Interpreting Cure

After surface is thoroughly cleaned, apply a film of adhesive. Film thickness depends upon the users needs, but should not exceed 4 mils. After exiting the curing unit, the adhesive should appear clearer (less amber and haze). Apply the substrate (with the cured adhesive already applied) to a solid surface and pull the substrate back onto itself. If the adhesive appears smudgy or sticky, the adhesive is under-cured. If, on the other hand, the adhesive has short stumps of adhesive that appear rubbery, the adhesive is correctly cured.
