Zusammenfassung: | PURPOSE: To obtain a high-frequency choke coil by covering it with a compsn. which can be set by heat and UV radiation. CONSTITUTION: A high-frequency chock coil is covered with a compsn. which can be set by heat and UV radiation and is such as to contain a resin mixture, composed of an epoxy resin (meta)crylate, polyether (meta)crylate, polyurethane (meta)crylate, metacrylic ester of polyfunctional alcohol, bisphenol A and decomposition product of and ethylenoxide and/or propyleneoxide. A light initiator is to be composed of benzoyl, acetophenone, phosphine benzoyl oxide, thio- initiator and benzophenone and thioxane coupled with a reaction accelerator, and a peroxide is to be composed of t-butyl permalenoate, 1,1-bis(t- butylperoxy)-3,3,5-trimethylcyclohexane, t-butylperoxy benzoic acid, or 2,2-bis-(t- butylperoxy)-butane. |
