Frequently Asked Questions

Find answers about our coating processes and technical capabilities

Can Cerakote maintain visual uniformity across large production runs?

Yes. ColoradoKote has maintained Delta E 1.5 color consistency across programs exceeding 20,000 parts with zero quality issues. This consistency comes from controlled process variables: calibrated HVLP equipment, documented spray parameters, temperature-controlled curing, and spectrophotometer verification on every lot. Material batch tracking ensures coating chemistry is consistent, and our AS9100 quality system prevents the process drift that causes color variation in high-volume production.

Does Cerakote seal the porosity in AM parts?

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.

How does sandblasting prepare aerospace components for Cerakote?

Aerospace components are blasted to SSPC-SP 10 near-white cleanliness at 80-100 PSI using media selected for the specific alloy. Aluminum, titanium, stainless steel, and Inconel each receive tailored blast parameters to achieve optimal 2-4 mil anchor profile without hydrogen embrittlement risk or surface damage. The entire process is documented per AS9100 with traceable media certifications, pressure readings, and before/after surface condition records.

Does passivation work on 3D-printed stainless steel parts?

Passivation is especially important for additively manufactured stainless steel, which often retains more free iron and surface contamination from the printing and post-processing steps than wrought material. The ASTM A967 acid bath removes these contaminants and brings chromium to the surface, restoring full corrosion resistance. The process follows complex AM geometries with no dimensional change, preserving the precision your additive build achieved.

Can ColoradoKote coat marine engine room components?

Yes. Engine room components face heat, fuel and oil exposure, salt atmosphere, and vibration that create a multi-threat environment for coatings. Cerakote's temperature range from -40°F to 2,000°F handles exhaust and engine heat, while its chemical resistance protects against fuel, lubricants, and coolant. The 9H hardness and impact resistance of 160/160 inch-pounds withstand the tool contact and vibration typical of marine engine rooms.
