Baxenden Trixene Aqua BI 220

[Trixene Aqua BI 220]

Trixene Aqua BI 220 is a unique waterbased blocked isocyanate based on hexamethylene diisocyanate trimer (HDI Trimer) and dimethylpyrazole (DMP).  Trixene Aqua BI 220 allows for the formulation of 1K reactive waterborne polyurethane system.  Trixene Aqua BI 220 unblocks at 120C, at which point HDI Trimer is released and the coating then proceeds like a traditional polyurethane system.  Trixene Aqua BI 220 can be used as the sole cross linker, or can be used in conjunction with melamines.  Suitable for textiles, leather, glass, and paper.
