PowerSorb™ 3049 is an efficient UV absorber for polyester film, which it protests from premature damage, particularly under severe exposure conditions.

Technical Data of PowerSorb™ 3049 cas 131 54 4

Benefits & Applications of PowerSorb™ 3049 CAS No. 131 54 4

The polyester film can be treated by applying a hot solution of PowerSorb™ 3049 in a polyhydric . The transmittance of film treated in this manner is greatly reduced for light of wavelengths less than 400 nm, thus allowing the film it to be used as a UV filter.

Other fields of application are:

– Allyl carbonate (spectacle lenses, 0.3 %)

– Rubber

– PUR furniture paints and varnishes (0.50 - 1.00%)

– Textile industry (as a light stabilizer that is taken up by the fibres in the dye bath).

– Photographic emulsions

– Acrylic resins, Alkyd resins, Epoxy resins, Phenolic resins

– Cellulose nitrate

– Fluorescent pigments

– PUR systems, Oil paints, Polymer dispersions
