Import Compounded Light Stabilizer Uv 5151 — Buy in Bulk from Supplier in China

Compounded Light Stabilizer UV‑5151 is a liquid formulation that blends a hydrophilic 2‑(2‑hydroxyphenyl)‑benzotriazole UV absorber with a basic hindered amine light stabiliser (HALS). The blend presents as a viscous amber liquid and contains at least 93 % active ingredient by weight. Its viscosity at 25 °C does not exceed 7 000 mPa·s, while the density measured at 20 °C is 1.10 g cm‑3. These properties support its use in both waterborne and solvent‑borne exterior coating systems.

The basic HALS chemistry permits compatibility with a broad range of coating additives, and the product demonstrates a minimum transmittance of 95 % at 460 nm and 97 % at 500 nm, indicating strong UV‑blocking performance. Typical industry practice packages the stabiliser in 20 kg metal drums and stores it at 15 °C‑30 °C to preserve activity. Standard application rates fall between 1 % and 3 % of the total coating weight, delivering protection against gloss loss, cracking, blistering, delamination and colour change.

Potential buyers should request the material safety data sheet and batch analysis to verify compliance with local regulations. The supplier’s address in Guangzhou, Guangdong, places it within a major chemical manufacturing hub, though current response metrics are not disclosed on the platform. Prior to ordering, importers should negotiate Incoterms, payment terms and expected lead times directly with the supplier.

Guangzhou Chengshuai New Material Co., Ltd operates from No.10, Jiqingxiang, Shiyicun, Shilou Town, Panyu District, Guangzhou, Guangdong 511447, China. The company holds a harbour trust tier on the platform, indicating a moderate level of verification, while response rate and average response time are not published, so buyers should confirm communication reliability directly.

The manufacturer focuses on supplying additives for both waterborne and solvent‑borne coating formulations, with products such as UV‑5151 that combine UV absorbers and HALS chemistry. The listing does not disclose specific certifications, minimum order quantities or production capacity, therefore interested importers need to request these details from the supplier.
