Staybelite® A

Staybelite® A resin is gum rosin that has been partially hydrogenated via a catalytic process. It is a pale, thermoplastic, acidic resin, and has similar characteristics to Staybelite hydrogenated wood rosin. Hydrogenation makes this resin highly resistant to oxidation and discoloration, and to changes in solubility characteristics, when it is exposed to air and heat. In these respects, it is greatly superior to ordinary non-hydrogenated rosins. Esters, metallic salts, and other derivatives of Staybelite A resin inherit this stability to a large degree.
