China Vae Chemical Redispersible Polymer Powder Rdp Powder, Find details about China Water Holding, Surface Modification from Vae Chemical Redispersible Polymer Powder Rdp Powder
Re-dispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-based ethylene(VAE), then obtained a free flowing organic polymer powder. It can re-disperse in water and form a film after water evaporation by coalescence of individual polymer particles. The film acts as an organic binder, to glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry-mixed mortar substrate interface.
application
1. Dry powder putty: improve the bonding strength, adhesion to the base layer, continuous film formation, dry powder putty is not affected by weather and humidity, making the product more stable, strong alkali resistance, and excellent waterproof performance.
2. Tile adhesive: It has extremely strong adhesion to the wall and bonding strength, which is necessary for high-grade tiles.
3. Tile refurbishment interface agent: good bonding strength, strong adhesion to the base surface of tiles and other surfaces that are smooth and non-absorbent.
4. External wall insulation: bonding mortar, plastering mortar and other construction mortars, especially suitable for flexible construction mortars.
