ADHESIVE COMPOSITION FOR PLASTIC FILM-LAMINATED STEEL SHEET

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition for plastic film-laminated steel sheets that has blocking resistance during lamination, enables the completion of heat-curing by the residual heat during lamination and requires no heating and aging treatment after lamination.;SOLUTION: The adhesive composition for plastic film-laminated steel sheets includes (A) a saturated polyester resin having a number-average molecular weight of 5,000-30,000 and a Tg of 5-50°C, (B) a saturated polyester resin having a number-average molecular weight of 5,000-30,000 and a Tg of 51-100°C, (C) a highly etherified amino resin, (D) an epoxy resin having a number-average molecular weight of 500-5,000 and (E) a strong acidic compound. The adhesive composition contains the component (A) in an amount of 40-70 pts.mass, the component (B) in an amount of 10-40 pts.mass, the component (C) in an amount of 1-10 pts.mass, the component (D) in an amount of 5-20 pts.mass and the component (E) in an amount of 0.01-10 pts.mass when the total of the components (A)-(E) is 100 pts.mass.;COPYRIGHT: (C)2010,JPO&INPIT
