redispersible polymer powder products are water-soluble re-dispersible powder, divided into ethylene/vinyl acetate copolymer, ethylene acetate/tertiary carbonate copolymer, acrylic acid copolymer, etc., the powder adhesive made after spray drying, with polyvinyl alcohol as the protective colloid.

The most valuable method to test the quality of RDP is to add it in dry mixed mortar, to see the behavior of dry mixed mortar in 28 days and years. But there is quick method to feel the quality of RDP.

Redispersible polymer powder is produced by high temperature and high pressure, spray drying, and with a variety of activities to enhance powder homopolymerization. It can make mortar obviously increase the bonding ability and its tensile strength, resistance to drop, water thickening and construction performance is good. Water resistant, freeze-thaw resistance, heat-resistant ageing performance is outstanding. Ingredients are simple and easy to use.

Redispersible polymer powder is water-soluble redispersible powders. It is divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., and is powder bonded after spray drying.

Redispersible polymer powder is a water-soluble redispersible powder, the most common is ethylene-vinyl acetate copolymer, and uses polyvinyl alcohol as a protective colloid. Therefore, redispersible polymer powder is very popular in the construction industry market.

Redispersible polymer powder features and applications in dry mix mortar

Redispersible polymer powder can improve the bending strength and adhesion strength of the mortar because it can form a polymer film on the surface of the mortar particles, and there are pores on part of the surface of the film, and the pore surface is filled with the mortar,

Redispersible polymer powder(RDP) and other inorganic adhesives (such as cement, slaked lime, gypsum, clay, etc.) and various aggregates, fillers and other additives (such as hydroxypropyl methyl cellulose, starch ether, cellulose fiber, etc.) After physical mixing, dry-mix mortar is made.

RDP has extremely outstanding bonding strength, improve the flexibility of mortar and have a long opening time, give the mortar excellent alkaline resistance, improve the mortar adhesion, flexural strength, water resistance, plasticity, wear resistance and construction, in the flexible anti-crack mortar more has a strong flexibility.
