Redispersible Polymer Powder product is white or off white flowable powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid.
Purpose:
◇ ceramic tile adhesive
◇ bonding mortar of external wall external insulation system
◇ external wall external insulation system plastering mortar
◇ tile jointing agent
◇ self flowing cement mortar
◇ flexible putty for inner and outer walls
◇ flexible crack resistant mortar
◇ rubber powder polystyrene particle thermal insulation mortar
◇ dry powder coating
◇ polymer mortar products with high requirements for flexibility
effect:
It has outstanding waterproof performance, good bonding strength, increases the elasticity of the mortar and has a long opening time, endows the mortar with excellent alkali resistance, improves the adhesion / adhesion, flexural strength, plasticity, wear resistance and workability of the mortar, and has stronger flexibility in the flexible crack resistant mortar.
Role of redispersible emulsion powder:
Redispersible Polymer Powder forms a film after dispersion and plays a reinforcing role as the second adhesive;
• the protective colloid is absorbed by the mortar system (it will not be damaged by water after film formation, or "secondary dispersion");
• the film-forming polymer resin is distributed in the whole mortar system as a reinforcing material, thereby increasing the cohesion of the mortar;
Role of redispersible emulsion powder in wet mortar:
• improve construction performance;
• improve liquidity;
• increase thixotropy and sag resistance;
• improve cohesion;
• extend the opening hours;
• enhance water retention.
• role of redispersible emulsion powder after mortar curing:
• improve tensile strength;
• increase bending strength;
• reduce the elastic modulus;
• improve deformability;
• increase the density of materials;
• increase wear resistance;
• improve cohesion strength;
• reduce the carbonation depth;
• reduce the water absorption of materials;
• make the material have excellent water increasing property (add water increasing rubber powder)
