Abstract
Electrical joint compounds for the protection of electrical connections are formed from a solution of polymer dissolved in solvent with or without conductive filler. Partially cured thermosetting polymers are preferred as they flow under service conditions to better seal the electrical joints. Thermosetting polymers which cure by an addition mechanism are preferred over those which cure by condensation, and polyimides are most preferred.
Claims22
In a method of making an electrical connection wherein joint compound is applied, the improvement comprising applying as joint compound a solution of polymer and electrically conductive filler dissolved in solvent.
In a method of making an electrical connection wherein joint compound is applied, the improvement comprising applying as joint compound a solution of incompletely cross linked flowable thermosetting polymer dissolved in solvent, and not fully cross linking the polymer until the electrical connection is placed in use.
