摘要:
The primer contains at least one compound selected from organosilanes R 1 -(CH 2 ) a -(O-(CH 2 ) c ) b -Si-[(O-(CH 2 ) c ) b -OR 2 ] 3 wherein a=0-4, b=0-1, c=1-4, R 1 is -CH 3 , -NH 3 , -CH=CH 2 , -CH-CH 2 -O l and R 2 is -CH 3 or -C 2 H 5 , and/or epoxy adducts of phosphoric acid. It dispenses with the use of acid and/or toxic pretreatment solutions, and allows two-coat systems to be applied in one pass on standard coil coating lines.
