Analysis of the Performance and Function of VAE Re-dispersible Polymer Powder

VAE Re dispersible Polymer Powder is a water-soluble redispersible powder that is a copolymer of ethylene and vinyl acetate, using polyvinyl alcohol as a protective colloid. Due to their high adhesion and unique properties, such as water resistance, workability, and thermal insulation, VAE Re permeable Polymer Powders have an extremely wide range of applications. Redispersible emulsion powder is mainly used in various dry mixed mortars such as putty powder for internal and external walls, ceramic tile adhesive, ceramic tile pointing agent, dry powder interface agent, external wall thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, etc. Redispersible latex powder is a green, energy-saving, high-quality, multi-purpose powder building material, and an essential functional additive for dry mixed mortar. It can improve the performance and strength of mortar, improve the bonding strength between mortar and various substrates, and improve the flexibility and variability, compressive strength, flexural strength, wear resistance, toughness, adhesion, water retention, and constructability of mortar. In addition, latex powder with hydrophobicity can make mortar have good waterproof performance.

The role of VAE Re persistent Polymer Powder:

1. VAE Re-dispersible Polymer Powder is dispersed to form a film and acts as a second adhesive to strengthen it;

2. The protective colloid is absorbed by the mortar system (it will not be damaged by water after film formation, or "secondary dispersion";

3. The film-forming polymer resin is distributed as a reinforcing material throughout the mortar system, thereby increasing the cohesion of the mortar; Redispersible emulsion powder is a kind of powder adhesive made by special lotion (high polymer) after spray drying. After contacting with water, this powder can be quickly re dispersed to form lotion, and has the same properties as the initial lotion, that is, the water can form a film after evaporation. This film has high flexibility, high weather resistance and high adhesion to various substrates.
