special polyethylenol as the protective colloid. It is a powder binder made of dispersible colloid as polyethylene glycol tree finger, additives (inside and outside) to protect the colloid, anti-caking agent and other raw materials, and then made by spray drying.Its main application in construction, with outstanding bond strength, improve the flexibility of mortar and have a long open time, give mortar excellent resistance to breakage, improve the adhesion of mortar, flexural strength, water resistance, plasticity, wear resistance and construction, more flexible in the flexible mortar.
RDP Application areas
Brick binder, joint filler, exterior wall insulation, putty, gypsum mortar, self-leveling, etc.
