- ▸ Primary gelling catalyst for flexible, rigid, and microcellular polyurethane
- ▸ Accelerator of the isocyanate-polyol (urethane) network-building reaction
- ▸ Catalyst-package base, typically supplied as a glycol or amine solution/blend
- ▸ Co-catalyst with blowing amines to tune the blow/gel balance
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Few catalysts are as ubiquitous in polyurethane as triethylenediamine. The caged diamine exposes two highly basic, sterically open nitrogens that strongly push the gel (urethane) reaction, building molecular weight and load-bearing structure as the foam rises. Because neat TEDA is a low-melting flammable solid that reacts very fast, it is almost always handled as a solution or blend, commonly in glycols such as dipropylene glycol or in amine carriers, to ease metering and moderate onset. It anchors catalyst packages for flexible slabstock and molded foam, rigid insulation, and microcellular elastomers, typically paired with a blowing catalyst to set the blow/gel balance. The trade-off is its speed: undiluted TEDA can gel a system before it fills a mold, which is exactly why diluted grades and delayed-action derivatives exist
