Some Effects of Curing Conditions on Adhesion to Metal Surfaces

The effect of curing temperature on the peel strength of three different adhesive systems is reported. The adhesive systems were cured at 250 F, 275 F, 300 F, 325 F, and 350 F on aluminium, stainless steel, and titanium surfaces. The adhesives were also subjected to a single and a double cure cycle on four different aluminum alloys. Peel strength was determined at ambient temperature and at -67 F.
