AkzoNobel Laminar X-500 Black PWA 36013 Conductive Coating – 1.25 Quart Kit

AkzoNobel Laminar X-500 is a black, electrically conductive polyurethane coating qualified to Pratt and Whitney’s PWA 36013 and DHMS C4.13 Type II specification — making it an approved conductive coating for Pratt and Whitney engine components and aerospace airframe surfaces where electrical conductivity, static charge dissipation, or specific surface resistivity performance is required. The PWA (Pratt and Whitney Approved) qualification reflects AkzoNobel’s successful demonstration that Laminar X-500 meets P&W’s rigorous aerospace coating performance requirements.

Conductive coatings like Laminar X-500 are used in aerospace applications where surfaces must form part of the aircraft’s electrical bonding and grounding system, where lightning strike protection requires conductive surface paths, or where EMI shielding of electronic equipment is achieved through conductive coating of housings and panels. The polyurethane binder provides flexibility and durability superior to epoxy for conductive coatings on surfaces subject to flexing, vibration, and impact in aerospace service.

The 1.25 quart kit provides a practical quantity for component coating, repair zone application, and small-area conductive coating operations where the full large-format kit would result in material waste.

Technical Information

AkzoNobel Laminar X-500 uses a polyurethane binder system loaded with conductive filler — typically carbon black, graphite, or metallic particles — that creates a network of conductive pathways through the cured coating film. The electrical surface resistivity of the cured X-500 coating is engineered to meet the PWA 36013 Type II specification range, providing reliable, reproducible electrical performance across the coating’s specified service temperature range.

The polyurethane chemistry of X-500 provides greater flexibility and impact resistance than epoxy conductive coatings — an important advantage for conductive coatings on engine nacelle surfaces, access panels, and other aerospace components subject to vibration, thermal cycling, and mechanical handling during maintenance. The flexible binder resists cracking and delamination that could interrupt the conductive coating’s electrical continuity in service.

Application requires proper surface preparation, mixing, and spray technique per the AkzoNobel Laminar X-500 product data sheet. Electrical resistivity testing of the cured coating should be performed to verify specification compliance before returning the component to service in critical conductive coating applications.

A: MPN is S05721.

Q: What is PWA 36013?
A: PWA 36013 is a Pratt and Whitney Approved (PWA) specification for conductive coatings used on Pratt and Whitney engine components and other aerospace surfaces requiring specified electrical conductivity performance.

Q: Why polyurethane vs epoxy for conductive coating?
A: Polyurethane provides greater flexibility and impact resistance than epoxy, which is important for conductive coatings on vibrating engine and airframe surfaces where epoxy could crack and interrupt electrical continuity.

Q: How is the conductive coating tested?
A: Electrical surface resistivity is measured with a resistance meter after coating cure. Results must fall within the specification range defined by PWA 36013 Type II before returning the component to service.
