    Description

    MOFAN DPA is a blowing polyurethane catalyst based on N,N,N'-trimethylaminoethylethanolamine.  MOFAN DPA is suitable for use in producing molded flexible, semi-rigid, and rigid polyurethane foam. In addition to promoting the blowing reaction, MOFAN DPA also promotes the crosslinking reaction between isocyanate groups.

    Application

    MOFAN DPA is used in molded flexible, semi-rigid foam, rigid foam etc.

    FAQ

    I produce low-odor waterborne polyurethane coatings. How can DPA help?

    DPA is a low-odor, reactive amine that reduces amine smell during application and after film formation.

    My polyurethane elastomer has poor tear strength. Can DPA improve it?

    Yes, its diisopropanolamine structure can increase crosslink density and tear resistance when used at 0.2–0.5 phr.

    What is the typical dosage for DPA in a polyurethane sealant to improve adhesion to concrete?

    0.3–0.6 phr; it enhances wetting and chemical bonding to mineral surfaces.

    Can DPA be used as a co-catalyst in polyurethane spray foams to reduce odor?

    Yes, it helps lower the overall amine volatility; often blended with MOFAN 33LV.

    My polyurethane adhesive for PVC has poor heat resistance. How to improve?

    Add DPA (0.4 phr) to increase the crosslinking density, raising the heat deflection temperature.

    Is DPA compatible with moisture-cure systems?

    It can be used, but because it contains OH groups, it will react with isocyanate. Use in two-component systems only.

    How does DPA compare to triethanolamine (TEOA) as a crosslinker?

    DPA is a better catalyst and milder crosslinker; TEOA is mainly a crosslinker with weak catalytic activity.

    My polyurethane foam for packaging has a slow recovery after compression. Can DPA fix this?

    Yes, increase DPA to 0.2–0.3 phr to enhance the elastic network formation.

    Can DPA be used in epoxy systems to improve flexibility?

    Yes, as a modifier it can reduce brittleness without slowing the cure.

    What is the shelf life of a polyol blend containing DPA?

    At least 6 months when stored in a dry, sealed container.
