Abstract
Abstract A method for sealing the interstices between individual cables of a cable bundle to achieve the sealing of the cable bundle in the longitudinal direction applying a liquid resin system to the area between the cables, the system comprising the reaction of a polyisocyanate and at least one fatty acid polyol having a hydroxy number of at least about 150 and an acid number of no greater than about 1.0, followed by curing thereof to a non-flowable state.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A method for sealing the interstices between individual cables of a cable bundle to achieve a sealing of said cable bundle in the longitudinal direction thereof, comprising applying a curable liquid resin system to the area between said cables, said resin system comprising the reaction product of a polyisocyanate and at least one fatty acid polyol having a hydroxyl number of at least about 150 and an acid number of no greater than about 1.0, followed by curing thereof to a non-flowable state.
Claim 2
Independent Claim
83 words
A method for sealing the interstices between individual cables of a cable bundle to achieve a sealing of said cable bundle in the longitudinal direction thereof, comprising applying a curable liquid resin system to the area between said cables, said resin system comprising the reaction product of a polyisocyanate and at least one fatty acid polyol having a hydroxyl number of at least about 150 and an acid number of no greater than about 1.0, followed by curing thereof to a non-flowable state.
Claim 3
Dependent Claim
22 words
The method of claim 1, wherein said fatty acid polyol has a hydroxyl number of 190 and an acid number below 1.
Claim 4
Dependent Claim
12 words
The method of claim 1, wherein said fatty acid polyol is unsaponifiable.
Claim 5
Dependent Claim
15 words
The method of claim 1, wherein said fatty acid polyol predominantly contains primary hydroxyl groups.
Claim 6
Dependent Claim
19 words
The method of claim 1, wherein said liquid resin system further contains an effective amount of a crosslinking agent.
Claim 7
Dependent Claim
19 words
The method of claim 1, wherein said liquid resin system further contains an effective amount of a surface-active agent.
Claim 8
Dependent Claim
19 words
The method of claim 1, wherein said liquid resin system further contains an effective amount of a water-absorbent material.
