CUCAT-DG01/DG02

    CUCAT-DG01 and CUCAT-DG02 are both versatile effective catalysts, recommending to TDI/MDI+PPG+MOCA and MDI+PPG+BDO systems for PU CASE applications. They are proprietary mixed organic metallic complex specially formulated to be a substitute to mercury catalysts without the toxicity (heavy metal, PAH, phthalate plasticizers) concerns. They can pass China and EU environmental regulations.

    Applications:

    They are general purpose catalysts, which are recommended to be used in 2-component polyurethane systems, especially in  TDI/MDI+PPG+MOCA and MDI+PPG+BDO systems, for diverse PU CASE applications, such as PU wheels, cyclones, non-solvent PU leathers, PU flooring coatings, adhesive and sealants.

     

    Features & Advantage:

    CUCAT-DG01 / CUCAT-DG02 is the newest substitute of organic mercury catalyst, developed for PU non-foam applications. It has excellent catalytic selectivity of the reaction between isocyanates and hydroxyl/amino group, without catalyzing to the reaction between isocyanates and moisture, performs very similar with organic mercury of initial viscosity, gel point and post-cure time. The unique characteristics are following:

    ◢ Excellent flowability. CUCAT-DG01 would not improve initial viscosity of mixtures that make the mixtures can flow into mold freely and quickly.

    ◢ Stability of pot life. Increase dosage would not shorten the pot life obviously, the pot life keep similar even if the dosage is double.

    ◢ Fast curing. The strength and demoulding time is very similar with organic mercury when the dosage of CUCAT-DG01 is twice as organic mercury.

    ◢ Out-standing catalytic selectivity. CUCAT-DG01 can improve the transparency of PU products significantly due to almost no catalytic activity for the reaction between isocyanates and moisture.


    Non-Foaming PU Catalyst CUCAT-DG01 / CUCAT-DG02

    The Time-Strength curve (TDI+ PPG+MOCA) as above demonstrates that CUCAT-DG01 performs very similar as organic mercury on gel point, demoulding time and demoulding strength when the dosage of CUCAT-DG01 is twice as organic mercury. Compared with CUCAT-DG01, CUCAT-DG02 shortens the post curing time by about 1 / 4 without changing the flow time.

     

    User’s Guide:

    ◢ Suggest adding in polyol component after vacuum degassing.

    ◢ To add CUCAT-DG01/DG02, the polyol component temperature should be below 80℃ at least.

    ◢ Levels of 0.05-0.5% as supplied by weight on total polyol volume.

    ◢ We don’t suggest adding in isocyanate component. To avoid gel, please do test before adding in isocyanate component to make sure the storage stability.

     

    Handling & Storage:

    CUCAT-DG01/DG02 is sensitive to moisture. Therefore, exposure to atmosphere should be avoided. Product should be stored in a cool, dry environment away from sunlight and excessive heat.

     

    Package: 25kg/200kg in HDPE drum

     

    Shelf Life: The unopened shelf life is 24 months from the date of manufacture. After shelf life, please do test to make sure the catalytic properties before use.
