What properties of mortar can be improved by redispersible latex powder?

The modification of cement mortar by polymer makes them complement each other, so that polymer modified mortar can be used in many special situations.In addition,

Resin powder. It’s a kind of white powder with good fluidity, which is made of high molecular polymer resin,ultra-fine load anti-consolidation agent and a variety of functional additives.

1.Improve the impact resistance, performance and wear resistance of mortar.

Internal and external wall putty powder, ceramic tile binder, ceramic tile sewing agent, dry powder interface agent, external wall external thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external thermal insulation dry mixed mortar.

At present, redispersible latex powder is widely used in concrete due to its good storage stability, storage period, no deterioration due to freezing or water volatilization, simple packaging, convenient transportation, and can be mixed with cement, gypsum and other raw materials at will.

The redispersible latex powder product is a water-soluble redispersible powder, divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., powder bonded after spray drying It uses polyvinyl alcohol as a protective colloid.
