COLMAT — Carbon materials engineered for the factory

What we do

One carbon science, three shared building blocks

The COLMAT platform rests on three technological building blocks that we deploy from one market to another. This sharing is what makes each solution defensible and financeable.

We functionalise

Controlled interface functionalisation: the material’s surface profile is tuned to your specification, not fixed in advance.

We structure

Multi-scale micro-structuring: the material architecture is designed for the target performance, from nano to macro.

We hybridise

Reasoned hybridisation: carbon is combined (silicon, boron nitride, activated carbon) to reach what a single material cannot.

Materials that lift a precise ceiling

Each solution starts from your factory’s constraint, not from the material. Drop-in integration, zero line modification, zero investment on your side.

Available

Silicon-carbon batteries

High-capacity Si/C anodes. 2× the capacity of graphite, measured by Fraunhofer ISE.

Available

Low-carbon construction

Concrete additive. +22% at 24 h, strength retained at 28 days, plasticising effect — validated by CERIB.

Co-development

Lubricants

Anti-wear and extreme-pressure, zinc- and phosphorus-free. −42% wear (ASTM), EURO 7 compatible.

Co-development

Polymers & composites

Masterbatch: stiffness, impact and flow improved simultaneously — unique on the market.

Strategic horizon

Supercapacitors & inks

Printed supercapacitors for IoT, conductive and functional inks.

Strategic horizon

Sodium-ion & others

Na-ion batteries, conductive resins, sealing, functional textiles — eight fields in total.

What it changes, in data

Three gains measured by independent laboratories, following each sector’s standardised protocols. No projections, no extrapolation.

COLMAT Si/C

2× the capacity of graphite, on the same production line.

Concrete compressive strength % of reference — validated by CERIB

+22% at 24 h, gain retained at 28 days. Faster demoulding, higher throughput.

Wear under extreme pressure ASTM standardised testing

Zinc- and phosphorus-free, at very low dosage. EURO 7 compatible.

Three steps, from identified ceiling to licence

A clear framework, with no industrial commitment on your side before you have seen the results on your own parts.

Scoping

A 20-minute call to identify the performance ceiling to lift and confirm that carbon chemistry can address it. Under NDA if needed.

≈ 2 weeks

Validation on your parts

We formulate a sample tuned to your specification. You test it on your line, using your protocols and your acceptance criteria.

≈ 3 to 6 months

Licence & industrialisation

Licence agreement on the validated scope. You produce at your scale; we retain ownership of the technology and provide material support.

volume-dependent

Concrete, not promises

Third-party validated

Our gains are measured by independent laboratories — Fraunhofer ISE, CERIB — against each sector’s standards. Not laboratory promises.

Drop-in, zero CAPEX

The material integrates into your existing line, with no process change and no investment. You keep your industrial scale.

A platform, not a product

Three shared technological building blocks, tunable to your specification. A defensible solution that does not become a commodity.

A licensing model

We own and licence the technology. You access the performance without internalising R&D — and without ever depending on transferable know-how.

Do you have a performance ceiling
that a carbon material could lift?

We bring the material innovation, you keep your industrial scale. A 20-minute call is enough to see whether it applies to your line.
