QUESTION: We are manufacturers of steel toecaps for safety footwear. We need to apply a PVC strip with an adhesive to the back edge of the toecap to prevent the cap's back edge from cutting through the finished shoe. Our problem has been that the cap is treated with a rust preventative that is a 5% oil-in-water emulsion. The rust preventative is needed to meet a corrosion requirement of an ASTM standard, but we haven't been able to find a quick-acting adhesive that will bite through it and give us a good bond. Can you recommend anything?
