UVINUL 3049
UVINUL 3049
UVINUL 3049 is an efficient UV absorber for polyester film, which it protests from premature damage, particularly under severe exposure conditions. The polyester film can be treated by applying a hot solution of UVINUL 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:
- 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 fibers in the dye bath)
- Photographic emulsions
- Acrylic resins
- Alkyd resins
- Epoxy resins
- Cellulose nitrate
- Phenolic resins
- Fluorescent pigments
- PUR systems
- Oil paints
- Polymer dispersions
