Construction
RDP
FEATURES
General Properties: Vinyl acetate-ethylene (VAE) or acrylic copolymer powders; free-flowing white powders.
Synergistic Role: As RDP particles disperse in water and form films, they stabilize foam. Powdered defoamers (often blended directly into the dry mix) must instantly break this foam upon water addition to prevent air entrapment in the hardened mortar.
Performance Benefits:
Maximizes Mortar Density: Eliminates entrapped air, ensuring optimal compressive and flexural strength.
Prevents Surface Pinholes: Stops foam from migrating to the surface, ensuring a smooth, defect-free finish.
Enhances Adhesion: A denser, air-free mortar matrix provides better bonding to substrates.
