ORGANIC LUBRICATING FILM AGENT COMPOSITION FOR PLASTICITY PROCESSING AND METALLIC THIN PLATE COATED THEREWITH

摘要

PURPOSE:To provide the title composition capable of enhancing the plasticity processing moldability of metallic thin plates, also improved in its cleaning removability from said thin plates, comprising, as the essential component, an esterified product or its salt of a copolymer with maleic anhydride and styrene as the main monomer constituents. CONSTITUTION:The objective composition containing, as the essential component, =10wt.% of an esterified product (or its salt) obtained by at least partially esterification of (A) a copolymer with maleic anhydride and styrene as the main monomer constituents at the molar ratio (1:99)-(75:25) with (B) at least one kind of hydroxyl group-contg. compound having 10-30C alkyl group or alkenyl group.
