Hydrogenated resin

Foral 3085

Foral® 3085 resin is a glycerol ester of highly hydrogenated rosin.

Key properties

Similar to, but less refined than, Foral 85 resin, it is indicated for use in a wide array of adhesive tackifier applications where light color and oxidation resistance are needed.

Applications

Tackifier or modifier for adhesive systems, including:

  • Hot melt
  • Pressure sensitive
  • Solvent
  • Emulsion
  • Sealant compounds

Modifier in protective or barrier coatings

Component of thermoplastic compounds and hot melt depilatory waxes

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.
