Abstract

PURPOSE:To be able to use a self-cleaning coating compound for an electronic range without a heater, by adding to mix a pyrogenic agent which generates heat by irradiation of microwaves with a conventional self-cleaning coating compound. CONSTITUTION:A pyrogenic agent which generates heat by irradiation of microwaves such as silicon carbide, ferrite, or barium titanate, is added to be mixed with a self-cleaning coating compound to be coated on the inside panel of an oven 2. For example, a catalyst comprising 20 parts of manganese oxide and 4 parts of nickel oxide is blended with 20 parts of silicone resin binder. 20 parts of aluminum oxide, 8 parts of frit of phosphate group, and 21 parts of silica powder are blended as an assistant agent. Further 4 parts of organic bentonite is uniformly mixed with the above-mentioned compound as an additive. 2 parts of toluene, 1 part of xylene, and 8 parts of turpentine are mixed with it as a solvent to make a liquid compound. Then 60 parts of barium titanate is added to be mixed with it to make a paste coating compound.
