Corrosion Resistance for Industrial

Marine components face the most aggressive natural corrosion environment: constant salt water contact, salt spray atmosphere, and UV exposure. Cerakote's 3,000-hour ASTM B117 salt spray rating provides the highest thin-film corrosion protection available for marine hardware. Our chemical conversion coating for aluminum and passivation for stainless steel substrates provide additional protection layers before Cerakote application, creating a comprehensive marine corrosion defense system.

Yes. Raw AM parts, particularly polymer SLS and MJF builds, have surface and near-surface porosity that allows moisture and chemical ingress. Cerakote fills and seals these pores during application, creating a continuous barrier layer at 0.5-2 mils thickness. This sealing effect provides corrosion protection exceeding 3,000 hours salt spray on metal AM parts and chemical resistance on polymer AM parts that raw printed surfaces cannot achieve.

Yes. Our spectrophotometer-verified color matching creates a documented color standard for your program that we reference on every production run. Delta E within 1.5 ensures parts coated today match parts coated months or years from now. This level of consistency matters for aircraft cabin interiors, branded equipment, and any application where batch-to-batch color variation is unacceptable.

Chemical conversion coating creates a chemically bonded interlayer between the substrate and Cerakote. Under abrasive service, this interlayer prevents the delamination that occurs when coatings are applied directly to bare metal. The result is that even when the surface layer of Cerakote wears under sustained abrasion, the remaining coating stays bonded rather than peeling away in sheets. ColoradoKote runs both processes in-house under one quality system, ensuring the interlayer is applied to a freshly prepared surface without contamination.

Yes. Oil and gas equipment programs often span years, with replacement and expansion parts ordered long after the original batch. We retain the spectrophotometer data, formulation records, and Delta E measurements from every order so your custom color is exactly repeatable. Parts produced two years apart are verified to Delta E 1.5 against the original standard, ensuring consistent visual identification across your entire installed equipment base.
