Applications

PowerSorb™ 928 can effectively protect the coating film from light loss, cracking, blistering, delamination and discoloration.

PowerSorb™ 928 can be added to varnish, coating and solid color paint. Llight stabilizer on the surface coating has the max. protective effect.

PowerSorb™ 928 is used as light stabilizer in plastic, rubber, dye, and coating to prevent the light decomposition with long-term exposure under the sunlight.

PowerSorb™ 928 is one of substituted benzotriazoles which protect against ultraviolet radiation. PowerSorb™ 928 has high solubility which makes it particularly useful for stabilizing coatings.

Packings

PowerSorb™ 928 is supplied in net weight 25kg fiber drum with PE liner.
