Redispersible Polymer Powder(RDP)

CAS: 24937-78-8

Redispersible Polymer Powder (RDP) is spray dried redispersible emulsion latex 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.

It 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.

After spray drying, VAE emulsion is turned into a white powder which is a copolymer of ethyl and vinyl acetate. It is free-flowing and is easy to emulsify. When dispersed in water, it forms a stable emulsion. Possessing the typical characteristics of VAE emulsion, this free-flowing powder offers greater convenience in handling and storage. It can be used by mixing with other powder-like materials, such as cement, sand and other lightweight aggregate, and it can also be used as a binder in building materials and adhesives.
Redispersible Polymer Powder (RDP) dissolves in water easily and quickly forms emulsion.It improves the important application properties of dry mortars, longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.
Protective colloid :P olyvinyl alcohol
Additives : Mineral anti-block agents

Key Properties:

Redispersible Polymer Powder RDP can improve adhesion, flexural strength in bending, abrasion resistance, deformability. It has good rheology and water retention, and can increase the sag resistance of tile adhesives, it can made up to tile adhesives with excellent non-slump properties and putty with good properties.

Special features:

Redispersible Polymer Powder RDP has no effect on rheological preperties and is a low-emissions,

General – purpose powder in the medium Tg range. It is eminently suitable for

formulating compounds of high ultimate strength.
