Songsorb CS 400 and Songsorb 384-2

Protection against Degradation

Songwon, Ulsan, South Korea, is expanding its range of ultraviolet absorbers (UVAs) for high performance coatings and is now launching two new products, Sonsorb CS 400 and Songsorb CS 384-2. The new UVAs provide coatings with outstanding protection against degradation due to high temperatures during processing and environmental impact during use. They therefore help to prolong the life of end products such as vehicles, according to the manufacturer.

SongsorbCS 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% solids automotive and industrial finishes. Its color and stability make Songsorb CS 400 the UVA of choice for all coatings that require low color. 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.

Songwon is also complementing its existing liquid benzotriazole range of UVAs. Songsorb CS 384-2 is designed for high performance coatings that meet the durability requirements of automotive coatings and provide top quality finishes. It protects base coats as well as both wood and plastic substrates very efficiently against ultraviolet radiation. Outstanding thermal stability and resistance to environmental impacts make it an excellent choice for coatings exposed to high bake cycles and/or extreme weather conditions. With its liquid form, Songsorb CS 384-2 is suitable for incorporation in waterborne and in most common solvent systems.

Both new UVAs can be used in combination with a HALS such as Songsorb CS 292 or Songsorb CS AQ01 to obtain synergistic effects that protect coatings still better against gloss reduction, cracking, blistering, delamination and color change.
