SP-154 (P-105)
SP-154 is a heat reactive phenolic resin that was developed for the formulation of solvent-
borne polychloroprene contact cements. It can also be used in formulating adhesives
with NBR, SBR, Natural and reclaimed rubbers. SP-154 is completely compatible with NBR
and CR. It has a compatibility limit of approximately 25 parts by weight in combination
with 100 parts by weight of SBR, Natural and reclaimed rubbers. Adhesives made using
SP-154 have excellent heat resistance, high cohesive strength and light color.
FRJ-551 (P-126)
FRJ-551 is a heat reactive alkylphenolic resin which is designed primarily for use
in the formulation of polychloroprene-based contact adhesives. In adhesives
based on polychloroprene, FRJ-551 gives good bond strength, both at room and
elevated temperatures.
HRJ-1367 (P-148)
HRJ-1367 is an oil soluble, heat reactive, phenolic resin based on a para-substituted
alylphenol. It is used in the formulation of polychloroprene contact cements with good
green strength and heat resistance. The outstanding features of this resin are its high
reactivity, narrow molecular weight and light color. It can also be used in formulating
adhesives with NBR, SBR, Natural and reclaimed rubbers. HRJ-1367 is completely
compatible with NBR and CR. It has a compatibility limit of approximately 25 parts by
weight in combination with 100 parts by weight of SBR, Natural and reclaimed rubbers.
