High Grade Redispersible Polyvinyl Acetate Ethylene Copolymer Powder - 12% Purity, White Color, Excellent Alkali Resistance, Superior Adhesion And Flexibility

Re-dispersible polymer powder(VAE)- - - is a free-flowing ethylene-vinyl acetate copolymer white powder formed by spray-drying EVA emulsion, easily re-emulsified and dispersed in water to form a stable emulsion.In addition to the original superior performance of EVA porous liquid, and because it is a free-flowing powder, it has excellent convenience and reliability in handling and storage.

Composition:
1.Polymer resin: located in the core part of the powder particles, is also the main component of the role of re-dispersible polymer powder, for example, polyvinyl acetate/ethylene resin.
2.Additives: together with the resin to play the role of the modified resin, such as reducing the temperature of the resin film forming plasticizer(usually vinyl acetate/ethylene copolymer resin does not need to add a plasticizer).Not every powder has an additive component.
3.Protective colloid: a layer of hydrophilic material in the surface of the redispersible polymer powder particles wrapped Lee, the vast majority of redispersible polymer powder protective colloid is polyvinyl alcohol.
4.For additives (outside): for further expansion of the performance of the dispersible polymer powder and another added material.Such as adding superplasticizer in some of the Fluidic powder.As with additives, not every dispersible polymer powder contains such additives.
5.Anti-caking agent: fine mineral fillers, mainly used to prevent caking powder in the storage and transportation process and to facilitate the flow of powder(from a paper bag or tank dump out).

Redispersible milk powder has a high adhesion and unique properties, excellent mortar alkali resistance, thereby improving mortar adhesion, flexural strength, water resistance, plasticity, wear resistance and construction, the flexible crack mortar has more flexibility.
