Applicable Base Polymer Properties

Films are blends containing 30-50% by weight of epoxy resin. The nylon constituent provides high tensile shear strength as well as high peel strength. Suitable catalysts are dicyandiamide and aromatic polyamines. These adhesives have useful properties at low temperatures but have only moderately good high temperature properties.

Resulting Properties

The table above shows a starting formulation for epoxy nylon adhesives. It can be formed into a film by casting from a solvent or by melt extrusion. Cure conditions are 60 min at 163°C. Resulting adhesive will have a peel strength of 60-80 piw and a shear strength of 6200-6600 psi at room temperature.
