Export-Grade RDP Powder | Stable Redispersible Latex Powder KINGMAX Manufacturer


Post time: Sep-17-2026

For overseas importers and dry-mix mortar manufacturers, stable raw material quality and complete export supporting documents are two core requirements when sourcing construction chemicals. KINGMAX export-grade RDP powder is specially produced as redispersible latex powder complying with international trade standards. Manufactured by spray drying VAE polymer emulsion, our export RDP maintains steady redispersion and film-forming properties batch after batch, meeting the strict demands of global dry mortar production.

KINGMAX is a professional Chinese manufacturer of cellulose ether and redispersible polymer powder. Our export-grade RDP series has been widely shipped to many countries and regions, serving customers who produce tile adhesive, EIFS thermal insulation mortar, wall putty, gypsum plaster, self-leveling mortar and repair mortar.

Core Characteristics of KINGMAX Export-Grade RDP Powder

  • Stable redispersibility: Quickly re-disperses into uniform polymer emulsion once mixed with clean water, no hard agglomerates.
  • Reliable film-forming performance: Forms continuous elastic polymer film after curing, delivering stable bonding, flexibility and crack resistance.
  • Consistent batch indicators: Every lot is tested for fineness, ash content, tensile adhesion and elongation to avoid performance fluctuation.
  • Good compatibility: Works perfectly with cement, gypsum, quartz sand, HPMC and other common dry mortar additives.
  • Low caking risk: Optimized powder particle structure plus moisture-proof packaging for long sea transportation.

Main Functions of Export-Grade RDP in Dry-Mix Mortar

  1. Improve tensile and shear bonding strength between mortar and various substrates.
  2. Increase flexibility and crack bridging ability to resist shrinkage and thermal stress.
  3. Enhance water resistance, freeze-thaw stability and long-term weatherability for exterior mortar.
  4. Boost surface toughness and abrasion resistance of wall putty, gypsum plaster and flooring mortar.
  5. Adjust rheology of fresh mortar, improve anti-sag performance and extend open time for construction.

Application Range of Export-Grade RDP Powder

  • Tile adhesive & tile grout: C1, C2 and flexible C2TES1 tile adhesives for interior and exterior tiles
  • EIFS external insulation mortar: Base coat and finishing mortar for EPS / XPS boards
  • Wall putty: Interior leveling putty and exterior weather-resistant putty
  • Gypsum products: Gypsum plaster, gypsum joint filler and gypsum repair compounds
  • Self-leveling floor mortar: Cement and gypsum self-leveling underlayment
  • Repair mortar and cement-based waterproof mortar

Export Packaging & Shipping Solution

KINGMAX export-grade RDP adopts 25kg moisture-proof paper bags with inner PE liner. All bags are stacked on standard export pallets and wrapped with stretch film, preventing moisture, friction damage and pallet collapse during long ocean transit.

We support FCL full container orders. Mixed container loading is available if customers order RDP together with our HPMC, MHEC or HEMC cellulose ether, helping you save ocean freight and simplify procurement.

Complete Export Documents

For every shipment, we prepare full set of export papers for customs clearance: COA (Certificate of Analysis), TDS (Technical Data Sheet), MSDS (Material Safety Data Sheet), commercial invoice, packing list and bill of lading related supporting files. We can cooperate with third-party inspection upon customer request.

  1. Export-oriented production line, strict quality control for cross-border shipment.
  2. Stable batch-to-batch consistency to avoid finished mortar quality fluctuation.
  3. Professional export team with rich experience in handling international logistics and documentation.
  4. Factory direct price, no middle traders. Competitive cost advantage for bulk orders.
  5. Free test samples and professional technical support for dry mortar formulation.
  6. One-stop supply: RDP plus full series cellulose ether additives.

Recommended Dosage Reference

  • Interior wall putty: 0.8%–1.8%
  • Exterior wall putty: 1.5%–2.5%
  • Tile adhesive: 2.0%–4.5%
  • EIFS base coat mortar: 2.5%–3.8%
  • Gypsum plaster:1.0%–2.2%
  • Self-leveling mortar:1.8%–3.2%

Formulation tip: Combine export-grade RDP with suitable HPMC cellulose ether. HPMC provides water retention and construction workability; RDP improves cured mortar strength, flexibility and durability. Mix all dry powders homogenously before adding water.
