Vinyl acetate ethylene (VAE) copolymer redispersible powder is a polymer powder widely used in the construction industry. It is a free-flowing powder produced by spray drying a mixture of vinyl acetate monomer, ethylene monomer and other additives.
VAE copolymer redispersible powders are commonly used as binders in dry mix formulations such as tile adhesives, self-leveling compounds, exterior insulation systems and cement renders. It improves the mechanical properties and processability of these building materials.
When VAE copolymer redispersible powder is mixed with water, it forms a stable emulsion, making it easy to redisperse and incorporate into formulations. The polymer then acts as a film former, enhancing the final product’s adhesion, flexibility and water resistance.
Some of the advantages of using VAE copolymer redispersible powders in construction applications include:
Improved Adhesion: Polymer powders enhance adhesion between various substrates, promoting better bonding.
Increased Flexibility: It imparts flexibility to dry-blend formulations, reducing the risk of cracking and improving overall durability.
Water Resistance: The redispersible powder forms a water-repellent film that protects the substrate from moisture-related damage.
Enhanced processability: VAE copolymer redispersible powders improve the processability and processability of dry blend formulations, making them easier to apply and spread.
Improved impact resistance: The addition of polymer powders enhances the impact resistance of the final product, making it more resistant to physical stress.
