ADIPRENE LFG 740D is a TDI-terminated polyether prepolymer that, when cured with 4,4'-methylene-bis-(o-chloroaniline),MBCA, yields a 75 Shore D elastomer. The features of ADIPRENE LFG 740D include:
LFG 740D offers improved safety during handling and processing over conventional-type prepolymers due to the low content of free TDI, less than 0.1%. |
