　　Characteristics and uses UV-1130 is a benzotriazole ultraviolet light absorber used in the coating industry. This product is easy to emulsify, especially suitable for water-based systems. UV-1130 with high temperature resistance and anti-extraction characteristics can be very competent Automotive paints, industrial paints and other fields that have higher weather resistance requirements can also provide sufficient protection for light-sensitive substrates such as wood. In the toluene solution, the cell thickness is 1 cm, and the maximum absorption wavelength is 346 nm.

　　The use of UV-1130 in combination with hindered amine light stabilizers UV-144, 292, or UV-123 will significantly improve the weatherability of the coating. The synergistic effect will make automotive coatings play a better role, and it has a good inhibitory effect on matt, crack, blistering, shedding and discoloration. Users should get the best results and additions through a series of experiments.

　　Recommended dosage (relative to resin solids): 1-3% UV-1130; In addition, 0.5-2% UV-292, UV-144 or UV-123 can be added.

　　Storage and packaging As an industrial chemical, UV-1130 should strictly abide by the precautions: avoid contact with the skin, and wear an eye mask to avoid eye irritation. The product should be stored in a cool and dark place and sealed after use. For more information, please refer to the UV-1130 Safety Data Sheet.
