EXTON, Pa. -- Global specialty chemicals manufacturer Sartomer
USA, LLC now offers CN9026, a highly functional aliphatic urethane acrylate that
demonstrates outstanding weatherability in exterior hard coat applications compared to
traditional urethane acrylates. This oligomer is well suited for coatings used on
automotive finishes, auto accessories made of plastic or metal and window films for
automotive and structural applications. Its scratch resistance also makes it suitable for
sensitive electronic devices and their component parts.
CN9026 is a clear liquid oligomer that has high hardness, high scratch resistance and
excellent resistance to yellowing.
It offers lower crosslink density than other highly functional urethane acrylates and is,
therefore, more flexible at higher coat weights. For example, testing showed that a 10-
micron coating was completely immune to 5,000 hours of QUV accelerated weathering
exposure, showing no signs of cracking. A similar thickness industry standard urethane
failed the same test after just 1,000 hours.
