PRODUCTION OF MODIFIED POLYESTER RESIN COMPOSITION, COATING, PRECOATED STEEL PLATE AND MODIFIED POLYESTER RESIN

摘要

PURPOSE: To provide a modified polyester resin composition capable of giving coating films with high processability without impairing coating film hardness and contamination resistance. ;CONSTITUTION: This modified polyester resin composition has such structure that a lactone is ring opening addition-polymerized to the side chain of a linear polyester resin. This composition can give coating films satisfying balance between hardness and processability both in high levels.;COPYRIGHT: (C)1994,JPO&Japio
