ADIPRENE LF 1930A is a TDI-terminated polyester prepolymer having very low free TDI content. This prepolymer also has low viscosity, which allows it to be processed at reduced temperature for better heat stability and longer pot life. It yields a high performance 93 Shore A hardness elastomer when cured with 4,4'-methylene-bis-[o-chloroaniline], commonly called MBCA. Features of ADIPRENE LF 1930A include:
