What is on-site coating cure?

on-site coating cure means curing a heat-activated coating where the part lives, using portable on-site cure instead of a shop oven. AEGIS uses the on-site cure to bring the coating substrate to cure temperature, hold it, and let the part cool in place.

Why does in-situ cure matter for fluoropolymer coatings?

PTFE, PFA, and FEP coatings need 400 to 700 degrees Fahrenheit to fuse properly. Traditional shops require parts to fit in a curing oven, which excludes any roll over about 12 feet long or any non-removable fixture. In-situ cure removes that constraint and lets AEGIS coat parts that have to stay where they are.

What size parts can AEGIS cure on site?

There is no fixed upper limit on part size for in-situ cure. AEGIS has coated and cured rolls up to 60 feet face length and structural steel sections that could not be removed from operating facilities. The constraint is access for the cure equipment, not part size.

How accurate is the temperature control?

the on-site cure maintains substrate temperature within plus or minus 10 degrees Fahrenheit across the cure window. We instrument the part with surface sensors and adjust on-site cure live to follow the cure profile.

Is in-situ heat cure available in the US and Canada?

AEGIS is the only commercial coating shop in the US and Canada offering on-site cure for heat-activated industrial coatings. Service is dispatched from Elkton MD with crews available for projects across North America.

On-site coating cure for industrial assets

Some industrial assets cannot come to a coating workshop. AEGIS brings the coating to them. We prepare, coat, and cure on-site, in your maintenance window, with no oven and no removal, for welded structural steel in service, large pump bodies and housings, paper machine rolls in production, and long shafts that risk distortion in an oven.

Why on-site cure matters

For many assets, removing the equipment is the most expensive part of a coating job. Disassembly, rigging, transport, reinstallation, and recommissioning often cost more than the coating itself, and the asset is offline for days or weeks. On-site cure collapses that whole chain into a single field cure cycle inside your outage window.

What AEGIS brings to your facility

Mobile surface prep

The clean, bond-ready surface preparation that makes the coating last, delivered on-site with no hazardous-waste stream.

On-site cure that holds tolerances

Cured in place at the right temperature while protecting the dimensions of long rollers, shafts, and precision parts.

The crew that applied it cures it

AEGIS technicians trained on your specific coating chemistry and substrate run the full field job.

Documented quality before we leave

Coating thickness, hardness, and cure recorded at the asset, with a job package delivered on handover.

Where on-site cure is the right answer

Welded structural steel in service in marine, refinery, and chemical-plant atmospheres.
Permanently installed pump bodies and impellers too large or embedded to ship economically. Shippable pump components run through our workshop on a 5 to 7 day standard turnaround.
Long rollers and shafts that risk distortion in a convection oven, where on-site cure preserves dimensional tolerance.
Components that physically cannot fit a traditional oven, including large castings, oversized assemblies, and paper machine rolls beyond 60 feet face length.
Wellhead components in production where shutdown for removal is impractical.

What we need to plan a field job

Asset details: substrate, geometry, current condition, and current coating if any.
Service environment: chemistry, temperature, pressure, and what is currently failing.
Access constraints: power availability, work envelope, hot-work permits, plant safety procedures.
Outage window: maintenance schedule and tolerable downtime.
Quality requirements: any specific NACE, ISO, FDA, or customer spec.

How a field job runs

Coating review. We spec the system and field approach within one business day.
Site survey. We confirm access and constraints and lock the work plan.
Mobilization. Mobile rigs arrive on schedule with documented procedures.
Surface prep and coating. Prepared and coated to spec on the asset.
Cure and verification. Cured in place, then thickness, hardness, and cure documented before demobilization.

Frequently asked

How long is the asset down?

For most structural and large pump-body work the job fits inside a normal maintenance outage. We give you the exact required downtime when we scope it.

Does the whole line have to shut down?

Usually just the asset being coated. Adjacent equipment can typically stay live, depending on hot-work permitting at your facility.

Can you work in a hazardous area?

Field equipment can be set up for hazardous-area service depending on classification. Tell us the area classification and we spec accordingly.

How do I know the cure is good?

Coating thickness, surface hardness, cure, and a visual inspection are recorded at the asset and delivered as a job package before we demobilize. If a touch-up is ever required, we resolve it under the original job order at no additional cost.

Cure your coating on-site

Send us the asset and the outage window. We will spec a field cure that fits inside it.
