Diol hydroxy single-end silicone oil MY8866

    Diol hydroxy single-end silicone oil MY8866

    Product description:

    It is a single-end bis-hydroxy terminated silicone prepolymer with similar reactivity with polyol. It can be copolymerized with -NCO and COOH. It is mainly used for synthesizing silicon modified polyurethane resin and emulsion, and silicone modified poly. Ester resin, etc., can give the resin excellent hand feeling and improve wear resistance.

    Prevent adhesions, stains and graffiti.

    Average molecular weight 4250

    Single seal, bishydroxy structure

    Highly reactive with -NCO, -COOH

    Features:

    Greatly improve the high wear resistance of the resin or coating

    Excellent hand and slippery

    Excellent anti-stick, anti-stain and anti-graffiti

    Good resin compatibility

    Highly reactive with -NCO, -COOH

    Low surface tension for smoothing and flow

    Applications:

    Synthetic silicon PU resin and emulsion

    Modified polyester, polyurethane and urethane acrylate

    Two-component PU paint and amino paint

    Instructions:

    Silicon PU resin and emulsion: reacting with isocyanate to synthesize -NCO-terminated prepolymer, and then adding polyol chain extension reaction;

    It can also be added to the copolymerization reaction simultaneously with the polyol.

    Copolymerization with MDI and TDI at 85 ° C

    Copolymerization with IPDI is recommended at around 90 °C

    Two-component PU or amino baking varnish: adding main resin and dispersing evenly

    Storage and expiration date:

    It is stored unopened at room temperature and has a shelf life of 24 months.

    package:

    Sample packaging: 125ml brown glass bottle

    Finished packaging: 25KG plastic drum, 200KG plastic drum
