Abstract
Abstract This invention provides a sealing material which comprises a layer of elastomeric sealant having a cone penetration from about 100 to 350 (10 -1 mm) and an ultimate elongation of at least 50% and disposed on a surface thereof an air drying or air curing material which sufficiently adheres to the surface of the elastomeric sealant to permit placement of the elastomeric sealant on a substrate and which reduces the surface tack of the elastomeric sealant.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
110 words
A sealing material comprising in combination: a. an elastomeric sealant comprising a polysiloxane, a polyurethane, a polybutyl or a triblock copolymer and having a cone penetration from about 100-350 (10 -1 mm) and an ultimate elongation of at least 50%; and b. a backing material disposed on a surface of the elastomeric sealant comprising an air drying or air curing material which is liquid, dissolved in a solvent or dispersed in a carrier and which, when dried or cured, sufficiently adheres to the surface of the elastomeric sealant and provides means for installation of the elastomeric sealant on a substrate and which reduces the surface tack of the elastomeric sealant.
Claim 2
Dependent Claim
110 words
A sealing material comprising in combination: a. an elastomeric sealant comprising a polysiloxane, a polyurethane, a polybutyl or a triblock copolymer and having a cone penetration from about 100-350 (10 -1 mm) and an ultimate elongation of at least 50%; and b. a backing material disposed on a surface of the elastomeric sealant comprising an air drying or air curing material which is liquid, dissolved in a solvent or dispersed in a carrier and which, when dried or cured, sufficiently adheres to the surface of the elastomeric sealant and provides means for installation of the elastomeric sealant on a substrate and which reduces the surface tack of the elastomeric sealant.
