Tailored solutions for metalworking and industrial manufacturing — from prototypes to production batches.
Formulated chemical systems that remove paint while protecting the substrate, with operational safety, repeatability, and reduced environmental impact in mind.
Controlled, uniform finishes compatible with painting, coating, bonding and other downstream treatments.
Support on process selection, trials, acceptance criteria and hands‑on implementation.
Case-by-case assessment for mixed or sensitive alloys, including trials when needed.
A simple, controlled workflow designed to reduce risk, lead time, and rework.
Output: a technical proposal with the safest and most predictable process route.
Output: validated parameters before scaling to a batch.
Output: a clean, predictable surface ready for the next step.
Output: less rework, less variability, and more control in your process.
Standardised procedures, sustainability focus, and consistent outcomes.
Controlled sequences and parameters to reduce variability.
Safety-first practices and waste reduction as a default.
Monitoring and records to keep lots consistent.
Fast turnaround aligned with industrial constraints.
Clean, predictable surfaces ready for coating and finishing.
Paint stripping, metal surface preparation and cleaning, technical consulting. DecAlloy is much more than a paint stripping company — it is an industrial innovation partner. We develop sustainable solutions for the cleaning and treatment of metal surfaces, combining high technical performance with environmental responsibility.
DecAlloy was founded by two professionals with backgrounds in industrial innovation. A renowned international partner adds industrial scale and global experience — aligned with the same commitment: effective, safe and more sustainable solutions.

Quick answers to the most common questions before starting a service.
We work with a broad range of coatings (e.g., powder coating, liquid paints, primers and clear coats). The initial assessment confirms the best solution and sequence for your parts.
Yes, provided the right chemistry and controlled parameters are used. For critical cases, we recommend a trial to validate compatibility and surface finish.
When risk is higher (unknown coating, sensitive alloy, strict finish requirements), a trial reduces variability and rework before scaling up.
It depends on part geometry, coating type, and volume. After assessment, we provide a clear lead time aligned with your urgency.
We prioritise controlled processes, safe handling practices, waste minimisation, and careful solution selection — maximising performance without compromising operational safety.
