PTFE Coating Service: AEGIS Engineering Versus Commodity Applicators

Most PTFE coating shops sell on price for small parts. AEGIS Advanced sells engineering for parts that fail in service. Both business models are legitimate. Picking the wrong one for your application is expensive. This page walks through the actual differences so you can decide which fits your job.

When commodity PTFE coating is the right call

A commodity applicator is the right choice when:

• The part is small (fits in a shoebox)
• The part is not FDA regulated
• The service environment is mild (room temperature, no chemistry, low duty cycle)
• The recoat cadence does not matter
• The lowest possible unit price wins the work

Most PTFE coating shops are excellent at this. They run high volume, they keep overhead low, and they ship reliably. If your part fits the description, AEGIS will refer you to one of them.

When AEGIS engineering is the right call

AEGIS is the right choice when:

• The part is FDA regulated and the documentation matters
• The part is too big or too heavy to ship economically
• The duty cycle is severe (continuous high temperature, abrasive, chemical attack)
• Down time costs more than coating
• You need recoat scheduling, dimensional inspection, and predictable budget over multiple years
• The part has to be coated in place because it is embedded in operating equipment

Side by side comparison

Capability	Commodity applicator	AEGIS Advanced
FDA compliance letter on every job	Sometimes	Always
Validation file documentation package	Generic spec sheet	Per job records: batch numbers, cure profile trace, dimensional inspection
Field deployable service	No	Yes, North America wide
In situ heat activation cure	No	Yes, patent pending equipment
Maximum roll face length	Typically 12 feet (oven limit)	60 feet with in situ cure
Multilayer fluoropolymer systems	Single layer typical	Multilayer primer plus top coat tuned per application
Cleaning chemistry resistance testing	Generic	Coupon tested against your specific cleaning chemistry
Approved vendor list onboarding	Limited	ISO 9001, insurance, OSHA records, past performance references
Recoat scheduling and inspection	Per call	Standing schedule with dimensional inspection at every cycle
Per part minimum	Low (typically under 500 dollars)	2,000 dollar floor, 10,000 dollar typical, 100,000 dollar hero projects
Patent backed technology	No	USPTO Application 19/441,842 induction cure method

The total cost question

Unit price is the wrong metric for industrial PTFE coating. Total cost of service is the right metric. Three line items drive total cost:

• Coating unit price: AEGIS is higher than commodity applicators on small parts. We do not chase that work.
• Down time during recoat: AEGIS coatings last 2 to 3 times longer than commodity PTFE in severe service. Fewer recoat events means fewer line stops.
• Freight and handling: shipping a 40 foot roll for shop coating versus AEGIS field service on site changes the freight line item by an order of magnitude.

For severe service applications, AEGIS total cost runs lower than commodity over a 36 month operating window even though our unit price is higher. We will show you the math on your specific application if you ask.

How AEGIS quotes versus how commodity shops quote

A commodity shop quotes from a part description in a few hours. AEGIS engineering reviews the part substrate, service environment, cleaning chemistry, contact medium, current coating performance, and recoat history before quoting. The quote includes the coating system specification, the cure approach, the documentation package, and the inspection regime. Quote turnaround is typically 24 hours for shop work and 48 hours for field service.

Compare AEGIS to your current applicator

If you have a current PTFE coating supplier and want a side by side evaluation on a specific part, send the part identification, current coating spec, current recoat interval, and the failure mode you are seeing. AEGIS engineering will return a written comparison showing where our system differs and what the projected service life would be on your application.
