Redispersible Polymer Powder (RDP)
CAS: 24937-78-8
Redispersible Polymer Powder (RDP) is spray dried redispersible emulsion powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity.
Redispersible Polymer Powder RDP improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.
