Description

Benzophenone-6, also known as UV Absorber BP-6, 2,2'-Dihydroxy-4,4'-dimethoxybenzophenone, is a benzophenone ultraviolet absorber. Benzophenone-6 is insoluble in water, soluble in organic solvents such as toluene, methanol, ethanol, etc. It has the advantages of light color, non-toxic, good compatibility, small migration, easy processing and so on. Benzophenone-6 can effectively absorb ultraviolet light in the wavelength range of 270 ~ 400nm. It is especially suitable for the production of light-colored and transparent fabrics. Its light, heat and chemical stability are better than benzophenone-3. It has the greatest protection for the polymer and helps reduce color, while delaying yellowing and blocking the loss of physical properties. Benzophenone-6 is widely used in PE, PVC, PP, PS, PC and other materials. Benzophenone-6 provides good light stabilization for dry phenolic and alkyd varnishes, polyurethanes, acrylics, epoxy and other air-drying products and automotive finishing paints. Benzophenone-6 is also used in resin lenses, solar films, stickers, high-end cosmetics, new high-end coatings, paints and fabrics.
