China RDP Powder Supplier | LANDU VAE Redispersible
Polymer Powder

Q: 2. What makes LANDU's storage tanks superior to industry standards?

Etter 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.

Types of ACCURATE Redispersible Polymer Powder

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.

Rigid Redispersible Polymer Powder

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

Flexible Redispersible Polymer Powder

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

Leveling Redispersible Polymer Powder

Best for: Self-leveling mortar applications

LANDU ACCURATE Leveling RDP powder maintains mortar flowability while improving:

Hydrophobic Redispersible Polymer Powder

Best for: Moisture-exposed projects

Our hydrophobic Redispersible Polymer Powder resists:

Applications of Redispersible Polymer Powder

Self-Leveling Compounds

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.

EIFS (Exterior Insulation and Finish System)

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.

Tile Adhesive

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.

Wall Putty/Skim Coat

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.

Waterproof Mortar

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.

FAQs - China RDP Powder Supplier LANDU

Everything you need to know about LANDU's RDP production and quality control

1. How does LANDU ensure fast delivery even during supply chain challenges?

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.

2. What makes LANDU's storage tanks superior to industry standards?

Etter 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.

3. How does LANDU ensure packaging quality 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.

4. What are LANDU's core equipment advantages?

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

Precision filtration:14 precision filters remove all impurities before drying

Ultra-high-speed atomizer:15,000 RPM ensures uniform fine droplets, eliminating oversized particles

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

Forced cooling:Special cooling device brings temperature down before packaging to prevent moisture absorption

Secondary sieving: Two layers of vibrating screens remove any possible impurities or agglomerates
