Import 6021e Redispersible Polymer Powder — Buy in Bulk from Supplier in China

6021E redispersible polymer powder is a water-soluble copolymer of vinyl acetate and ethylene, free of solvents and designed for polymer-modified dry mixes. Supplied as a white, free-flowing powder with a bulk density of 500 ± 100 g/l and a maximum 10% particle size over 150 µm, it forms opaque, highly flexible films with a minimum film-forming temperature of approximately 0°C and a glass transition temperature of +7°C. The product’s pH is 7.0 ± 1.0 in a 50% water dispersion, and its residual moisture content is ≤ 2%.

The powder uses polyvinyl alcohol as a protective colloid and is packaged in 20 kg valved multi-layer paper bags with a polyethylene interlayer. Typical industry standards for such powders include a shelf life of 12 months under dry conditions and compatibility with mineral binders like cement, lime, and gypsum. This grade is standard for applications requiring enhanced adhesion, workability, and crack resistance in mortars.

Common applications include EIFS adhesive mortar, plaster mortar, anti-cracking mortar, cement-based tile adhesive, tile grouts, grout mortars, repair mortar, and gypsum plaster. Buyers in construction and building material sectors source this for its ability to improve cohesion, adhesion strength, flexural strength, and crack resistance in pre-mixed mortars. The recommended dosage is a minimum of 1.5% by weight of the total dry mixture, with final dosage determined through suitability tests prior to application.

Bosson (Beijing) Chemical Co., Ltd is based in Dengzhuang West, Changping District, Beijing, China, with a registered address at 102202. The company operates as an imported-tier supplier in the chemical sector, specialising in polymer additives for construction and industrial applications. Its profile indicates a focus on providing technical-grade materials for mortar and cement modifications.

The supplier’s current trust signals include a harbor-tier verification, though its response rate is listed as 0.00 with no recorded average response hours. This suggests limited engagement via the platform, so buyers should confirm technical suitability and logistics directly with the company. The listing does not provide details on production capacity, certifications, or export markets, which buyers will need to verify independently.
