    Description

    MOFAN 5 is high active polyurethane catalyst, mainly used in the fasting, foaming, balance the overall foaming and gel reaction. It is widely used in the polyurethane rigid foam including PIR panel. Because of strong foaming effect, it can improve the foam liquidity and product process, compatible with DMCHA. MOFAN 5 also can compatible with other catalyst except polyurethane catalyst.

    Application

    MOFAN5 is refrigerator, PIR laminate boardstock, spray foam etc. MOFAN 5 can also be used in TDI, TDI/MDI, MDI high resiliency (HR) flexible molded foams as well as integral skin as well as microcellular systems

    FAQ

    I need a very strong gel catalyst for high-resilience cold-cure foam with fast demold. Is MOFAN 5 suitable?

    Yes, it’s one of the strongest gel catalysts available. Use 0.1–0.25 phr to achieve demold times under 3 minutes.

    My epoxy grout is too slow at 5°C. How can MOFAN 5 accelerate it?

    Add 0.5–2% by weight on resin; it dramatically reduces cure time even at low temperatures.

    Can MOFAN 5 be used in polyurethane casting systems to reduce cure time without increasing exotherm?

    To a limited extent; but its high activity may cause exotherm spikes. Use a mixture with MOFAN 8 for better control.

    What’s the best way to avoid foam splitting when using high levels of PMDETA?

    Always combine with a blowing catalyst like MOFAN A1 at a ratio of 1:0.3 (PMDETA:A1) to balance gel and blow.

    Does MOFAN 5 cause severe yellowing in aromatic PU systems?

    Moderate yellowing; for white or light-colored parts, reduce the level or use a UV stabilizer.

    My polyurethane adhesive for shoe soles has poor green strength. How to improve?

    Add 0.2–0.4 phr MOFAN 5 to increase initial viscosity buildup, giving better handling after pressing.

    Can MOFAN 5 be used in RIM (reaction injection molding) formulations?

    Yes, its high reactivity is ideal for fast RIM cycles; typical dosage 0.3–0.7 phr.

    What catalyst combination gives the shortest demold time for integral skin foam?

    MOFAN 5 (0.15 phr) + MOFAN 33LV (0.4 phr) provides demold in 2–2.5 minutes at 50°C.

    I have a rigid spray foam that sags on vertical surfaces. Can MOFAN 5 increase thixotropy?

    Indirectly, by faster gelation it reduces sag. Increase to 0.2–0.3 phr for better vertical stability.

    Is MOFAN 5 volatile enough to cause amine odor in final foam?

    It has moderate volatility; post-curing at 60°C for 2 hours will eliminate most residual amine.
