Product properties & Features

RFE polyisocyanate is a highly effective crosslinker for adhesives based on polyurethane, natural rubber and Synthesis rubber. 
RFE polyisocyanate is also useful for improving adhesiveness of rubber-based materials. 
It Can be used as crosslinker instead of Bayer’s Desmodur RFE.

Usage

Two-component adhesive must be used with the applicable period after putting in 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%),
RFE does 4-7. Chloroprene rubber ( Rubber account for around 20%) , RFE does 4-7.
