Title:
SILICONE MOISTURE-BLOCKING MATERIAL FOR CABLE AND ITS APPLICATION
Document Type and Number:
Japanese Patent JPS63298913
Kind Code:
A
Abstract:
There is provided a method of extending the serviceable life of a stranded conductor electrical distribution cable wherein the interstices of the conductor are filled with a curable silicone water block composition which is subsequently cured to a non-flowing state. The composition has a low viscosity and comprises (A) an Si-H endblocked polydiorganosiloxane fluid, (B) a polydiorganosiloxane fluid endblocked with an unsaturated organic radical, (C) a siloxane crosslinker, (D) a hydrosilation catalyst and (E) a polymerization inhibitor. Proper selection of catalyst and inhibitor concentrations imparts a controllable viscosity-time profile to the composition and allows cables of various sizes and lengths to be filled before the water block composition cures.
