Primer and Topcoat Painting
OEM-compliant wet painting for aerospace and defense applications
Process Description
Primer and topcoat painting is an established coating process used for functional protection and surface finishing of components in the aerospace and defense industries. At Aero-Coating, painting is applied as a technically integrated part of defined coating systems. The objective is reproducible coating structures, clearly defined protective functions, and full specification compliance.
Primer and topcoat systems are multi-layer coating structures, typically consisting of a primer for adhesion promotion and corrosion protection support, and a topcoat for protection against environmental exposure, fluids, and mechanical stress. Application is performed as wet painting, either manually or automated, depending on component geometry, production volume, specification requirements, and surface quality requirements. Coating thicknesses, curing parameters, and process sequences are controlled, documented, and validated.
Typical applications include aerospace and defense structural components, individual parts and assemblies, visible surfaces with defined requirements, and functional surfaces with protective or identification purposes. Painting is frequently combined with upstream or downstream coating processes.

Does Aero-Coating paint exclusively with robots?
No. Application is performed as wet painting, either manually or automated, depending on component geometry, production volume, specification, and surface quality requirements. We selectively use painting robots and automated equipment for fasteners and RBC coatings.
Which coating systems are processed?
We process primer and topcoat systems in accordance with OEM and program requirements. Coating thicknesses, curing parameters, and process sequences are controlled, documented, and validated. The applicable specification is reviewed and implemented on a project-specific basis.
Does painting replace metallic corrosion protection processes?
No. Primer and topcoat painting is not a replacement for metallic corrosion protection coatings such as IVD Aluminum or vacuum cadmium. It is a functional component of an overall coating system whose effectiveness depends on correct design and process control.
