ABSTRACT:
A tape backing comprised of a siliconized epoxy resin reinforced with a polyester or polyamide non-woven fabric is described. The reinforcing non-wovens consist of polyester fibers or the more temperature resistant aromatic polyamide fibers. The non-woven reinforced silicone modified epoxy coated tape backing of the present invention has improved thermal, chemical, water, and electrical insulation resistance, and improved lubricity over the prior art backings. Additionally, an important advantage of the silicone modified composition of the present invention is that it is possible to eliminate release coating the backing when used as a tape backing, as the silicone increases the lubricity of the backing; i.e. the adhesion of the adhesive mass is lowered to the extent that no release coating or release liner is required during use.
