Features and Applications

UV-1130 is a kind of benzotriazole UV absorber used in paint industry. This product can easily emulsify, especially suitable for water soluble systems. UV-1130 has the properties of high temperature resistance and extraction resistance, and is very competent to high weather resistant fields such as automobile paint, industrial paint. In addition, it can perfectly protect light sensitive base materials such as wood. In toluene solution, depth 1cm, the maximum absorption wavelength is 346nm.  
UV-1130 can be used in combination with a hindered amine light stabilizer (HALS) such as LS 292. These synergistic combinations impart superior paint protection against gloss reduction, cracking, blistering, delamination and color change.
The dosage is recommended to be 1.0%~3.0% (based on solid resin weight).
In addition 0.5-2% LS 292 can be added.
