Products for Waterproof
RDP, HPMC, and HEMC are key additives in polymer-modified waterproofing mortars and coatings, transforming rigid cementitious mixes into flexible, durable membranes.
Redispersible Polymer Powder (RDP) is the core component for creating a flexible, crack-bridging polymer film. It significantly enhances adhesion to various substrates, provides elasticity to accommodate structural movement, and drastically reduces water permeability by blocking capillary pores. This results in excellent long-term waterproofing performance.
Hydroxypropyl Methylcellulose (HPMC) and Hydroxyethyl Methylcellulose (HEMC) are essential for the fresh mortar properties. They provide crucial water retention, preventing rapid water loss to absorbent substrates, which ensures complete hydration and proper RDP film formation. They also improve workability, sag resistance, and homogeneity of the mix, ensuring uniform application and consistent film thickness.
Together, this combination ensures the creation of a seamless, adhesive, and highly water-resistant barrier.
