Redispersible Polymer Powder

详情

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)
