The real trade-off is film thickness, cure temperature and quantity — not which one is “tougher”. Both run at our Rowlett plant, so the recommendation below is not a pitch for whichever line we happen to own.
This is a two-way decision. If the part is aluminum and anodizing is also on the table, read Cerakote vs anodizing vs powder coating → instead — anodize grows into the substrate rather than sitting on it, and that changes the reasoning. If liquid paint is the third candidate, read paint vs powder vs Cerakote →.
A thin-film ceramic-polymer coating sprayed wet from a solvent carrier, the resin loaded with ceramic filler. Cure is by series, and the series matters more than the brand name.
A dry thermoset resin applied electrostatically as charged powder, then crosslinked in an oven. No solvent, no carrier. Resin family sets the properties: epoxy for indoor chemical resistance, polyester for exterior UV, superdurable and fluoropolymer for architectural weathering, silicone for heat.
Everything else here is secondary. Powder builds two to four thousandths per surface; Cerakote runs half a thousandth to one thousandth on precision hardware. On a flat bracket nobody cares. On anything with a fit, that gap decides the job.
Film adds to both mating surfaces: four mils in a bore and four on the shaft closes eight thousandths of clearance. On a Class 2A/2B thread the pitch diameter is consumed from both flanks, so two to four mils will bind a fastener that gauged fine bare. Cerakote at one mil sits inside the tolerance of most commercial threads and slip fits.
So powder on a dimensionally sensitive part means masking threads, bores and bearing seats, or machining the coating back after — both real cost. Put the mask boundary on the print: masking for coating →.
Cure rules parts out before performance is discussed. Powder needs the whole part at 350–400°F for ten to twenty minutes: fine for a weldment, fatal for springs that relax, material tempering below the cure, assemblies holding seals, bearings, adhesives, plastics or electronics, and thin panels that distort as residual stress releases.
Cerakote H-Series cures as low as 180°F given the full two hours; C-Series and Glacier air cure with no oven at all. In service the order can reverse: standard polyester and epoxy powders sit around 200°F continuous, H-Series color stability runs roughly 250–500°F by color, and the air-cure high-temperature products are published to 1,800°F. Name your operating temperature and we will name the series or the silicone powder.
Powder needs a substrate that holds an electrostatic charge and survives the cure: steel, stainless, aluminum, castings, fabrications with a preheat or conductive primer. Not plastics or composites, and not anything that outgasses — porous castings need degassing or the film pinholes. Cerakote is wider at the low-temperature end: the air-cure products go on polymers and composites that would never see a powder oven. Neither fixes a bad surface — adhesion and corrosion life come from pretreatment, not topcoat chemistry. See surface prep, masking and blasting →. If the drawing wants an anodic or conversion coating, that is the plating side at glecoplating.com.
Impact and gouge. Film thickness is armor. Four mils of powder absorbs a dropped-tool strike a one-mil ceramic film passes straight to the substrate. Cerakote publishes 160 in-lb impact and 9H scratch hardness — excellent for a thin film, but still a thin film.
Abrasion. Ceramic loading gives Cerakote a hard, low-friction surface that takes repeated sliding contact. Thick polyester powder scuffs and mars more readily.
Corrosion. Powder’s thick continuous film is a strong barrier when pretreatment is right. Cerakote Elite publishes 4,000+ hours B117; H-Series salt spray is rated qualitatively by color. Both lose to edge coverage before chemistry, so break sharp edges — the design guide → covers radii, hang points and drain holes.
Chemicals. Epoxy powder is hard to beat indoors; Cerakote’s published resistance runs excellent to fair by reagent and color. Name the chemical and concentration at RFQ.
Powder wins on breadth and matching: thousands of stock colors, custom formulation at volume, gloss from dead flat to high, and real texture — wrinkle, hammertone, sand. It is where a specific RAL, an FS 595 chip or an OEM color is matched with confidence, and where AAMA 2603/2604/2605 weathering classes live.
Cerakote is a fixed catalog, mostly low-gloss military and industrial tones. Ceramic loading constrains pigment, so an exact RAL or FS 595 hit should not be promised without an approved sprayed panel. It does do stencilling and camouflage powder cannot practically produce. Legends over either coating are a separate operation: silkscreening →.
