Corrosion resistant coatings
Corrosion resistant coatings prevent corrosive materials from aggressively reacting with parts.
Why Corrosion Resistant Coatings?
Corrosion resistant coatings, distinct from chemical resistant coatings, tend to focus on providing a protective barrier against salt water and atmospheric corrosion.
The objectives of corrosion resistant coatings are to prolong the life of your components, reduce downtime, improve safety and reduce galling.
The corrosion resistant coatings applied by Marcote have operating temperatures in the range of -70oC to + 200oC and have a coating thickness range from 60 microns to 5mm.
Components Commonly Coated with Corrosion Resistant Coatings:
- Nuts & Bolts
- Pipe Work
- Vessels
- Springs
- Housings
- Valves
Whilst the most obvious type of corrosion seen is that of steel rusting, both lesser grades of stainless steel and aluminium can too corrode.
The physical barrier is where a non-porous or non-permeable coating prevents the corrosive liquid – water in the case of atmospheric corrosion – from getting through the coating. In these situations, Marcote uses fluoropolymers for their longevity.
Static dissipative versions (often mistakenly called conductive coatings) can also be offered by us where static dissipation and corrosion protection is required.

Corrosion Resistant Coating FAQs
Corrosion resistant coatings are designed to protect components from degradation caused by moisture, salt, atmospheric exposure, and corrosive environments. They form a physical barrier that prevents corrosive agents from reacting with the substrate, extending component life and reducing maintenance and failure risk.
Corrosion resistant coatings primarily protect against water, humidity, salt spray, and atmospheric corrosion, whereas chemical resistant coatings are designed to withstand direct exposure to aggressive chemicals such as acids and solvents.
In some environments both corrosion and chemical exposure are present, and Marcote can specify coatings that address both requirements.
Marcote’s corrosion resistant coatings typically operate across a wide temperature range, from approximately –70°C up to +200°C, depending on the coating system and application requirements.
Coating thickness can range from around 60 microns up to 5mm, offering flexibility for both precision parts and heavy-duty protection.
Corrosion resistant coatings are commonly applied to:
Nuts and bolts
Pipework
Springs
Housings
Valves
Vessels
They are particularly valuable for components exposed to outdoor environments, washdown processes, marine conditions, or high humidity.
Yes. Many corrosion resistant coatings can also provide additional performance benefits such as:
Reduced friction
Impact and abrasion resistance
Anti-galling properties
UV resistance
This allows corrosion protection to be combined with improved mechanical performance.
Marcote ensures long-term corrosion protection by:
Selecting non-porous, non-permeable coating systems
Matching coating thickness to environmental severity
Applying coatings under controlled conditions
Carrying out inspection and quality checks on every job
Marcote operates under ISO 9001 quality management systems, ensuring consistent, repeatable results.
