Features

Flexcon® SwitchMark® spacer components, overlaminates and laminating adhesives are specifically engineered for demanding membrane switch applications. Specially formulated pressure-sensitive adhesives are designed to bond well to a variety of surfaces. The adhesive also allows the necessary rework time to minimize waste in assembly from misaligned components.

  • Excellent high-temperature, humidity and chemical resistance which allows the switch to remain functional in extreme environments
  • Film is dimensionally stable during the conventional printing process
  • Adhesive is compatible with a wide range of solvent and UV ink systems, including conductive, decorative and dielectric inks
  • 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)
  • 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
  • Backed with a 90 lb. moisture stable polycoated layflat release liner ideal for sheet-form converting
  • Product is ideal for dome retention, tail insulating, tail reinforcing and printing conductive circuit layers
  • Product is available in rolls and sheets

Additional Details

*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 adhesive contact and improves bond strength. Always laminate to exclude air entrapment.
