Material Notes:

A truly unique, two-component, room temperature curing thixotropic epoxy adhesive system, which exhibits good bond strength at service temperatures up to 400°F. Ideal for applications where resistance to high service temperatures is required, but where a room temperature cure is desirable.Information provided by Ellsworth Adhesives.
