Baydur STR/C 675 is a polyurethane medium to high density structural RIM system used in the Long Fiber Injection (LFI) technology.

The Baydur STR/C 675 system is used in an open mold process with varying levels of fiberglass reinforcement depending on the property requirements needed. The system has a long gel time, yet fast cure time, which makes it well suited for large part applications.

The Baydur STR/C 675 system is supplied as two reactive liquid components. Component A is a polymeric diphenlymethane diisocyanate (PMDI), and Component B is a formulated polyether polyol system. As with any product, use of the Baydur STR/C 675 system in a given application must be tested (including field-testing, etc.) in advance by the user to determine suitability.
