EVALUATION OF THREE METHODS OF APPLYING ' 'SCOTCHCAL' ' TO ALUMINIZED LACQUERED SURFACES.
Abstract
Peel strength specimens were prepared to compare the adhesion of the Scotchcal to alodined aluminum, zinc chromate primed, and aluminized lacquered surfaces. Two lacquers, MIL-L-7178 aluminized lacquer and color 16473 lacquer, were used. The highest average peel strengths (9.0 lbs per in.) were obtained from the specimens that had been prepared by applying the Scotchcal directly to the aluminized lacquer, after the lacquer had dried 8 to 24 hours. The lowest average peel strengths (5.5 pounds per in.) were obtained from the specimens that had been prepared by applying the Scotchcal either to the alodined aluminum or to the zinc chromate primed surfaces.
