Fast-Setting Low-Viscous Epoxy Compositions for Impregnation and Adhesion of Electrotechnical Products

Improvement of electrical insulating and adhesion characteristics of epoxydian resins cured with aminoimidazoline curing agents is considered. It is determined that necessary characteristics of fabricability (low viscosity and time of curing) and adhesion and cohesion strength to various metal substrates (steel, latten brass, coper, and aluminum) require low-viscous aminoimidazoline curing agents along with epoxy active diluents. The reasonability and effectiveness of combined action of the solutions of the products of condensation represented by Mannich bases containing imidazoline rings and initial aminoimidazolines as curing agents is demonstrated.
