Frequently Asked Questions
RDP acts as a redispersible polymer that improves the adhesive strength, flexibility, and mechanical properties of cementitious mortars, preventing cracks and increasing durability.
RDP enhances the rheology and water retention of the mixture, making the mortar smoother to apply and extending the open time for installers.
Yes, RDP is frequently used alongside HPMC (Hydroxypropyl Methylcellulose) to create a synergistic effect that maximizes both water retention and adhesive strength.
Due to its ethylene-vinyl acetate copolymer structure, it creates a denser matrix upon curing, which significantly reduces water uptake and permeability.
The specialized chemical manufacturing industry, specifically those producing tile adhesives, wall putties, self-leveling compounds, and external thermal insulation systems (ETICS).
RDP should be stored in a cool, dry, and well-ventilated warehouse, kept away from moisture and heat to prevent premature clumping or degradation.
