AkzoNobel 463-6-4/X-306 BMS10-142 High Temperature Epoxy Coating – 1 Gallon Kit

AkzoNobel 463-6-4/X-306 is a high-temperature aerospace epoxy coating qualified to Boeing Material Specification BMS10-142 Type I, Class A, Grade A — designed for use on aircraft structural and system surfaces in engine bays, hot section areas, pylon structures, and other elevated-temperature zones where standard aerospace coatings cannot withstand the thermal environment without significant degradation. BMS10-142 qualification ensures the coating meets Boeing’s exacting requirements for thermal stability, adhesion retention, and corrosion protection at temperatures exceeding those of standard aircraft exterior surfaces.

High-temperature epoxy coatings are critical for protecting aircraft structure in the thermal zones around turbine engines — these areas experience temperatures from ambient (cold soak) to several hundred degrees during engine operation, requiring a coating system that maintains adhesion and corrosion protection through repeated thermal cycling without cracking, blistering, or delaminating. Failure of high-temperature coatings exposes bare metal structure to corrosion accelerated by the combination of heat, moisture, and combustion byproducts in the engine bay environment.

The gallon kit provides production-scale quantity for engine bay painting operations, pylon coating, nacelle interior coating, and other high-temperature zone applications requiring BMS10-142 qualified material during heavy maintenance events.

Technical Information

AkzoNobel 463-6-4/X-306 uses a high-temperature resistant epoxy binder system modified with inorganic fillers and heat-resistant pigments to provide thermal stability at temperatures beyond the capability of standard aircraft epoxy coatings. The epoxy binder’s glass transition temperature (Tg) is formulated to remain above the maximum service temperature of the coating in the application zone, preventing film softening and loss of adhesion at elevated temperatures.

The BMS10-142 Type I, Class A, Grade A classification identifies the specific thermal range, performance category, and quality grade of the coating within Boeing’s high-temperature coating specification. The grade A designation indicates the highest quality tier within the specification class, with stringent requirements for adhesion after thermal exposure, resistance to thermal shock, and corrosion resistance in the combined thermal-corrosive environment of aircraft engine zones.

Application of high-temperature coatings requires thorough surface preparation and correct curing conditions — including oven cure at elevated temperature in some specifications — to achieve the full thermal performance potential of the cured coating film. Consult the AkzoNobel 463-6-4/X-306 TDS and applicable Boeing SRM for specific surface preparation, application, and cure procedures.
