Abstract
Abstract In the joining of silicone-coated fabrics in the present invention, a silicone rubber adhesive, which is plastic at room temperature and is an addition-curing type containing platinum-type catalyst or a radical-curing type containing organoperoxide, is inserted into the overlap region of said silicone rubber-coated fabrics. This overlap region is then hot-cured after press-adhering or is hot-cured while press-adhering. As a consequence, the silicone-coated fabrics are tightly bonded in an accurate, watertight and airtight manner.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
58 words
Method for joining silicon rubber-coated fabrics, characterized by overlapping silicone rubber-coated fabrics with the insertion at the overlap region of a silicone rubber adhesive which is plastic at room temperature and which is a radical-curing type containing organoperoxide, or an addition-curing type containing a platinum-type catalyst, followed by press-adhering and then by hot-curing, or by hot-curing during press-adhesion.
Claim 2
Dependent Claim
58 words
Method for joining silicon rubber-coated fabrics, characterized by overlapping silicone rubber-coated fabrics with the insertion at the overlap region of a silicone rubber adhesive which is plastic at room temperature and which is a radical-curing type containing organoperoxide, or an addition-curing type containing a platinum-type catalyst, followed by press-adhering and then by hot-curing, or by hot-curing during press-adhesion.
Claim 3
Dependent Claim
19 words
