Title:

CURABLE PERFLUOROPOLYETHER COMPOSITION, RUBBER GIVEN BY USING CURED PRODUCT OF THE SAME, AND GEL PRODUCT

Document Type and Number:

Japanese Patent JP2006249416

Kind Code:

A

Abstract:

To provide a curable perfluoropolyether rubber composition capable of giving a cured product excellent in low permeability of an acidic gas and/or a sulfur-containing gas, to provide a curable perfluoropolyether gel composition, to provide a rubber containing the cured product, and to provide a gel product.

This curable perfluoropolyether composition contains (A) a straight chain perfluoropolyether compound which has at least two alkenyl groups in its molecule and further has a perfluoropolyether structure containing repeating units -CaF2aO- (a is an integer of 1 to 6) in its main chain, (B) an organosilicon compound which has at least two hydrogen atoms bonded to silicon atoms in it molecule, (C) an inorganic powder which chemically and/or physically adsorbs the acidic gas and/or the sulfur-containing gas, and (D) a hydrosilylation catalyst.
