P-148 Resin is an oil-soluble, heat-reactive, phenolic resin based on a para-substituted alkylphenol. 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. P-148 is used in high performance polychloroprene contact cements and pressure sensitive adhesives. It is completely compatible with polychloroprene and NBR. It has a compatibility limit of approximately 25 parts by weight in combination with 100 parts by weight of SBR, natural and reclaimed rubbers. P-148 imparts good green strength, extends open tack time, increases heat resistance, increases specific adhesion of the film to metal and glass, and increases the cohesive strength of the adhesive film itself.
