Tris(4-isocyanatophenyl) thiophosphate / RFE / TPTI

Cas No.: 4151-51-3
MF: C21H12N3O6SP
Alternative to Bayer’s Desmodur RFE
Common packing: 0.75kg/bottle, total 20 bottles in one carton box, 180kg/barrel.
Note: It should be stored in the original sealed jar under 23℃, the products can be preserved stable for six months. All Cross-linker series products are very sensitive to the moisture; it will produce carbon dioxide and insoluble urea in the reaction with water. If exposure to the air or light, it will speed up color changes of products, But the practical function will not be affected.

Properties & Applications & PackagesInquiry
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. 

Two-component adhesive must be used with theapplicable 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.
