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 Physical Properties of PowerSorb™ 3049 CAS No. 131-54-4 Appearance Pale Yellow Powder Density [25°C, g/cm3] 34 Melting Point (°C) 129-139 Volatile (%) Max.2.00 K Value Min.49.00 Purity (%) Min.94 Solubility of PowerSorb™ 3049 CAS No. 131-54-4 Solubility [20°C] % w/w Methanol <1 Ethyl acetate 5 Methyl ethyl ketone 5 Toluene 5 Water <0.01 There are many bulk chemical companies, but we are one of the best choices for you.
