SUEN Research Technologies · Valencia, Spain
Materials science that ends in a decision
An independent laboratory and engineering team working on structural adhesive bonding, thermal and mechanical characterisation of materials, and the certification your customer is going to ask you for. We measure, we explain what the number means, and we tell you what to do next.
Adhesive bonding & EN 17460 Talk to usTwo ways people arrive here
Most enquiries are one of these two. They need different answers, so we have written them out separately rather than making you guess which half of the page applies to you.
A standard has landed on your desk
Your customer has started asking for EN 17460 or EN ISO 21368, the rail sector has moved on from DIN 6701, and nobody in the plant has done this before. The certificate is tied to the site, covers six process stages and lasts three years.
- Gap analysis against the standard, before anyone books an audit
- Procedures, records and the responsible-person role
- Laboratory evidence that the joint actually holds
You manufacture outside Europe and sell into it
Neither standard restricts certification by nationality. The certificate follows the plant, the audit happens where you produce, and the person responsible for bonding may sit in Europe. What is usually missing is not eligibility — it is a technical counterpart inside the EU.
- Yes, a non-European company can be certified to EN 17460
- We can act as your technical contact within Europe
- Testing to European standards, reported in a form your customer accepts
What we can measure
Four techniques answer most of the questions that stop a production decision. Each one is run in our own laboratory, so the turnaround is ours to commit to.
DSC
Has it fully cured? Glass transition, melting, residual enthalpy and degree of cure. The technique that settles arguments about cure cycles.
TGA
Up to what temperature can I use it? Thermal stability, decomposition, filler and volatile content — and whether a supplier has quietly changed the formulation.
DMA
How does it behave under load, hot and cold? Storage and loss modulus, damping and service temperature range of the cured adhesive or polymer.
Metallography
What does the joint look like inside? Cross-sections, bond line, porosity, coating thickness and the failure mode after a test.
The rest of what we do
Services
Six lines of work, from materials characterisation and cure-cycle optimisation to coatings development and incoming quality control.
See the service lines →R&D and innovation
Contract research on coatings, adhesives and process efficiency, run as a project with agreed deliverables — and a clear answer on who owns the results.
How we run projects →Where we come from
SUEN grew out of the paper industry: coating, drying, energy consumption and the behaviour of consumables on the machine. That applied habit runs through everything else.
Applied to your process →Tell us what you are trying to decide
A short description of the part, the adhesive and the customer requirement is usually enough for us to tell you whether this is a test, a certification project, or something you can solve without us.
