Gum Rosin (Staybelite A) 500g
Staybelite A resin is gum rosin that has been partially hydrogenated. It is a pale, thermoplastic, acidic resin. Hydrogenation makes rosin highly resistant to oxidation and discoloration, and to changes in solubility, when exposed to air and heat.
Staybelite A resin is gum rosin that has been partially hydrogenated via a catalytic process. It is a pale, thermoplastic, acidic resin. Hydrogenation makes rosin highly resistant to oxidation and discoloration, and to changes in solubility, when exposed to air and heat. In these respects, Staybelite A is greatly superior to non-hydrogenated rosin. Metallic salts and other derivatives of Staybelite resin inherit this stability to a large degree. The softening point of Staybelite resin is slightly lower than that of non-hydrogenated rosin; otherwise, its solubility and compatibility characteristics are similar to rosin.
Benefits
Staybelite A is superior to gum rosin in that it has exceptionally pale color, is resistant to oxidation and discoloration, and has a wide solubility and compatibility range greater than ordinary non-hydrogenated rosin.
Applications
• Component in thermoplastic mixtures for polishing wax, sealing wax and encaustic wax.
• Used in the preparation of synthetic resins and metal resinates.
• Used in most applications where gum rosin is used.
