Rosin esters

Rosin esters

Rosin esters are hard and soft resins that are produced by the esterification of monovalent and multivalent alcohols with colophonium.


Our rosin esters are primarily used as tackifiers in adhesives, to improve adhesion. Rosin esters are also used as binders in adhesives, sealants, paints and printer inks.
