Anchor Chemical Group PLC (a wholly owned subsidiary of Air Products PLC) has found that use of its Amicure PACM curing agent in heat‐cured, two component adhesives greatly increases the adhesive's high‐temperature performance for plastic or metal bonding. Partial substitution of Amicure PACM curing agent for a standard, high‐imidazoline polyamide in typical adhesive formulations can increase lap shear strength by up to 60 percent. In addition, testing to determine the mode of failure when bonding plastic substrates confirmed the performance benefits of including Amicure PACM curing agent in the adhesive formulation.
