Production & manufacturing
Amine, metal, and trimerization catalysts engineered for flexible foam, rigid insulation, low-odor automotive, and CASE systems.
R&D & analysis
From high-resilience seating to memory foam and rigid insulation panels — the right catalyst package for every system.
Compliant by design
REACH- and RoHS-compliant grades, mercury- and lead-free chemistry, and low-odor systems for sensitive applications.
Innovation, applied
One thing, done deeply — the chemistry that decides how a polyurethane behaves.
Applications
Our catalysts, additives, and curing agents run through the systems that make modern comfort, mobility, and construction.
Molecular engineering
A catalytic centre — a tertiary amine nitrogen or an organometallic site — bonded to the ligands that set its reach, its speed, and what it will and won't react with. Small changes to that structure are what separate a fast-gel grade from a delayed-action one, or a foam catalyst from an epoxy accelerator.
The catalog
From gel and blow amines to trimerization and metal catalysts — pick an application and the catalog narrows to the grades that fit. Each card links to a full datasheet.

How catalysis works
Every polyurethane is a race between two reactions: the blow (water + isocyanate → CO₂, which lifts the foam) and the gel (polyol + isocyanate → polymer, which sets it). A catalyst lowers the activation energy of one or both — so the same molecules cross to product far more readily, at the rate and in the order you want.
