Redispersible Polymer Powder VAE RDP Powder
September 6th 2024
The redisperside polymer powder is water-soluble redispersible powder, which is divided into ethylene/vinyl acetate copolymer, vinyl acetate/ethylene tert carbonate copolymer, acrylic acid copolymer, etc. The powder adhesive made after spray drying uses polyvinyl alcohol as protective colloid. This kind of powder can be quickly redispersed into lotion after contacting with water. Because redisperside polymer powder has high adhesive ability and unique properties, such as water resistance, workability and heat insulation, their application range is extremely wide.
Function:
The redisperside polymer powder can form a film and serve as the second adhesive to enhance its properties;
Protect the colloid from being absorbed by the mortar system (It will not be damaged by water or “secondary dispersion” after film formation);
The film-forming polymer resin is distributed as a reinforcing material throughout the entire mortar system, thereby increasing the cohesion of the mortar.
In wet mortar
Improve construction performance;
Improve flow performance;
Increase thixotropy and sag resistance;
Improve cohesion;
Extend the opening hours;
Enhance water retention.
After mortar solidification
Improve tensile strength;
Increase bending strength;
Reduce the elastic modulus;
Improve deformability;
Increase material density;
Increase wear resistance strength;
Improve cohesion strength;
Reduce the depth of carbonization;
Reduce the water absorption of materials;
Make the material have excellent water enhancing properties (by adding water enhancing adhesive powder).
