Product Overview

Rigid Redispersible Polymer Powder (RDP)

Rigid Redispersible Polymer Powder (RDP) is a high-performance polymer additive developed to deliver exceptional adhesion, superior hardness, and outstanding durability in cementitious materials. Once blended with water, it disperses uniformly, forming a dense, rigid polymer film that significantly boosts the mechanical strength, cohesion, and overall integrity of mortars and adhesives.

Designed for construction applications that demand a firm, non-flexible bond, Rigid RDP offers enhanced abrasion and water resistance, providing lasting protection even under challenging conditions. It also helps reduce shrinkage and surface cracking, ensuring a stable and durable finish throughout the material's service life.
