redispersible polymer powder
The 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:
n redispersible emulsion 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)
