COMPOSITION FOR ADHERING PLACING POWDER OR SHEET FOR FIRING

摘要

PURPOSE:To facilitate a discrimination of the applied state of an adhesive on a carbon board as a setter and to maintain satisfactory adhesive property even after drying by blending an acrylate copolymer-based compsn. for bonding a sheet or placing powder for firing to the setter with a specified coating film regulating agent. CONSTITUTION:An acrylate copolymer-based compsn. for bonding a sheet or placing powder for preventing melt sticking to the surface of a carbon board on which a body to be fired is put and fired is blended with 1-25wt.% PVA, methylcellulose or carboxymethylcellulose as a coating film regulating agent for regulating viscosity, adhesive strength and compsn.
