The polymer film formed by Redispersible polymer powder has good flexibility. A film is formed in the gaps and surfaces of the cement mortar particles to form a flexible connection. So that the brittle and hard cement mortar becomes elastic. The mortar added with Redispersible polymer powder is several times higher in tensile and flexural resistance than ordinary mortar.

Redispersible Polymer Powder/Vae for Wall Putty Mortar VAE RDP is a polymer powder with multipurpose, widely used in joint filler mortar , wall putty/wall skim coat and binder as a film forming agent, which is designed to improve the workability, adhesion, flexibility, anti-permeability of construction dry mixed mortar.

The Redispersible Polymer Powder RDP is a special polymer powder made after spray drying.

Dry mortar generally uses Portland cement as the cementing material, and the amount of cementing material generally accounts for 20% to 40% of the dry powder mortar; most of the fine aggregate is quartz sand, and the amount is large, and it generally needs to be dried and screened.

Redispersible Polymer powder is mainly used in all kinds of dry-mix mortar, such as wall putty powder, ceramic tile adhesive, ceramic tile jointing agent, dry powder interface agent, exterior insulation mortar, self-leveling mortar, mending mortar, decorative mortar, waterproof mortar, etc..

Redispersible Polymer Powder’s Functions:
Increase mortar’s impact resistance, durability, and abrasion resistance:

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.
