SONGWON launches new UVA SONGSORB® CS 400

SONGSORB® CS 384-2

ONGWON is expanding its range of ultraviolet absorbers well as both wood and plastic substrates very efficiently
S(UVAs) for high performance coatings and is now against ultraviolet radiation. Outstanding thermal stability
launching two new products, SONGSORB® CS 400 and and resistance to environmental impacts make it an
SONGSORB® CS 384-2. The two UVAs can both be used in excellent choice for coatings exposed to high bake cycles
combination with a hindered amine light stabilizer (HALS) and/or extreme weather conditions. With its liquid form,
such as SONGSORB® CS AQ01, which was introduced SONGSORB® CS 384-2 is suitable for incorporation in
at this year’s European Coatings Show. “The new UVAs waterborne and in most common solvent systems.
provide coatings with outstanding protection against Both SONGSORB® CS 400 and SONGSORB® CS 384-2 can be
degradation due to high temperatures during processing
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.

SONGWON. SONGSORB® CS 400 is a liquid hydroxyphenyl multilayer rotomolded parts, the TCN Rotoline. TCN
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
