Abstract
Abstract A coated fabric having a cured, synthetic elastomeric compound bonded thereto in a fashion to control the final weight and other physical and chemical properties thereof. The method comprehends the exposure of a fabric to an elastomer during its pot life to allow it to penetrate the fabric under "blotting" conditions and then quickly curing the elastomeric compound.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A coated fabric comprising a cured layer of a preselected synthetic heat activated elastomeric compound including a urethane prepolymer bonded to and impregnating the fabric on only one side without saturating the fabric with the compound, the elastomeric compound prior to association with the fabric having been characterized by a semi-solid viscosity at approximately ambient temperature and very short pot life on the order of three minutes and the fabric having been deposited on a layer of the elastomeric compound without exerting any mechanical pressure on the fabric resulting in the association of a layer of elastomeric compound of substantially uniform depth with said one side of the fabric and the elastomeric layer having been cured to provide a bonded coating of uniform thickness throughout and a fabric having a desired weight which is a flexible, abrasion, resistant, leak-proof fabric having excellent fuel, fuel additive, oil, solvent and ozone resistant properties.
Claim 2
Dependent Claim
151 words
A coated fabric comprising a cured layer of a preselected synthetic heat activated elastomeric compound including a urethane prepolymer bonded to and impregnating the fabric on only one side without saturating the fabric with the compound, the elastomeric compound prior to association with the fabric having been characterized by a semi-solid viscosity at approximately ambient temperature and very short pot life on the order of three minutes and the fabric having been deposited on a layer of the elastomeric compound without exerting any mechanical pressure on the fabric resulting in the association of a layer of elastomeric compound of substantially uniform depth with said one side of the fabric and the elastomeric layer having been cured to provide a bonded coating of uniform thickness throughout and a fabric having a desired weight which is a flexible, abrasion, resistant, leak-proof fabric having excellent fuel, fuel additive, oil, solvent and ozone resistant properties.
Claim 3
Dependent Claim
19 words
A coated fabric as defined in claim 1 wherein the fabric is a synthetic fabric having a preselected weight.
Claim 4
Dependent Claim
15 words
A coated fabric as defined in claim 2 wherein the synthetic fiber is a nylon.
Claim 5
Dependent Claim
16 words
A coated fabric as defined in claim 2 wherein the synthetic fabric is an aramid fiber.
Claim 6
Dependent Claim
15 words
A coated fabric as defined in claim 2 wherein the synthetic fabric is a rayon.
Claim 7
Dependent Claim
20 words
A coated fabric as defined in claim 1 wherein the fabric is a natural fiber fabric having a preselected weight.
Claim 8
Dependent Claim
13 words
A coated fabric as defined in claim 6 wherein the fabric is cotton.
Claim 9
Dependent Claim
58 words
A coated fabric as defined in claim 1 wherein the coated fabric is produced by the exposure of the fabric substrate to the elastomer to allow it to penetrate the fabric under blotting conditions whereby the penetration of the compound into the fabric is governed by the weight of the fabric on the compound and the viscosity thereof.
