Henkel Loctite PC 7234 Nordbak Gray High-Temperature Brushable Ceramic Coating – 2 lb Can
Henkel Loctite PC 7234 Nordbak is a high-performance gray brushable ceramic coating from Henkel’s NORDBAK wear and corrosion protection coating product line, providing exceptional resistance to extreme temperatures, abrasion, erosion, and chemical attack on metal surfaces in very high temperature service environments. The ceramic-filled formula creates a hard, dense coating film that protects underlying metal structure from the combined thermal and mechanical damage mechanisms encountered in aerospace engine components, exhaust systems, heat exchangers, and industrial high-temperature equipment.
The brushable consistency of PC 7234 enables application without spray equipment — the coating can be applied by brush or roller to complex geometries, tight-access areas, and irregular surfaces that would be difficult to coat uniformly with spray application methods. This application flexibility makes PC 7234 particularly valuable for maintenance repair coating of engine bay components, exhaust ducts, heat shields, and other hot zone structures that may not be easily removed for shop coating.
The 2 lb can provides a practical quantity for component repair coating, maintenance touch-up, and localized area coating operations where the larger container format would result in material waste due to the limited shelf life of opened containers.

Technical Information
Loctite PC 7234 Nordbak uses a ceramic-filled binder system where ceramic particles — typically alumina, silica, or silicon carbide based — are distributed throughout the polymer matrix to provide the coating’s thermal resistance and hardness. The ceramic filler particles have extremely high melting points and thermal stability, enabling the composite coating to withstand temperatures that would degrade or combust organic binder-only coatings. The ceramic particles also provide the hardness and abrasion resistance that protects the coated surface from erosive particle impingement in high-velocity exhaust gas and compressor air flows.
The polymer binder of PC 7234 is selected for thermal stability consistent with the intended service temperature range — typically an epoxy, silicone, or organoceramic binder that provides adhesion to metal substrates while tolerating the operating temperature. After application and ambient cure, some high-temperature ceramic coatings require a post-cure at elevated temperature to develop full thermal performance — the cured polymer binder is converted to a more thermally stable ceramic-like structure at the cure temperature, improving temperature resistance beyond that of the ambient-cured film.
Surface preparation before applying PC 7234 is critical for adhesion in high-temperature service — surfaces must be clean, dry, and free of all oils, rust, and loose scale, typically by abrasive blasting to the required surface profile. Contaminated surfaces prevent the coating from bonding adequately to withstand the thermal and mechanical stresses of service.

Frequently Asked Questions
Q: What is Loctite PC 7234 Nordbak?
A: PC 7234 is a gray high-temperature brushable ceramic coating for metal surfaces in very high temperature service — providing thermal resistance, abrasion protection, and corrosion resistance in engine and exhaust applications.
Q: MPN for Loctite PC 7234 2lb can?
A: MPN is 235601.
Q: Why is PC 7234 called a ‘ceramic’ coating?
A: The ceramic designation refers to the ceramic particle filler (alumina, silica, or silicon carbide) in the coating that provides its extreme temperature resistance and hardness — ceramic particles have very high melting points, enabling the coating to survive temperatures that would destroy organic coatings.
Q: Does PC 7234 need a post-cure at elevated temperature?
A: Some Nordbak ceramic coatings benefit from elevated temperature post-cure to develop full thermal performance. Consult the Henkel PC 7234 TDS for cure procedure requirements.
Q: What surface preparation is needed?
A: Abrasive blasting to clean, dry, oil-free surface with the required surface profile for maximum adhesion. Contaminated surfaces significantly reduce high-temperature coating adhesion durability.
