Terpene Phenolic Resins
The major use of terpene phenolic resins is in the feld of adhesives. The use of
terpene phenolic resins will improve the adhesion of hot-melt packaging and
pressure sensitive adhesives to substrates like coated and recycled paper, glass and
metal foils that are typically tough to bond to. Terpene phenolics are often used in
combination with a heat reactive resin to gain a balance of properties. Their function
in a resin system is to increase the open time and tack of the adhesive. Akrochem’s
terpene phenolic resins for this application and others like it are as follows:
SP-560 (P-03)
SP-560 is a thermoplastic, oil-soluble, terpene phenolic resin. This resin is used
mainly in adhesives as either the base resin or as a modifying resin in the formulation
of polychloroprene cements. It can also be used in hot-melt or solution adhesives
made from other elastomers where the combination of high tack and high heat
performance is desired. To improve the high temperature performance of cements,
SP-560 may be blended in any proportion with heat reactive resins. The heat
resistance of the adhesive formulation will increase along with the percentage of
heat reactive resin, but this will be gained at the expense of decreasing open time.
