Advantages compared with domestic products:

1) lighter in color.

2) higher content

3) less solvent

Application: as uv stabilizer, it is mainly used in polyurethane, PVC, propylene resin, polyester, etc.

UV - 1 can effectively prevent the two-component polyurethane coatings, polyurethane soft foam and polyurethane thermoplastic elastomer polymer such as yellow, can effectively inhibit photocatalytic degradation of polymers, enhance the color stability of the products, prolong service life, especially in the polyurethane products such as microcellular foam, foam whole skin, and the traditional hard bubble, semi-hard foam, soft foam and fabric coating, sealant and elastomer, certain adhesives and polyvinyl chloride (PVC), acrylic acid resin has excellent light stability of polymer.

Usage: uv-1 has high solubility in various solvents and good compatibility with other polyurethane additives. Its UV resistance is 1.1-1.4 times of that of dibenzophenone or benzotriazole.

The normal dosage of uv-1 in polyurethane ranges from 0.3% to 0.5%.
