Applications
PowerSorb™ 3035 is a highly effective to improve the light stability of a wide range of plastics, including styrenic polymers (ABS, ASA, HIPS, TPE’s), PVC (rigid and flexible), polyesters, polyamides, polyurethanes, and acrylics.
PowerSorb™ 3035 is also useful as a light stabilizer in adhesives and coatings applications.
PowerSorb™ 3035 is ideal for use in transparent or light-colored substrates due to its inherently non-discoloring nature. It is also non-interacting with reactive monomers (e.g. isocyanates) and metal-based polymerization catalysts. It is also suitable for use in combination with optical brighteners.
Packings
PowerSorb™ 3035 is supplied in net weight 25kg fiber drum with PE liner.
