FloraRez® DR140

1 of 11 products in this brand
FloraRez® DR140 is a polymerized rosin that is produced through the partial dimerization of gum rosin using a catalytic process. This results in a resin with a high dimeric acid content and a very high softening point, while still maintaining the acid functionality of rosin. FloraRez® DR140 is pale, thermoplastic, crystallization-resistant, and less prone to oxidation compared to unmodified rosin. Its high acid functionality promotes specific adhesion to a wide range of substrates.
