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.

Our dedicated R&D Center ensures quality through thorough testing of raw materials and finished products. We continuously innovate in RDP chemical production to set new industry standards.
LANDU holds ISO 9001 and EU REACH certification. Our products are exported to over 60 countries with extensive experience working with multinational corporations.
With three major factories and 75,000 tons of annual production capacity, we can quickly deliver large orders of Redispersible Polymer Powder.
Everything you need to know about LANDU's RDP production and quality control
Plenty of stock, fast delivery, huge capacity: We have 7 storage tanks, each holding 100 tons, for a total of 700 tons of raw material reserves.
This substantial inventory means that even with sudden demands or supply chain challenges like during the pandemic, we can still guarantee stable and quick delivery to our customers worldwide.
Better material, more stable:
All our tanks are made of stainless steel, while many companies in the industry use carbon steel. Stainless steel has more stable chemical properties, which better protects the emulsion raw materials and prevents unnecessary reactions, ensuring quality right from the source.
Insulated and uninterrupted:
All our tanks have insulation layers. This means that even in winter, we can keep producing normally without any impact from the weather. Many small factories without insulation can't produce or deliver in low temperatures.
We know that caking is one of the quality issues customers care about most with RDP. We've used a whole set of measures to minimize the chance of caking:
Pre-production: Strict control on raw materials and equipment
During production: Precise process control
Temperature control is the core: Inlet air temperature precisely controlled at 170°C—the optimal drying temperature verified through repeated testing, ensuring moisture is removed evenly and thoroughly.
Post-production: Finished product handling
Premium packaging materials:
We cooperate with the same packaging bag supplier as Wacker's, so the quality is reliable and proven.
Extra protection for sea transport:
We do palletizing more carefully than others: Most only wrap film on the top and sides, but we also add a layer of cardboard and film at the bottom of the pallet. This extra "protective armor" effectively prevents goods from getting damp from the bottom in humid sea transport conditions.
Our products have already earned the trust of customers in more than 60 countries worldwide, which in itself is the best proof of our quality and reliability.
We hold ISO 9001 and EU REACH certification, and have extensive experience working with multinational corporations and top-tier factories globally.
