VAE/RDP Powder

Redispersible polymer powder, also known as VAE Chemical or RDP Chemical, is a powder binder made from a special emulsion (high molecular polymer) spray-dried. The VAE/RDP powder can be quickly dispersed to form an emulsion after solving into water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and good adhesion to various material, is an essential functional additive for dry-mix mortar.

Features of Redispersible Emulsion powder:

• High adhesion and bonding strength

• Water resistance

• Good workability and rheology

• Improved flexibility and durability

• Increased impact and abrasion resistance

• Good freeze-thaw stability

Application areas of VAE Chemical:

Redispersible Emulsion powder is mainly used in interior and exterior wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, interior and exterior wall insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc.

• Mortar and grout: RDP powder is used in cement-based mortars and grouts to improve their adhesion, workability, and durability.

• Tile adhesives: VAE powder is added to tile adhesives to increase their bonding strength, water resistance, and flexibility.

• Exterior insulation and finishing systems (EIFS): RDP powder is used in EIFS to improve the system’s flexibility, adhesion, and resistance to cracking.

• Self-leveling compounds: VAE powder is added to self-leveling compounds to enhance their workability and durability.

• Gypsum-based products: RDP powder is used in gypsum-based products to improve their water resistance, adhesion, and strength.
