Products for Tile Adhesive
RDP, HPMC, and HEMC are essential additives in modern tile adhesive formulations, each contributing critically to optimized performance.
Redispersible Polymer Powder (RDP) serves as the key component for enhancing tile adhesive strength and flexibility. It forms a cohesive polymer film that bonds strongly to both tile and substrate, improving resistance to shear stress, dynamic loads, and thermal movement. Additionally, RDP significantly boosts water resistance and long-term durability in tile adhesive systems.
Hydroxypropyl Methylcellulose (HPMC) and Hydroxyethyl Methylcellulose (HEMC) function as vital water-retention and rheology modifiers in tile adhesive. They prevent rapid water loss into absorbent substrates, ensuring adequate cement hydration and proper RDP film formation. These cellulose ethers also deliver excellent workability, extended open time, and enhanced anti-sag performance—essential qualities for large-format tile adhesive applications.
Together, RDP and HPMC/HEMC create a synergistic system that guarantees strong adhesion, reliable application properties, and enduring performance in diverse tile adhesive scenarios.
