Similarly films with or without primers, like polyester/polypropylene/PE (polyethylene)/HDPE (high density polyethylene) etc are also used for silicon coating.

  • Adhesive materials used in this invention and which are also referred to as Pressure- sensitive adhesive are adhesive which forms a bond when pressure is applied to the adhesive with the adherend. It is used in pressure-sensitive tapes, labels, glue dots, note pads, automobile trim, and a wide variety of other products. As the name "pressure-sensitive” indicates, the degree of bond is influenced by the amount of pressure which is used to apply the adhesive to the surface. Surface factors such as smoothness, surface energy, removal of contaminants, etc. are also important to proper bonding. PSAs are usually designed to form a bond and hold properly at room temperatures. PSAs typically reduce or lose their tack at low temperatures and reduce their shear holding ability at high temperatures; special adhesives are made to function at high or low temperatures. It is important to choose an adhesive formulation which is designed for its intended use conditions.
