Redispersible Latex Powder

RDP Dispersible emulsion powder is a powder binder made by spray drying of a special emulsion (high molecular polymer). The powder can be quickly dispersed into an emulsion after contact with water, and has the same properties as the initial emulsion, that is, a film can be formed after the evaporation of water, which has high flexibility, high weather resistance and high adhesion to various substrates. Redispersible emulsion powder product performance 1. Redispersible latex powder is a very commonly used insulation additive in building materials. The main properties of redispersible latex powder are: It has waterproof performance, good bond strength, increases the elasticity of mortar and has a long opening time, gives mortar excellent alkali resistance, improves mortar adhesion/adhesion, bending strength, plasticity, wear resistance and constructability, and has stronger flexibility in flexible crack mortar. 2, the main fuctions of dispersible emulsion powder are: film formation after dispersion and play an enhanced role as a second adhesive; The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or "secondary dispersion"; The film-forming polymer resin is distributed in the whole mortar system as a reinforcing material, thus increasing the cohesiveness of the mortar. 3, the role of dispersed emulsion powder in wet mortar: improve construction performance; Improve flow performance; Increase thixotropy and sag resistance; Improving cohesion; Extended opening hours; Enhanced water retention; 4, its role after curing mortar: improve tensile strength; Increase bending strength; Reduce the elastic modulus; Improve deformability; Increase the density of the material; Increase wear resistance; Improve cohesion strength; Reduce the carbonization depth; Reduce material water absorption; Make the material water-enhancing (add water-enhancing rubber powder) Third, redispersible emulsion powder recommended use * Dry powder putty * tile binder * Caulking cement * Surface finishing cement * Insulation mortar * tile reconditioning interface agent * Thermal insulation material * Powder type latex paint The VAE dispersible emulsion powder has high bonding ability and unique properties, such as water resistance, constructability and heat insulation. Therefore, their application range is wide. 4. Redispersible latex powder grade packaging 25 kg/bag stored in a cool and dry place, recommended use period of 12 months
