PRE-COATED STEEL SHEET WHICH IS EXCELLENT IN THERMOSTABLE FOOD CONTAMINATION PREVENTION AND WORKABILITY

摘要

PURPOSE: To provide a pre-coated steel sheet which is excellent in thermostable food contamination prevention and workability and a wall material for a microwave oven made of the pre-coated steel sheet. ;CONSTITUTION: A pre-coated steel sheet has a base coating film containing epoxy modified polyester resin, and a final coating film which contains polyvinylidenefluoride resin and acrylic resin by a wt. ratio of 70/30-40/60 in polyvonylidenefluoride resin/acrylic resin and is 20% in crystallinity on a surface of the steel sheet to which chemical and synthetic treatment is applied, which is excellent in thermostable food contamination prevention and workability. Then, a wall material for a microwave oven is composed of the pre-coated steel sheet.;COPYRIGHT: (C)1996,JPO
