ASTM D4752采用溶剂擦试法测量硅酸乙酯 (无机) 富锌底漆耐MEK的标准实践规程
标准名称
ASTM D4752 Standard Practice for Measuring MEK Resistance of Ethyl Silicate (Inorganic) Zinc-Rich Primers by Solvent Rub
ASTM D4752采用溶剂擦试法测量硅酸乙酯 (无机) 富锌底漆耐MEK的标准实践规程
适用范围
Scope:
This practice describes a solvent rub technique for assessing the MEK resistance of ethyl silicate (inorganic) zinc-rich primers. The MEK resistance of some two-component ethyl silicate zinc-rich primers has been shown to correlate well with the cure of the primer as determined by diffuse reflectance infrared spectroscopy. 2 The technique can be used in the laboratory, field, or in the fabricating shop. Practice D5402 is the preferred method for organic coatings.
