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
