PAD FOR PREVENTING AXIAL SLIP FOR USE IN GRINDING EYEGLASS LENS COATED WITH FLUORINE

摘要

A pad for preventing the axial slip for use in grinding an eyeglass lens coated with fluorine, characterized in that it comprises a laminate of a first pressure-sensitive adhesive layer, an elastic layer, an adhesive layer, a resin film and a second pressure-sensitive adhesive layer, wherein the elastic layer has a thickness of 0.2 to 3 mm, an elongation of 150 to 500 % and a tensile strength of 5 to 200 Kg/cm², the adhesive layer has an adhesion strength of 2 to 100 kg/25 mm, and the resin film has an elongation of 50 to 700 % and a tensile strength of 25 to 300 MPa. The above pad for preventing the axial slip is fully effective and allows the processing of a raw lens into a desired shape, even in the case of an eyeglass lens coated with fluorine.
