Redispersible Powder performance

Lat's see JINJI® Re-Dispersible Polymer Powder performance with good flexibility andperfect waterproof.

The JINJI® Redispersible polymer powder product is white powder, which is a copolymer of ethylene and vinyl acetate, and uses polyvinyl alcohol as a protective colloid. It also nemed RDP, VAE and EVA.


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 polymer powder

RDP 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 RDP after mortar curing: improve tensile strength, increase bonding 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.
