Title: Primer composition for corrosion prevention and prevention of corrosion using same
Inventor: MORITA TORU
IPC: C08L33/04
Filed: 1990-02-02
Abstract: PURPOSE:To provide a primer composition which can give a layer of excellent corrosion prevention to the surface of a metallic pipe by mixing an acryl rubber with a calcium compound and an organic solvent as essential components. CONSTITUTION:An acryl rubber or its mixture with another polar rubber (e.g. chlorinated butyl rubber) is mixed with a calcium compound (e.g. calcium hydroxide), an organic solvent (e.g. toluene) and necessary additives such as a tackifier, an antioxidant, a filler, a colorant and a vulcanization accelerator to produce a primer composition for corrosion prevention. A primer layer formed by applying the primer composition to the surface of a metallic pipe exhibits an excellent alkali resistance owing to the effect of the calcium compound. Cathodic peeling caused by the intrusion of an environmental aqueous solution from the damaged part of the corrosion-preventive base formed on the primer layer can be decreased, and therefore excellent corrosion prevention is possible.

Abstract: PURPOSE:To raise the etching rate in the depth direction and to enable the anisotropical etching process to be performed by a method wherein a part irradiating infrared rays and an etching vessel are provided to wet-etch a semiconductor substrate being irradiated with the infrared rays. CONSTITUTION:A part 1 irradiating infrared rays 2 and an etching vessel 6 are provided to wet-etch a semiconductor substrate 5 being irradiated with the infrared rays 2 in the vessel 6. For example, the infrared rays 2 in the wavelength absorbing the characteristics of an oxide film to be etched are emitted by the infrared ray emitting device 1 and then the etching vessel 6 is filled up with fluoric acid solution 20. Then, an oxide film 4 is formed on the silicon substrate 5 and when the oxide film 4 is etched away using resist 3 covering the parts not to be etched as mask, the molecular oscillation on the parts of oxide film 4 not covered with the resist mask 3 is intensified to raise temperature in the parts since the parts are exposed to the infrared rays. Through these procedures, the etching rate of the oxide film 4 by the fluoric acid solution 20 depending upon the temperature of the oxide film 4 is raised corresponding to the raise in temperature in the oxide film 4 so that the anisotropical etching process may be performed.
