Redispersible rubber powder is an essential and important functional additive for dry mixed mortar, a powder building material of “green environmental protection, building energy conservation and advanced multi-purpose”. It can improve the performance of mortar, improve the strength of mortar, improve the bonding strength between mortar and various substrates, and improve the flexibility and deformability, compressive strength, flexural strength, wear resistance, toughness, adhesive force, water holding capacity and constructability of mortar. In addition, the hydrophobic rubber powder can make the mortar have good water resistance.
Redispersible rubber powder is mainly used in various dry mixed mortars such as internal and external wall putty powder, ceramic tile binder, ceramic tile pointing agent, dry powder interface agent, external wall external insulation mortar, self leveling mortar, repair mortar, decoration mortar, waterproof mortar and so on.
