In this paper, several curing agent of polyurethane were synthesized. Influences of solid content and dosage of TDI tripolymer on different PU adhesion high initial bonding strength were discussed.
A polyisocyanate curing agent, which is mainly composed of toluene diisocyanate (TDI) trimer, was prepared in the presence of the base metal carboxylate K-1000.
