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.

ECOTACK^® 1001 is gum rosin from “P.elliottii” and it is produced in a highly controlled process with selected raw materials, so resulting in a very clear and uniform product.
