laughing哥:查了该产品的说明书,里面是没有说明具体的含锌量。另外,既然称作双组份富锌环氧漆,那么含锌量起码大于80%了。 (2015-07-27 15:52)

chgzh0101:这个可不一定,环氧富锌底漆和无机富锌底漆中锌粉含量通常分为三个等级,Level 1: equal to or greater than 85%; Level 2: equal to or greater than 77% and less than 85%; Level 3: equal to or greater than 65% and less than 77%. (2015-07-29 11:41)
