Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
A method of environmentally protecting a substate which comprises: (a) subjecting a sealing material having an ultimate elongation according to ASTM D638080 of at least 100% and a cone penetration according to ASTM D217-68 at 21° C. of greater than 100 (10-1 mm) in the presence ofa solvent or suspending medium to mechanical deformation sufficient to cause the material to be fragmented prior to but in the process of being applied to a substrate to be protected; (b) causing the fragmented material to flow and envelop a surface of the substrate to be protected: and thereafter (c) maintaining the fragmented material in contact against the surfaceo fhte substrate to be protected.
Claim 2
Independent Claim
111 words
A method of environmentally protecting a substate which comprises: (a) subjecting a sealing material having an ultimate elongation according to ASTM D638080 of at least 100% and a cone penetration according to ASTM D217-68 at 21° C. of greater than 100 (10-1 mm) in the presence ofa solvent or suspending medium to mechanical deformation sufficient to cause the material to be fragmented prior to but in the process of being applied to a substrate to be protected; (b) causing the fragmented material to flow and envelop a surface of the substrate to be protected: and thereafter (c) maintaining the fragmented material in contact against the surfaceo fhte substrate to be protected.
Claim 3
Dependent Claim
33 words
A method according to claim 1, in which: (a) the material is subjected to shear, (b) a container is provided around the substrate; and (c) then the material is placed into the container.
Claim 4
Dependent Claim
38 words
A method according to claim 1, in which: (a) the material is subjected to shear; (b) then the material is placed into a container; and (c) then the container with the material therein is positioned around the substrate.
Claim 5
Dependent Claim
21 words
A method according to claim 1, in which the material has a cone penetration value of at least 150 (10-1 mm).
Claim 6
Dependent Claim
37 words
