Abstract
Abstract Environmental sealing may be achieved by extruding a sealing material having a cone penetration value preferably from 100-350 (10-1 mm) and an ultimate elongation of at least 100% from a material-dispensing gun, having means for example a mesh, for causing the material to be mechanically deformed preferably by shear and preferably causing it to be comminuted.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
118 words
A method of environmentally protecting a substrate which comprises: (a) subjecting a sealing material that is at least partially cross-linked and having an ultimate elongation according to ASTM D638-80 of at least 100% and a cone penetration at cure according to ASTM D217-68 at 21° C. of greater than 100 (10-1 mm) to a shear force greater than its ultimate cohesive strength to cause a fragmentation of the sealing material prior to but in the process of contacting a substrate to be protected; (b) causing the sheared material to flow over and contact a surface of the substrate to be protected; and (c) maintaining the sheared material in contact against the surface of the substrate to be protected.
Claim 2
Independent Claim
118 words
A method of environmentally protecting a substrate which comprises: (a) subjecting a sealing material that is at least partially cross-linked and having an ultimate elongation according to ASTM D638-80 of at least 100% and a cone penetration at cure according to ASTM D217-68 at 21° C. of greater than 100 (10-1 mm) to a shear force greater than its ultimate cohesive strength to cause a fragmentation of the sealing material prior to but in the process of contacting a substrate to be protected; (b) causing the sheared material to flow over and contact a surface of the substrate to be protected; and (c) maintaining the sheared material in contact against the surface of the substrate to be protected.
