    FAQ

    I need to pass VDA 278 for automotive foam. Is MOFAN 204 qualified?

    Yes, MOFAN 204 is a low-emission, reactive catalyst designed to meet the strictest fogging and VOC limits.

    My high-resilience foam has inconsistent density. How can MOFAN 204 improve process stability?

    It provides a delayed action, allowing better mold filling before gelation, leading to more uniform density.

    What is the recommended usage level in a cold-cure molded foam?

    0.2–0.5 phr, often used together with a low-odor co-catalyst like MOFAN 77.

    Can MOFAN 204 be used in polyurethane adhesives for food packaging?

    Yes, after full cure the residual amine extractables are below 5 ppm, compliant with FDA indirect food contact.

    My polyurethane sealant has poor green strength. Can 204 improve it?

    No, it is delayed; use a faster catalyst like MOFAN 8 for early strength.

    Is MOFAN 204 compatible with water-blown systems?

    Yes, it works well with water as a blowing agent, especially in low-density formulations.

    How does MOFAN 204 compare to 204?

    Direct replacement; same performance and physical properties.

    My elastomer parts show surface stickiness after demolding. Can 204 eliminate it?

    Yes, its reactive nature ensures that the surface is fully cured and non-tacky.

    What is the shelf life of MOFAN 204 in a polyol premix?

    At least 6 months under dry nitrogen; avoid acidic polyols.

    Does MOFAN 204 cause any discoloration in light-colored foams?

    No, it is virtually non-yellowing and suitable for white or pastel products.
