Gum Rosin as a Renewable Tackifier and Resin
Gum rosin is a natural resin obtained from pine trees by tapping, comprising predominantly diterpene acids (abietic acid and its isomers). It is an important platform material in adhesives and coatings, used directly as a low-cost tackifier in rubber-based adhesives and soldering fluxes, and as the starting material for esterified rosin tackifiers (pentaerythritol and glycerol rosinate) that provide improved thermal stability and colour in hot-melt and pressure-sensitive adhesive applications.
