Hydrogenated resin
Key properties
Foral 85 resin can be used as a tackifier resin in various types of adhesives, and in protective and barrier type coatings that require an exceptional degree of color retention and oxidation resistance.
It is particularly effective in tackifying acrylic PSA formulations.
- Tackifier resin for pressure sensitive adhesives used for tapes, labels, medical appliances, and specialty applications
- Tackifier resin in lamination of metal foil, paper, cloth, cellophane, and cellulose acetate films
- Imparts hot tack and heat sealability in hot melt adhesives and improves adhesion to substrates
- Improves hot tack and bond strength in hot melt coatings
- Improves surface gloss and clarity in packaging appearance
- Increases gloss, transparency, and adhesion as a modifier in paraffin wax
- Resistant to oxidation
- Pale color
- Excellent color retention
- Inherent tackiness
- Extensive solubility and compatibility
- Low odor

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 resin 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 given to minimize opportunities for product oxidation throughout processing.
Accordingly, it is strongly recommended that proper storage conditions and strict control of inventory be observed at all times, taking care that the oldest material is used first.
