1. 见ISO 2409-2007:
The method is not suitable for coatings of total thickness greater than 250 μm or for textured coatings.
NOTE 2 The method, when applied to coatings designed to give a rough patterned surface, will give results which will show too much variation (see also ISO 16276-2).
2. 见ISO 16276-2-2007
The cross-cut test is suitable for film thicknesses up to 250 μm. The X-cut test is not limited by thickness.
For hard coatings, it might not be possible to use the cross-cut test, in which case the X-cut test should be
used.
For coatings containing pigments that have a flake format, the assessment of either the cross-cut or the X-cutmight be misleading. The coating manufacturer should be consulted for recommendations.作者: wang_7njcoating 时间: 2012-1-10 10:19

最好都用拉拔法,TB/T 1527-2011、JT 722-2008对涂料附着力要求都是5MPa以上,普遍采用拉拔法检测。作者: 阳光灿烂 时间: 2012-5-14 15:04
铁路标准1527,水性无机富锌划格法2级。
不过最好还是拉开法。作者: mengjie1019 时间: 2012-6-18 14:58
我的环氧富锌,划圈一级,至于划格,不好操作啊,劲小了漆膜毫无损伤,主要感觉还是跟膜厚有关吧。作者: zerozsh 时间: 2012-6-26 14:08
基本不推荐哦,道理我也不是太清楚哦作者: 阳光灿烂 时间: 2012-6-26 15:50
个人体会,拿锤子砸,漆膜不掉,说明附着力没问题/:victory作者: chenxujie 时间: 2012-7-4 08:14

防腐配套产品通常都是用拉拔测试附着的作者: zerozsh 时间: 2012-9-15 09:21
一般不建议这么做的,这种涂料一般做pull off好一点作者: shashou 时间: 2012-9-28 08:49 本帖最后由 shashou 于 2012-9-28 08:50 编辑
