Method of coating fixed resistors with a one-component epoxy resin coating material and fixed resistors coated with said one-component epoxy resin coating material

摘要

One-component epoxy resin coating materials comprising (A) an epoxy resin or a mixture of epoxy resins, (B) as hardener for the epoxy resin at least one aromatic dicarboxylic acid dihydrazide or a triazine compound of the formula I <IMAGE> (I) (R=alkylamino or dialkylamino having 1 or 2 carbon atoms in the alkyl moieties, phenylamino or hydrazino) and (C) an anti-sagging agent or an inorganic filler or a mixture of anti-sagging agent and an inorganic filler, are used for the coating of fixed resistors. The resultant coatings exhibit good heat, moisture and cracking resistance.
