Silicone pressure sensitive adhesives (PSA) for papers and films

Pressure sensitive adhesives are able to provide measurable adhesion to a given surface simply upon contact or by the application of light pressure. Silicones for pressure sensitive adhesives serve many applications such as adhesive tapes for electrical insulation, masking tape to protect circuit boards, protective films for for displays and electronic touch screens and many more markets as the electronics industry keeps developing. Silicone pressure sensitive adhesives are available in both solvent and solvent-free technologies while new technologies like water-based and UV are expected to grow in the future with new electronic applications. 

The Silcolease™ PSA product line supports the industrial and consumer electronic applications and is designed to offer a wide choice of tack and peel adhesion options which are compatible with many substrates and resistant over a range of temperatures that make them suitable to all kind of climates and environments:

  • Low tack and low peel adhesion for your television, mobile screens protection during transport
  • High tack and high peel adhesion for your permanent protection films during mobile display daily use
