Features & Benefits

  • High-performance permanent pressure-sensitive acrylic adhesive bonds well to high-surface energy plastics, metal and paint*
  • Superior mechanical properties ensure long-term membrane switch performance without delamination (ASTM F 1578-00)
  • Adhesive offers excellent high-temperature, humidity and chemical resistance
  • Product can be repositioned within the first few minutes of application allowing easy correction of assembly mistakes
  • Adhesive is compatible with a wide range of solvent and UV ink systems, including conductive, decorative and dielectric inks
  • 80 lb. backside branded bleached polycoated mando release liner on one side
  • SwitchMark® branded, color-coded (blue) release liner ensures easy product identification and mistake proofing during production and switch assembly
  • Backed with a 90 lb. moisture stable polycoated layflat release liner ideal for sheet-form converting
  • Moisture stable, layflat release liner is ideal for sheet-form converting
  • Product is available in rolls and sheets
  • Product is RoHS compliant
  • Adhesive system has UL recognition under UL746C, Polymeric Adhesive Systems, Electrical Equipment - Component and UL969, Marking & Labeling Systems Materials Component 302°F (150°C)

*Recommendations: Application surfaces must be above 50°F (10°C). Surfaces must be clean and dry to obtain best adhesion results. Firm and even laminating pressure helps promote better adhesive contact and improves bond strength. Always laminate to exclude air entrapment. When diecutting, the 80 lb. printed mando liner should be used as the diecutting base.
