Phosphate coating process

WebThe phosphating process is pretty common for equipment parts that are made of steel because the iron in the steel is necessary for the coating to form. When resistance to wear and galling is required, manganese phosphate coating is the right coating to apply. There are different phosphate coatings available and manganese coating is the hardest. Webto epoxy coating. 6. After the part has been cleaned and zinc phosphated, it is immersed in liquid epoxy and coated to a smooth and uniform 0.7 - 0.9 mils.The benefits of E-Coat are that the process negates drips and sags and allows for reproducible results day after day. Furthermore, since coating is applied as a liquid, the epoxy travels into
