Abstract

Abstract This invention provides articles and methods for surface protection which comprises a layer of a gel material having a cone penetration of about 100 to about 350 (10 -1 mm) and an ultimate elongation of at least 100% and a covering layer of a flexible material which is flexible when installed on the surface to be protected and is hardenable or curable so that after installation the covering layer hardens to hold the gel layer in position and protect the gel layer from mechanical and other environmental conditions. This invention is particularly suitable for providing surface protection for underwater structures by applying the gel layer to displace the water from the surface which is underwater and providing a water curable covering layer which, after being applied to the surface, cures underwater to provide the required mechanical protection for the gel layer.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 125 words
An article for protecting a substrate comprising: a layer of gel material for contacting the surface of a substrate comprising a gel being cured prior to contacting the substrate and having a cone penetration of about 100 to about 350 (10-lmm) and an ultimate elongation of at least about 100%; and a covering layer of flexible material adapted to carry said layer of gel material and enable placement of the gel material on a substrate and adapted to protect said gel material after.the gel is in place on the substrate comprising a material which is flexible during installation on the substrate and hardenable after placed on the substrate to thereby provide mechanical protection for the gel material positioned between the covering layer and the substrate.
Claim 2
Dependent Claim 125 words
An article for protecting a substrate comprising: a layer of gel material for contacting the surface of a substrate comprising a gel being cured prior to contacting the substrate and having a cone penetration of about 100 to about 350 (10-lmm) and an ultimate elongation of at least about 100%; and a covering layer of flexible material adapted to carry said layer of gel material and enable placement of the gel material on a substrate and adapted to protect said gel material after.the gel is in place on the substrate comprising a material which is flexible during installation on the substrate and hardenable after placed on the substrate to thereby provide mechanical protection for the gel material positioned between the covering layer and the substrate.
Claim 3
Dependent Claim 17 words
An article according to claim 1 wherein the covering layer is a fabric impregnated with a resin.
Claim 4
Dependent Claim 16 words
An article according to claim 2 wherein the resin in the covering layer is water curable.
Claim 5
Dependent Claim 93 words
An assembly comprising: a substrate; a layer of gel material in contact with the surface of the substrate comprising a material having a cone penetration of about 100 to about 350 (10- l mm) and an ultimate elongation of at least about 100%; and a layer of protective material over the layer of gel material which is flexible at the time of installation on the substrate and hardens after installation on the substrate to provide mechanical protection for the layer of gel material positioned between the substrate and the layer of protective material.
Claim 6
Dependent Claim 93 words
An assembly comprising: a substrate; a layer of gel material in contact with the surface of the substrate comprising a material having a cone penetration of about 100 to about 350 (10- l mm) and an ultimate elongation of at least about 100%; and a layer of protective material over the layer of gel material which is flexible at the time of installation on the substrate and hardens after installation on the substrate to provide mechanical protection for the layer of gel material positioned between the substrate and the layer of protective material.
Claim 7
Dependent Claim 17 words
An assembly according to claim 4 wherein the covering layer is a fabric impregnated with a resin.
Claim 8
Dependent Claim 18 words
6 . An assembly according to claim 5 wherein the resin in the covering layer is water curable.
Claim 9
Independent Claim 86 words
A method of protecting a substrate comprising: placing in contact with the surface of a substrate a gel material having a cone penetration of about 100 to about 350 (10 -1 mm) and being cured prior to being place in contact with the surface of the substrate; and placing over the gel material a covering material which is flexible at the time of installation thereon and cures or hardens after installation thereby providing mechanical protection for the gel material positioned between'the substrate and the covering material.
Claim 10
Independent Claim 86 words
A method of protecting a substrate comprising: placing in contact with the surface of a substrate a gel material having a cone penetration of about 100 to about 350 (10 -1 mm) and being cured prior to being place in contact with the surface of the substrate; and placing over the gel material a covering material which is flexible at the time of installation thereon and cures or hardens after installation thereby providing mechanical protection for the gel material positioned between'the substrate and the covering material.
Claim 11
Dependent Claim 17 words
A method according to claim 7 wherein the covering layer is a fabric impregnated with a resin.
Claim 12
Dependent Claim 16 words
A method according to claim 8 wherein the resin in the covering layer is water curable.
Claim 13
Dependent Claim 105 words
A kit-of-parts comprising: a sheet or tape of gel material for contacting the surface of a substrate comprising a gel being cured prior to contacting the substrate and having a cone penetration of about 100 to about 350 (10- l mm) and an ultimate elongation of at least about 100%; and a sheet or tape of protective material for covering the gel material after the gel is in place on the substrate comprising a material which is flexible during installation on the substrate and hardenable after placed on the substrate thereby providing mechanical protection for the gel material positioned the protective material and the substrate.
Claim 14
Dependent Claim 105 words
A kit-of-parts comprising: a sheet or tape of gel material for contacting the surface of a substrate comprising a gel being cured prior to contacting the substrate and having a cone penetration of about 100 to about 350 (10- l mm) and an ultimate elongation of at least about 100%; and a sheet or tape of protective material for covering the gel material after the gel is in place on the substrate comprising a material which is flexible during installation on the substrate and hardenable after placed on the substrate thereby providing mechanical protection for the gel material positioned the protective material and the substrate.
