Hi all.
I am working in a company that designs carbon steel products out of plate, bar and pipe material. We do not have manufacturing facility and neither we nor our fabricators have painting facility. As we obviously need to protect our products, and do not have where to paint them, we are using paint that does not require any special surface prep and paint in house. We leave pipe coated with anti-corrosive protection layer (blue or black, depending on the mill) and grind/sand off any rust accumulated on the rest of the material and weld areas. Basically prep the surface to SSPC-SP2/3 and apply the paint. For years we have been using Benjamin Moore Z24 Alkyd-Enamel (semi-gloss) brushed on. This is our standard paint procedure for service up to 350 °F. If we have a design for higher temps, we get these out to painting vendors for proper paint.
IS there anyone that can recommend any other paint that can be used for the above mentioned temperature and surface prep? Current paint is easy to use, but the finished product is something that i am not satisfied with. The surface becomes dirty rather easily and it just doesn't look too nice. I understand that without proper surface prep it is almost impossible to achieve good finish. I am just hoping that someone here can recommend something that is an improvement to the existing paint selection. I would like to stay away from epoxy coatings as those harden rather easily, want to keep it as simple as it is (we do not have a dedicated painter. whoever is free paints the equipment and sometimes, they need to be pulled away from the painting job to do something else ). We also do not like to have glossy finish. Semi-gloss, eggshell would work (not sure if this matters though).
Thanks in advance
