Primer increases the adhesion of the topcoat or paint to the material. Types of Primer:

• Waterborne primer

• Epoxy Primer

• Wash Primers

• Fluid Resistant Primer

The topcoat is the final coating on a component. Types of finish coatings are:

• Aliphatic Polyurethane Coatings

• Commercial Coatings

• Epoxy Topcoats

• Fluid Resistant Topcoats

• Fuel Tank Coating is a specific coating applied to the components on the interior of a fuel tank or fuel wetted areas of an aircraft. They are specifically designed to prevent corrosion in these harsh environments.

• Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives. The lubricant is applied to a substrate by spray, dip, or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases wear life of the substrate.

• Sol-Gel is a nonhazardous coating that is be applied to titanium using a variety of methods (dip, immersion, brushing, spraying).
