Adhesives and Epoxies Q&A
-
We need to bond a Mylar film with a PET backing to extruded ABS sheeting. We are looking for a liquid and/or PSA. The criteria we need to achieve are adhesion for a period exceeding five years, the finished product will be in high humidity environments and exposed to fresh/salt water spray, and the temperature will vary from –20° to 180°F (or very close to that).Answered December 14th, 2010 by Expert:A silicone sealant/adhesive (Pt curable) or silicone pressure-sensitive/lamination adhesive would be good options to evaluate. A PSA such as Dow Corning’s Q2-7406 (solvent based, peroxide cure) would be applied to the Mylar film using a drawdown bar or Mayer rod. The solvent would be driven off at 65°C for 2 minutes, and then the PSA would be cured at 150°C for 2 minutes. Then the ABS would be applied.
You could also devolatilize the solvent, apply the film and uncured PSA to the ABS, and then cure at 150°C in more of a lamination-type application. If a lower temperature is required, platinum curable DC 7657 and Syl-Off 4000 catalyst could be mixed and then cured between 80° and 130°C (after driving off the solvent).
For a solvent-free option, DC 2013/Syl-Off 4000 would be a good option.
