MOD Case-study
Reverse Engineering a Proprietary MOD Coating Specification Without Triggering Revalidation
Engineering Certainty Into a Safety-Critical Supply Chain
How Marcote identified, validated and replicated a proprietary coating system for a defence contractor, avoiding costly requalification and protecting programme timelines.
THE CHALLENGE
When a Specification Isn’t a Specification
The technical drawing referenced a coating system unique to the incumbent supplier which was not of an industry-recognised standard.
This created immediate risk:
- No published product data
- No material transparency
- No defined performance benchmark
- Risk of triggering a £100,000+ validation process
- Potential 12+ month approval delay
- Testing protocols
- Documentation requirements
- Audit processes
- Programme delay implications
THE REQUIREMENT
The Contractor Needed Proof, Not Assumptions
To avoid a full requalification programme, we needed to demonstrate that our proposed system was:
✔ Chemically identical, or
✔ Functionally equivalent
Across:
- Adhesion
- Thickness tolerance
- Cure profile
- Friction performance
- Corrosion resistance
- Durability
How We Mitigated Validation Risk
| Validation Risk | Marcote Response |
|---|---|
| Unknown chemistry | Reverse engineered analysis |
| No transparency | Supplier collaboration |
| Performance uncertainty | Measured benchmarking |
| Audit risk | Documented traceability |
OUR APPROACH
Structured Technical Investigation
A controlled, evidence-led process designed to validate coating equivalency and protect regulated defence supply chains.
Coating System Analysis
Detailed evaluation of the existing applied coating.
Material Identification
Cross-referencing fluoropolymer systems and proprietary naming.
Performance Benchmarking
Testing thickness, adhesion, cure behaviour and functional performance.
Technical Evidence & Documentation
Delivering auditable proof of equivalency.
THE OUTCOME
Programme Protected. Risk Mitigated.
Our evidence-led approach confirmed coating equivalency, supporting compliance requirements while maintaining operational integrity across a safety-critical supply chain.
Equivalent coating system validated
Specification integrity maintained
No safety compromise
No unnecessary requalification triggered
Programme timeline preserved
Commercial impact
Validation programmes in regulated sectors can exceed £100,000 and take over 12 months. Avoiding unnecessary revalidation protects both budget and operational readiness.
