1.I do have 2 question to the FBE application. I would like to know if the chemical pre-treatment, can be eliminated from the process. Just found in a specification a condition: if the applicator can prove that FBE will meet the adhesion tests, without chemical pre-treatment, the procedure can be approved. Is the pre-hemical treatement a must?
2. If the chemical pre-treatment should be done, then is it still neccessary a surface preparation (degreasing) according to SSPC SP 1??
Thanks in advance for your help!
