ColoradoKote

Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.

Method

Three Stages of Polymer Coating

The same AS9100 quality system governs polymer coating operations, from surface preparation through final inspection.

Preparation
Substrate-Matched Surface Preparation

Surface cleaning and profiling are matched to the base material. Metal substrates receive blast profiling for mechanical adhesion. Polymer and composite substrates receive chemical surface activation. All preparation is documented under AS9100 protocols.

Application
Controlled Film Build

Polymer coating is applied via calibrated spray equipment in controlled layers. Film thickness is verified at each stage to achieve the specified build. Air-cure formulations eliminate the need for oven curing, accommodating oversized and heat-sensitive components.

Inspection
Performance Verification

Post-application inspection verifies film thickness, adhesion, visual appearance, and surface uniformity. Adhesion testing confirms bond integrity on the specific substrate. Full documentation accompanies every shipment with measured results.

The Polymer Coating Process

Polymer coatings form a continuous, flexible film that absorbs substrate movement without cracking or delamination. ColoradoKote applies polymer coatings under the same AS9100 quality system that governs ceramic operations, delivering documented quality for gaskets, seals, sliding interfaces, and chemically exposed surfaces.

Results

What Our Polymer Coating Delivers

Polymer coatings solve problems that rigid ceramic coatings cannot address. Each result is verified through standardized testing.

Full
Chemical Resistance Rating

Polymer coatings withstand acids, alkalis, solvents, and fuels that attack unprotected substrates. The continuous film prevents chemical penetration to the base material, extending service life in harsh chemical environments.

Before and after Cerakote coating comparison
Low
Coefficient of Friction

Polymer coatings provide lubricious surfaces that reduce wear on sliding interfaces. The low friction coefficient minimizes heat generation and mechanical stress on dynamic components requiring smooth, consistent operation.

Flex
Substrate Conformability

Polymer films conform to substrate movement, vibration, and thermal cycling without adhesion loss or cracking. This flexibility makes polymer the correct choice for gaskets, seals, and components subject to repeated dynamic stress.

Frequently Asked Questions

Find answers about our coating processes and technical capabilities

How long does passivation protect stainless steel from corrosion?

The corrosion protection from passivation is inherent to the stainless steel itself. By removing contaminants and maximizing surface chromium, passivation restores the material to its designed corrosion resistance, which can last the lifetime of the part in appropriate environments. For environments that exceed stainless steel's natural limits, adding a Cerakote topcoat at 0.5-2 mils extends measurable salt spray resistance to 3,000 hours per ASTM B117.

Can ultrasonic cleaning remove transmission fluid and differential oil from automotive drivetrain parts?

Yes. Drivetrain components including transmission cases, differential housings, and transfer case components accumulate gear oil, ATF residue, and metallic wear particles in every internal surface and crevice. Ultrasonic cavitation penetrates bearing bores, oil channels, and casting details to remove these contaminants completely. For drivetrain components being Cerakote coated for corrosion protection and heat management, thorough removal of petroleum contaminants is essential to prevent fish-eye defects and adhesion failures.

Can Cerakote post-processing make AM medical device housings suitable for clinical environments?

Yes. Raw AM surfaces harbor bacteria in their inherent porosity and texture, making them unsuitable for clinical settings. Cerakote seals surface porosity and reduces roughness from Ra 8-15 micrometers to below 3 micrometers, creating a smooth, cleanable surface compatible with hospital disinfectants and autoclave sterilization. The sealed surface prevents microbial adhesion while the coating withstands thousands of cleaning cycles without degradation. This transforms AM builds into clinical-grade components.

Does ColoradoKote offer the full surface preparation stack for aerospace components?

Yes. We run the complete preparation-to-coating sequence in-house: ultrasonic cleaning removes machining fluids and contaminants from blind holes and internal passages, chemical conversion coating (chromate or non-chromate) provides the adhesion-promoting base layer, and Cerakote ceramic coating delivers the final corrosion and wear barrier. Running this full stack under one AS9100 quality system eliminates handoff risk between multiple vendors and compresses your lead time.

Does Cerakote add significant weight to lightweight AM parts?

No. At 0.5-2 mils thickness, Cerakote adds negligible weight compared to powder coating at 4-6 mils. For AM parts designed with topology optimization and lattice structures to minimize mass, this thin-film approach preserves the weight savings of additive manufacturing while adding corrosion, wear, and chemical resistance. The weight impact is typically measured in fractions of a gram on small-to-medium components.
