Alcoholic hydroxyl double-terminated silicone oil MY8865H

    Alcoholic hydroxyl double-terminated silicone oil MY8865H

    Product description:

    It is a silicone oligomer with bishydroxy functional group, which has similar reactivity with polyol, copolymerization with -NCO and COOH, and is mainly used for synthesizing silicon modified polyurethane resin and emulsion, silicone modified polyester resin, etc. It can give the resin excellent hand feeling, improve wear resistance, prevent adhesion, antifouling and anti-graffiti.

    Technical indicators:

    Parameter                                             value

    Appearance :               Colorless to slightly yellow transparent liquid

    Hydroxyl content % :                              0.8

    Average molecular weight:                      4000

    Viscosity 25°C cst :                             1500-2500

    Solid content % :                                 ≥98.00

    Product 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:

    Similar to polyester diol and polyether diol

    Synthetic silicone modified polyurethane resin and emulsion

    Two-component PU paint and amino paint

    Instructions:

    Polyurethane resin and emulsion synthesis: added simultaneously with the polyol monomer or added in the latter stage of the synthesis;

    Copolymerization with MDI and TDI at 85 ° C

    Copolymerization with IPDI is recommended at around 110 °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
