Properties and uses
UV-1130 is a hydroxyphenylbenzotriazole UV absorber that effectively protects the coating from cracking and spotting. The product is easy to emulsify and is particularly suitable for aqueous systems.
The dispersion of UV-1130, an ultraviolet absorber, in aqueous systems can be obtained by dissolving it in water-soluble solvents such as diethylene glycol dimethyl ether.
UV-1130, an excellent UV absorber with high temperature and extraction resistance, is particularly suitable for industrial and automotive coatings with high weather resistance requirements. UV-1130 can also provide adequate protection to sensitive substrates such as wood.
The UV absorber UV-1130 is used in conjunction with hindered amines (HALS), such as light stabilizers 292 or 123. These co-solvent synergists can significantly improve coating performance and prevent light loss, cracking, bubbling, peeling and discoloration.
Storage conditions: should be placed in a dark, well-ventilated place, keep dry, do not directly exposed to sunlight.
