Hydrogenated resin
Key properties
Staybelite A is a pale, thermoplastic, acidic resin with similar properties 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.
- Tackifier, plasticizer, and processing aid for polymers in hot melt coatings and adhesives
- Component in thermoplastic mixtures for can sealing compounds, sealing wax, optical lens pitch, and electrical cable saturants
- Wax modifier in paper coatings for enhanced gloss, clarity and adhesion
- Used in preparations of synthetic resins, metal resinates, soldering fluxes, caulking compounds and ceramic inks
- Exceptional pale color
- Resistant to oxidation and discoloration
- Wide solubility and compatibility range
