Hydrogenated resin

Staybelite Ester 10

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

Key properties

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

Staybelite Ester 10 has found wide acceptance as a tackifier resin for many adhesive applications, particularly pressure-sensitive and emulsion adhesives.

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


  • 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 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.
