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 alcohol. 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
