It Can be used as crosslinker instead of Bayer’s Desmodur RFE.

The length of applicable period is not only related to the polymer content of adhesive, 
but also other relevant components ( like resin, Antioxygen, plasticizer, solvent, etc.

When close to the applicable period, usually a few hours or one working day, adhesive becomes more difficult to operate, 
and viscosity rises soon.

Finally, it becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane ( Polyurethane account for around 20%),
