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.
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.
• 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.

We specialize in supplying artists' materials that were used in historical painting since pre-historic times up to and including the nineteenth century.
We constantly search for materials and products of the finest quality so that we can bring them direct to you from the source. To do so, we travel the world to find materials specifically for use by professional artists and decorators. We obtain minerals from mines in Afghanistan, Chile, Russia, Ukraine and Uzbekistan, to name a few places, processing these into natural pigments. We purchase resins, gums and plants from India, Kenya and Malaysia to make natural varnishes and painting mediums.
Our mission is to provide the largest variety of natural pigments, paints and other professional artists' supplies, enabling us to bring you a selection that makes shopping for rare and hard-to-find art materials easy.
