VAE RDP Redispersible Latex Powder Polymer Powders for Wall Putty and Tile Bond

VAE Redispersible Latex Powder Polymer Binder

RDP Product
VAE redispersible latex powder is a free-flowing powder formed by spray drying of VAE emulsion. It is a water-soluble redispersible powder. With polyvinyl alcohol as a protective colloid, it can be easily redispersed in water to form a stable emulsion. Has the original superior performance of VAE emulsion. By adding powder, the performance of mortar with cement or gypsum as the substrate can meet the needs of various constructions and constructions, and it is widely used as a bonding agent for construction materials and adhesives.

When the dry powder mortar added with VAE redispersible powder is stirred with water, the polymer particles disperse on their own and do not stick to the cement. Due to the lubrication effect between the VAE redispersible powder particles, the components of the mortar can flow independently. VAE redispersible latex powder introduces air into the mortar, giving the mortar compressibility, so it can improve the workability of the mortar. When the redispersible emulsion loses moisture, it can form a highly flexible and cohesive polymer film, which can improve the mortar's cohesive ability and cohesion, increase the bending strength, and significantly improve the mortar.

Redispersible latex powder performance
it has outstanding waterproof performance, good bonding strength, increases the elasticity of the mortar and has a longer open time, imparts excellent alkali resistance to the mortar, and improves the adhesion/adhesion, flexural strength, plasticity and resistance of the mortar in addition to abrasion performance and workability, it has stronger flexibility in the flexible anti-cracking mortar.
　　The role of redispersible latex powder:
　　The redispersible latex powder is dispersed to form a film and act as a second adhesive to enhance it;
　　 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 entire mortar system as a reinforcing material, thereby increasing the cohesion of the mortar;
　　the role of redispersible latex powder in wet mortar:
　　Improve construction performance;
　　improve flow performance;
　　increase thixotropy and sag resistance;
　　 improve cohesion;
　　 extend the opening hours;
　　enhance water retention.
　　The effect of redispersible latex powder after curing of mortar:
　　Improve tensile strength;
　　 increase bending strength;
　　 reduce the modulus of elasticity;
　　 improve deformability;
　　 increase material density;
　　increase wear resistance;
　　 improve cohesive strength;
　　 reduce the carbonization depth;
　　 reduce material water absorption;
　　 make the material have excellent water repellency (adding water repellent latex powder)

RDP Usage
Thermal insulation system, ceramic tile adhesive and joint filler, surface repair mortar, surface mortar, self-leveling mortar, repair mortar, polymer waterproof mortar, water-resistant putty, etc.

RDP Storage
VAE redispersible latex powder should be stored in a cool and dry place. The recommended period of use is six months. Please use it as early as possible in summer. If stored in a high temperature and humid place, it will increase the probability of caking. Open the bag After that, please use it as soon as possible, otherwise you need to seal the bag mouth to avoid absorbing moisture from the air.
Due to the thermoplastic nature of the powder, the product height should not exceed one pallet.
