Abstract
Abstract An article that may be employed to protect a substrate by wrapping the article around the substrate. The article comprises a flexible matrix which is composed of a first material and comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch 3 ; and an impregnant which is composed of a second material which has a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%, and comprises a plurality of interconnected segments which lie within the interstices of the matrix. The matrix and the impregnant are such that, when the article is stretched, the matrix reaches its ultimate elongation before the impregnant reaches its ultimate elongation.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
151 words
An article for protecting a substrate from moisture, comprising: (1) a flexible, extensible matrix which (a) is composed of a first material and (b) comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch 3 , and (2) a moisture-insensitive impregnant which (a) is composed of a second material which when cured has a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%, and (b) comprises a plurality of interconnected segments which lie within the interstices of the matrix, the impregnant being cured prior to coming into contact with any part of the substrate to be protected; the matrix and the impregnant being such that, when the article is stretched, the matrix reaches its ultimate elongation before the impregnant reaches its ultimate elongation so as to provide a continuous moisture protection coating over the substrate.
Claim 2
Dependent Claim
151 words
An article for protecting a substrate from moisture, comprising: (1) a flexible, extensible matrix which (a) is composed of a first material and (b) comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch 3 , and (2) a moisture-insensitive impregnant which (a) is composed of a second material which when cured has a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%, and (b) comprises a plurality of interconnected segments which lie within the interstices of the matrix, the impregnant being cured prior to coming into contact with any part of the substrate to be protected; the matrix and the impregnant being such that, when the article is stretched, the matrix reaches its ultimate elongation before the impregnant reaches its ultimate elongation so as to provide a continuous moisture protection coating over the substrate.
