Applications

• RIASORB® UV-120 has strong absorption near the low ultraviolet band 260nm. It has synergistic effect when combined with other antioxidant and light stabilizer, and can improve the light stability of the material.
• RIASORB® UV-120 has good compatibility with materials and does not precipitate easily. It doesn’t add any initial color to the substrate or polymer.
• RIASORB® UV-120 is particularly recommended for the use of polyolefins. The recommended dosage of RIASORB® UV-120 is 0.1-0.3%, the exact addition should be determined in trails.
