<p>A composition designed for pumping into flooded electrical cables to displace water. It contains a liquid epoxy resin having a viscosity of about 1.2-250 poises (ASTM D445), and an epoxide equivalent of about 150-198 (ASTM A16552) and an amine type hardener. An oxidized vegetable oil is incorporated to maintain substantially permanent flexibility in the composition after curing. A phthalate or phosphate ester provides reduced initial viscosity to permit pumping of the composition into the cables. A cyclic alcohol such as cyclohexanol provides a non-separating condition and particularly prevents bleed-out of the plasticizer.</p> |
