Hydrogenated resin

Staybelite Ester 10 A

Staybelite Ester 10 A rosin is the glycerol ester of partially hydrogenated rosin.

Key properties

This is a pale, thermoplastic rosin with excellent resistance to oxidation and discoloration.

It is recommended for use as a tackifier resin for many adhesive applications, particularly pressure-sensitive and emulsion types.

In general, it is useful where a pale, nonoxidizing, and color stable resin is required.

Applications

  • Used in solvent, hot melt, and thermoplastic and elastomeric material-based adhesives
  • Tackifier in emulsion form for natural rubber, SBR, and neoprene latex in aqueous base adhesives
  • Tackifier for natural rubber, SBR, polyisobutylene, and methacrylate resins used in industrial tape
  • Tackifier for surgical strips and EVA resin-based hot melt adhesives
  • Hot melt applied barrier coatings, chlorinated rubber finishes, and various protective coating compositions
  • Component in depilatory wax compounds

Pastillated or flaked resins may fuse, block, or lump during hot weather months, if stored near sources of heat, if double or triple stacked, or if stored for prolonged periods of time.

These forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents.

Care should be taken to minimize opportunities for product oxidation throughout processing. Accordingly, we strongly recommend maintaining proper storage conditions and strict inventory control at all times, ensuring that the oldest material is used first.
