We offer three main types of RDP chemical products. Each type serves different construction applications. Our technical team is always ready to help you choose the right option.
Best for: Applications needing structural stability
Our rigid RDP powder (like Accurate 5011N) works great in tile adhesives for stable surfaces and self-leveling compounds. Even small amounts provide excellent:
Glass Transition Temperature: 15°C
Best for: Projects needing movement tolerance
Our flexible RDP chemical (like Accurate 4025N) is perfect for exterior mortars and flexible tile adhesives. It offers:
Glass Transition Temperature: 0°C
Best for: Self-leveling mortar applications
LANDU ACCURATE Leveling RDP powder maintains mortar flowability while improving:
This product is essential in cement- and gypsum-based self-leveling mortars.
Best for: Moisture-exposed projects
Our hydrophobic Redispersible Polymer Powder resists:
It matches or exceeds the performance of Vinnapas 8034H RDP.
With three factories and an advanced R&D center, we guarantee consistent quality for large orders. We have distributors in many countries including Albania, Poland, Greece, and Switzerland.

Applications
Our RDP powder ensures smooth, even spreading while preventing segregation or bleeding. It adds elasticity to handle substrate movements and improves durability against foot traffic and impacts.
Redispersible Polymer Powder enhances bonding between adhesive, insulation boards, and substrates. After curing, the polymer film adds flexibility to the mortar, which reduces cracking from thermal changes, structural shifts, or wind loads.
In cementitious thin-set mortars, our RDP chemical improves adhesion between challenging surfaces and tiles. It also extends open time for adjusting tiles while maintaining strong grip.
Redispersible Polymer Powder creates better bonds between putty, walls, and decorative materials like paint. It helps create level surfaces while filling minor cracks and resisting common problems like chipping, peeling, and fading.
Our hydrophobic RDP powder is specially designed for waterproofing. The polymer film fills micro-pores and capillaries, reducing water absorption. It also improves abrasion resistance and mechanical strength - essential for exterior wall applications.
