Key features

Forms a strong and durable film after redispersion. Greatly enhances adhesion to various substrates like concrete, wood, tiles, and other building materials .

The ethylene component provides permanent internal plasticization. This significantly improves the flexibility and deformability of mortars, effectively preventing cracks .

Forms a film with good hydrophobic properties. Provides excellent waterproofing, freeze-thaw stability, and resistance to UV aging and alkalinity .

Dissolves and disperses quickly in water to form a stable emulsion. Improves the rheology, open time, and anti-sagging properties of dry-mix mortars for easier application .

A crucial additive in dry-mix mortars. Enhances compressive strength, abrasion resistance, and cohesiveness. Widely used in tile adhesives, putty, thermal insulation systems, and self-leveling compoun

Product Q&A

Q:What is VAE/RDP used for?

VAE/RDP is a redispersible polymer powder used in dry-mix mortars. It enhances adhesion, flexibility, and durability in tile adhesives, putty, insulation systems, and self-leveling compounds.

Q:What is the recommended dosage?

Dosage depends on application. Tile adhesives typically use 1%-3% of total weight. External insulation systems use 1%-2%. Putty and repair mortars use 0.5%-2%. Testing is recommended.

Q:How does it improve mortar performance?

It increases bonding strength, improves flexibility, enhances water resistance, and reduces cracking risk. It also extends open time and improves workability during application.

Q:Is it suitable for outdoor use?

Yes. It offers good weather resistance, UV stability, and freeze-thaw durability. Suitable for exterior wall systems and outdoor tile installations.

Q:What is the shelf life?

12 months when stored in a cool, dry place. Keep packaging sealed. Avoid moisture, high temperature, and direct sunlight. Opened bags should be used promptly.
