ULSAN, SOUTH KOREA: 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.

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 SONGSORB CS 400 and SONGSORB CS 384-2 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 colour change.

“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,” said Rosanna Telesca, leader, market centre coatings at Songwon.
