Songwon Industrial Co Ltd has launched two new products, SONGSORB CS 400 and SONGSORB CS 384-2, expanding its range of ultraviolet absorbers (UVAs) for high-performance coatings.
The two UVAs can both be used in combination with a hindered amine light stabilizer (HALS) such as SONGSORB CS AQ01.
SONGSORB CS 400 is a liquid hydroxyphenyl triazine (HPT) UV absorber with very high thermal stability and outstanding resistance in coatings exposed to high bake cycles and/or extreme external conditions. With its hydroxy functionality, SONGSORB CS 400 minimizes migration and provides coatings with high photostability for long-term performance.
The molecule is designed to ensure high performance and durability in water- and solvent-borne as well as 100 percent solids automotive and industrial finishes. Its colour and stability make SONGSORB CS 400 the UVA of choice for all coatings that require low colour. It is suitable for use in amine and/or metal catalyzed coatings and coatings applied on basecoats or substrates containing such catalysts because it does not interfere with them.
