03. ROSIN ESTERS
Derived from rosin, rosin esters are compatible with a broad range of polymers such as SBR, rubbers, neoprene, acrylics, hydrocarbon resins, and alkyd resins.
They are widely used as tackifiers in various products including sealants, hotmelts, adhesives, printing ink, varnishes, and lacquers. Rosin esters are also applied in chewing gum, as well as certain food and beverages.
