<P>PROBLEM TO BE SOLVED: To provide a method for further improving acid resistance of a perfluoropolyether gel cured product excellent in heat resistance, solvent resistance, chemical resistance, weatherability, mold releasability, water repellency, oil repellency, etc., without impairing these characteristics of the perfluoropolyether gel cured product. <P>SOLUTION: A perfluoropolyether gel composition is used, in which the blending amount of a non-functional linear perfluoro compound (E) acting as a plasticizer is controlled within a specified range of 5 pts.mass or more and less than 20 pts.mass to 100 pts.mass total of a mixture of a linear perfluoropolyether compound (A) containing two or more alkenyl groups and a linear perfluoropolyether compound (B) having one alkenyl group in a molecule, which is a main agent (base polymer) of the composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
