ECOTACK® 1301 is a polymerized gum rosin. Polymerization is a chemical reaction in which a part of the abietic acid present in the gum rosin is converted to a dimer, by linking two molecules of it. This reaction leads to the polymerized gum rosin. Compared with ordinary gum rosin, a 20-25ºC raise in the softening point can be achieved.
