Partially hydrogenated gum Rosin has a lighter color and is more stable.
Hydrogenated rosin has more resistance to oxidation and has lighter color.
Like unmodified pine rosin, hydrogenated rosin have a wide span of compatibility with almost all polymers. They are well known for their peel and tack contribution to the adhesive. Specific benefits of hydrogenated rosin include:
Lighter color.
Significantly improved stability.
Less to no skin sensitization (depends on the degree of hydrogenation).
Less UV absorption, thus making them suitable for UV curable polymer based adhesives.
Imparts only a slight decrease of cohesive strength, especially in block co-polymer systems.
Can be used in amorphous polyolefin based adhesives.
CAS Number: 65997-06-0

Caution:
Hydrogenated Rosin has been found to have less skin sensitization than unmodified pine rosin, but caution should still be exercised when handling it. Always wear appropriate protective equipment when working with Hydrogenated Rosin or any other chemicals.
Perfect for adhesives manufacturers and industrial users who require a high-performance adhesive enhancer with improved stability and lighter color.
Staybelite® Ester 10 is the glycerol ester of partially hydrogenated wood rosin. It is a pale, thermoplastic resin with excellent resistance to oxidation and discoloration. It has found wide acceptance as a tackifying resin for many adhesive applications, particularly pressure sensitive and emulsion types. In general, it is useful where there is need for pale, nonoxidizing, and color stable resin.
Applications
- Used in solvent, hot melt, and emulsion adhesives based on thermoplastic and elastomeric materials
- Tackifier in emulsion form for natural rubber, SBR, and neoprene latex in aqueous base adhesives
- Tackifier for natural rubber, SBR, polyisobutylene, and methacrylate resins in industrial tape uses
- Tackifier for surgical tape and in EVA resin-based hot melt adhesives
- Hot melt applied barrier coatings, chlorinated rubber finishes, and various protective coatings compositions
- Component of depilatory wax compounds
Benefits
- Pale
- Tacky
- Oxidation resistant
- Emulsifiable
- Wide range of solubility and compatibility
- Broad regulatory approval
