Hello,
I'm trying to apply an epoxy coating resin (bisphenol A epoxy resin) onto mild steel, with a bar coat of 100 micra. The resin to hardener ratio is 2:1.
When the surface begin drying some defects appear as the photo show. The surface preparation was done according to  ASTM- G1- 03, and I tried to repeat the process with a bar coat of 200 micra and the result was the same. 
What is wrong? 
Can you help me?
Many thanks

Thank you for your suggestions.

In fact, we are using this resin for anticorrosive tests. According to TDS this resin is suitable for this type of tests, should we try another one?

We are looking for a resin model without any additive to be used as anticorrosive primer. Do you have any other suggestion?




Thank you in advance.
