Redispersible Polymer Powder ZONEHIBTM RDP belongs to the emulsion powder of ethylene-vinyl acetate copolymer which can be dispersed in water, it has an excellent flexibility, strong plasticity and abrasion resistance properties and strong transformation ability so as to increase the adhesive strength between mortar and common support and improve the mortarâ??s mechanical performance. In the polymer cement mortar, it can increase the materials anti-bending and anti-tension properties. Therefore, it has excellent anti-crack performance, which can prevent the materials from cracking effectively.
