  • Applications

    Tall-oil rosin (CAS 17817-95-7) is commonly used as a resin-acid based raw material for tackifiers in adhesives and sealants; it also serves as a resin component in rosin-modified alkyd and polyester coatings and varnishes; in printing inks it functions as a resin/tackifier to adjust tack and viscosity; it is a feedstock for rosin esters and derivatives that act as plasticizers or polymer modifiers in various plastics; and it can act as a sizing agent in the paper industry to impart water resistance.
