RDP＆VAE
(Redispersible polymer powder)
This is a white, free-flowing powder produced via the spray-drying of a polymer emulsion; it serves as a crucial functional additive for dry-mix mortars. Even at low dosage levels (typically just 1.0%–5.0%), it significantly optimizes the mechanical properties and durability of the mortar.
Four core functions:
1.Increases bond strength
2.Enhances flexibility and impact resistance
3.Improves mortar cohesion and abrasion resistance
4.Boosts water and weather resistance
Key application areas:
Interior and exterior wall putties
External thermal insulation bonding mortars and crack-resistant rendering mortars
Tile adhesives and tile grouts
Gypsum-based plasters and leveling compounds
Repair mortars, self-leveling compounds, and flooring mortars
