The granulated powder adhesion improver which consists of the hydrate of the sodium acetate which features

摘要

PROBLEM TO BE SOLVED: To provide a method for strongly adhering a layer comprising a fluorine-containing polymer (hereafter referred to the polymer layer) without applying a special surface treatment on the polymer layer to a layer comprising an elastomer (hereafter referred to the elastomer layer) by vulcanization adhesion, wherein a cost of hose products is improved due to the elimination of the surface treatment that complicates processes for manufacturing a hose and increases a manufacturing cost, when manufacturing a laminated material composed of the polymer layer and the elastomer layer.;SOLUTION: In the method, a vulcanization adhesion improver consisting of a hydrate of sodium acetate is used when adhering the polymer layer to the elastomer layer.;COPYRIGHT: (C)2003,JPO
