| ADIPRENE LF 1900A 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, 90 Shore A hardness elastomer when cured with 4,4′-methylene-bis-(o-chloroaniline), commonly called MBCA. Features of ADIPRENE LF 1900A include: Low Free TDI Content Low Viscosity Long Pot Life High Tear and Tensile Strength&& |
