Rehardening of EC-2273 Potting Compound in F-4 Aircraft Electrical Components.
Abstract
The useful lifetimes for electrical connectors potted with EC-2273 can be doubled by skin-hardening the surface of the potting compound with a 25% solution of hexamethylene diisocyanate in hexane or with a mixture of hexamethylene diisocyanate, butylisocyanate and hexane. These treatments are applicable to partially deteriorated as well as to the nondeteriorated potting compound. The treatments are carried out simply by immersion of the electrical component in the hardening solution for a period of three days. (Author-PL)
