UV Linsorb 531
|Appearance||slightly yellow powder|
|boiling point||> 300°C|
>Features of uv 531 are low yellowing, good absorbance in the UV-B region, improves failure of coatings resulting from exposure to sunlight including discoloration, cracking and loss of adhesion. Used as Chimassorb 81 equivalent.
>UV 531 is a UV absorber for plasticized and rigid PVC, polyester, PS, Acrylate resins, vinyl ester based coatings, PU based coatings, alkyed resin coatings, improves the weather resistance of the coating.
>Its performance in outdoor applications can be improved further by use in synergistic combination with a hindered amine light stabilizer (HALS) such as HALS 292.
>The amount of UV 531 required for optimum performance should be determined in trials covering a concentration range.
Handing and Safety:
>FDA approves, under the 21CFR178.2010 for use in aqueous foods, dairy products (water-in-oil emulsions), bakery products without oil, and dry foods without oil at a maximum concentration of 0.5%.
>For additional handing and toxicological information, please consult us for Maternal Safety Date Sheet.
