Fine-grain zinc offers moderate bare corrosion protection for steel and other metals prior to painting. This excellent pretreatment conversion coating method works on ferrous metals and zinc/zinc alloy coated metals before paint is applied, meeting U.S. federal specifications and military standards.
This pretreatment for steel is a frequent requirement for military applications. Heavy-grain zinc coating often has a thicker and coarser consistency that creates more corrosion resistance by placing more sacrificial zinc on the surface.
Manganese is used for its wear resistance and initial break-in properties. The heavy grain of the manganese has excellent oil retention that acts as a lube on moving parts and initial break-in and corrosion resistance. It can also be used as a base for military CARC painting.
Iron phosphate acts as the base for painting or powder coating, providing greater adhesion for the paint/powder coat as well as excellent corrosion protection.
Black oxide is a conversion coating that reacts with the surface creating a black color that provides improved cosmetics compared to the original steel as well as some corrosion protection. The addition of a post treatment of oil will increase the corrosion protection, create a deeper color and can minimize abrasion during break in of mating parts.
Chem film, sometimes referred to as chemical conversion coating, chromate coating, or yellow chromate, is a chemical conversion coating used on aluminum parts to improve corrosion protection or to be used as a base for painting.
Ultrasonic cleaning is a cleaning method using high frequency sound waves in a solution. Ultrasonic cleaning is powerful enough to remove tough contaminants, yet gentle enough not to damage the substrate. It provides excellent penetration and cleaning in the smallest crevices and between tightly spaced parts in a cleaning tank.
Vapor degreasing is a solvent cleaning process in vapor form. The vapors can clean hard to reach areas and parts that are not able to be submerged in a fluid.
Pickle and Oil
Pickle and oil uses an acid solution and rinse stage to remove rust or scale from ferrous metals. This provides superior surface preparation for powder coating or painting.
