The SElf-siickiNq qAsker: TIIE qluE qoEs iN \\ NOT ON Now you can put the glue in the gasket. So your customer doesn't have to put glue on it. Or on the mirror. Or on anything else. You can make a self-gluing gasket from a vinyl plastisol by adding an Eastman plasticizer adhesive instead of just a plasticizer. Put the gasket on a bare or coated metal substrate. Heat it, and it sticks. Without glue. With bond strength often greater than the cohesive strength of the vinyl itself. Plasticizer adhesive PA-3 has an exceptionally low activation temperature. It's high-solvating. And it gives excellent viscosity stability with homopolymer resins. Low-solvating PA-5 has a slightly higher activation temperature. But it's less expensive than PA-3. And it prevents bleed-through when vinyl dispersions are top-coated with conventional finishes. Try PA-3 and PA-5 in automotive and appliance sealants. In structural adhesivesfor metal fabrication. In dip coatings. In foamed and unfoamed insulation. For more information on PA-3, ask for Data Sheet X-210. For more on PA-5, ask for X-209.
