Applications

• RIASORB® UV-292 is a high-effective liquid HALS (Hindered Amine Light Stabilizer), with low volatility and high thermal stability. It protects coatings from gloss reduction, cracking and delamination.
• RIASORB® UV-292 is suitable for a wide range of coatings, like wood coatings, industrial and automotive coatings. Synergistic performance can be obtained when used with an UV absorber. RIASORB® UV-292 may crystallize during storage below 0℃, however the product can be easily liquefied by warming.
