APPARATUS AND METHOD FOR COATING

摘要

PURPOSE:To provide a coating apparatus wherein warpage of a member due to change in temp. is prevented from being generated when an org. solvent is applied and a narrow bead clearance can be highly accurately kept. CONSTITUTION:In a coating apparatus for applying an org. solvent coating liq. on a substrate by means of a slide bead coater, the slide bead coater is constituted of a raw material with a linear expansion coefficient of at least 3X10<-6>. The slide bead coater is constituted of an alloy consisting of 9.0-10.5% Cr, 52.5-56.0% Co and the remaining part consisting of Fe and inevitable impurities.
