PPG Aerospace Deft 9N-060 BAC 4910 Green BMS 10-11AC Primer – Quart Kit for Aerospace Structural Surfaces

PPG Aerospace Deft 9N-060 is a green, two-component corrosion-inhibiting epoxy primer qualified to Boeing Material Specification BMS 10-11AC Type I, Class A, Grade E — one of the most widely specified aerospace primer qualifications in the commercial aviation industry. Used as a primer coat on aircraft structural aluminum, steel, and composite surfaces before topcoat application, 9N-060 provides outstanding corrosion inhibition through its chromate or chromate-free inhibitor system, combined with strong adhesion to the substrate and compatibility with Boeing-qualified aerospace topcoat systems.

BAC 4910 primers are critical to the long-term structural integrity of commercial aircraft — the primer coat prevents the corrosion of underlying metal structure that, if left unchecked, can cause structural degradation requiring costly repairs or component replacement. 9N-060’s green color is the standard identifier for corrosion-inhibiting primer in Boeing aircraft painting systems, providing easy visual confirmation of primer application on inspected surfaces.

The quart kit provides a practical maintenance quantity for line maintenance painting, repair zone priming, and small-area touch-up operations where a full gallon would exceed the material requirements of the job. Mix and apply per the PPG Deft 9N-060 product data sheet and applicable Boeing Surface Finish Specification for your specific aircraft type and repair category.

Technical Information

Deft 9N-060 BAC 4910 uses a two-component epoxy primer system comprising an epoxy resin base and an amine or polyamide hardener. The corrosion inhibitor system — historically chromate-based and now available in chromate-free alternatives — provides active corrosion protection by releasing inhibiting ions that passivate the metal substrate surface, preventing anodic oxidation reactions that initiate and propagate corrosion. The BMS 10-11AC qualification requires the primer to meet specific corrosion resistance, adhesion, and overcoating performance requirements defined by Boeing’s material engineering organization.

The two-component system must be mixed in the correct ratio and allowed an appropriate induction time before application — the induction period allows the amine and epoxy components to begin reacting, improving the applied film’s properties compared to immediate application at time zero. Follow the PPG Deft 9N-060 PDS for mixing ratio, induction time, pot life, and application viscosity specifications.

Surface preparation before priming is critical for maximum corrosion protection and adhesion. Surfaces must be cleaned, deoxidized, and conversion coated (chromate or non-chromate per the aircraft’s maintenance specification) before primer application. Applying primer over inadequately prepared surfaces reduces corrosion protection effectiveness and adhesion durability.
