A novel manufacturing method developed and patented for two-component room-temperature
curing of polyurethane resins (PU resins) using blocked polyisocyanates
( Reference)
- All-aliphatic type:A PU resin composed of an imidazole-blocked aliphatic polyisocyanate and an aliphatic polyamine (Patent No. 6624469).
- Aliphatic/Aromatic type:A PU resin composed of a pyrazole-blocked aromatic polyisocyanate and an aliphatic polyamine (Patent No. 6716818).
- All-Aromatic type:A PU resin consisting of a specific aromatic blocked polyisocyanate and an aromatic primary diamine (Patent application in progress)
Our technology provides a very safe manufacturing method for highperformance PU resins containing no isocyanate groups, with the reaction proceeding quantitatively at room temperature. We are confidant this method can be commercialized across a wide range of applications.
We are currently seeking joint development partners with expertise in downstream and applied technologies