The curves run opposite. Powder is cheap per part once the line moves — overspray reclaimed, parts hung many to a bar, cure in minutes — so price falls hard with quantity. Cerakote is low-volume, high-value: costly material, manual application, long cure per batch. It earns its price on small parts where the alternative is masking, post-machining, or scrapping parts that distorted in the oven. On a large panel it is the wrong tool. Compare both against liquid in powder coating vs liquid paint →.
Rework splits the same way. Powder is fully crosslinked and does not spot-repair: strip it chemically or by burn-off and blast, then recoat — another heat cycle the part may not tolerate. Cerakote can be scuffed and re-sprayed locally, and the thin film means a recoat stays in tolerance.
| If your part has this | Choose | Why |
|---|---|---|
| Threads that must gauge after coating | Cerakote | 1 mil per flank stays inside most thread tolerance |
| Close-fit bore, bearing seat, sliding surface | Cerakote | Powder closes 4–8 thou of clearance |
| Springs, or material tempering below 400°F | Cerakote | Cures at 180–250°F, or air cures |
| Assembly with seals, bearings, adhesive, plastic | Cerakote | Powder cure destroys them |
| Plastic or composite substrate | Cerakote | Powder needs charge and a survivable cure |
| Production quantity of steel or aluminum parts | Powder | Cost per part falls with volume |
| Large panel, frame, enclosure, weldment | Powder | Coverage economics and handling |
| Impact and gouge resistance | Powder | Film build is the armor |
| Exact RAL, FS 595 or OEM color match | Powder | Broader palette, proven gloss control |
| Texture — wrinkle, hammertone, sand | Powder | Cerakote has no equivalent |
| Exterior architectural weathering class | Powder | AAMA 2603/2604/2605 systems exist |
| Abrasion or repeated sliding contact | Cerakote | Hard, low-friction ceramic-loaded film |
| Expected back for repair or refinish | Cerakote | Spot repair without stripping |
| Continuous service above roughly 400°F | Depends | Air-cure Cerakote or silicone powder — ask |
| A drawing calling out a MIL or CARC system | Neither | Qualified liquid system |
Not sure where your part lands? Work through the finish selector →.
If the drawing calls out a qualified system — a MIL-PRF primer and topcoat stack, a chemical agent resistant coating, a named spec behind an FS 595 color and gloss — both are out however they perform. The spec names a system, not a property, and substituting is a deviation. Same where the part is too large for any oven, field touch-up is required, or the coating goes over existing paint. That is liquid territory: industrial liquid coating → and what is CARC coating →. To turn a callout into a process, start at the MIL-spec coating cross-reference →.
Powder, liquid paint, Cerakote, MIL-spec and CARC finishing, blasting, masking and silkscreening all run at our Rowlett facility. We have no reason to push one line, because both are ours — and the wrong call comes back to us as rework either way. Send the print with tolerances, material and heat-treat condition, and service environment. See everything under one roof → and certifications and approvals →. Anodizing, plating and passivation are the plating side, at glecoplating.com.
Usually. At about one mil it adds roughly two thousandths to pitch diameter across both flanks, which most Class 2A/2B threads absorb. Powder at two to four mils generally will not, and threads must be masked or chased. Send the thread callout and class.
Yes — aluminum, steel, stainless, titanium, and in the air-cure series polymers and composites. If what you need on aluminum is an anodic or conversion coating, that is a different process on the plating side, and the three-way comparison page is the better read.
Neither, universally. Powder’s thicker film takes impact and gouging better and is the stronger outdoor corrosion barrier when pretreatment is right. Cerakote handles abrasion, sliding wear and heat better. The failure mode your part will actually see decides it.
Not reliably. Cerakote is a fixed catalog and ceramic loading limits pigment, so an exact RAL or FS 595 hit should never be promised without an approved sprayed panel. If an exact match is contractual, powder or liquid is the right process.
For powder, almost always — the 350–400°F cure damages seals, bearings, adhesives, plastics and electronics. For Cerakote, often not: the low-bake and air-cure series exist so assemblies that cannot be taken apart still get coated. Tell us what is inside.
Per part, almost always. But the comparison is per finished part. If powder means masking every thread and bore, machining coating back off, or scrapping distorted parts, Cerakote can be cheaper on the job at a higher spray price.
Cerakote can be scuffed and re-sprayed locally, and the thin film means a recoat does not push the part out of tolerance. Powder is fully crosslinked and does not spot-repair — it is stripped and recoated, which is another heat cycle.
Tolerances, material and heat-treat condition, service environment. We will tell you which of the two the part wants — and say so if the answer is neither.
