Abstract
The invention provides a heat-resistant anti-static adhesive film having at least includes a top film, a silane-treated release layer on an underlying substrate layer, and a pressure-sensitive adhesive layer coated over the release layer. The pressure-sensitive adhesive layer is obtained by adding a plasticizer, an ionic compound or an anti-static agent, a cross-linking agent and aliphatic or alicyclic multi-functional isocyanate into (meth)acrylate polymer of the reactive silane compound. The composition has a long working life (pot life) of up to 24 hours and anti-static capability. A pressure-sensitive patch or surface protective film containing the abovementioned composition in the form of sheets or strips is capable of standing high temperature of 150 for up to 3 hours without leaving glue residue.
