    Hydroxyl Silicone Oil


    Hydroxyl group dead-ended polysiloxane.

    Polymer hydroxyl silicone oil is the organosilicon material polymerized by siloxane monomer with hydroxyl

    groups at both ends of molecules.

    Structure: HO-Si(CH3)2 O(Si(CH3)2 O)nSi(CH3)2-OH

    Chemical name is a,w-dihydroxylpolydimethylsiloxane. Conventionally the hydroxyl silicone oil with viscosity

    above 250 mPa.S is called 107silicone sealant. Apart from general functions of hydroxyl silicone oil, this

    product possesses the reactivity of hydroxyl group that can be made into some new material or crosslinked

    as elastomer(or film body).

    This product is colorless transparent liquid with excellent electrical insulation, high and low temperature

    resistance, high flash point, low freezing point, long-term adaption to temperature from -50ºC to 250ºC,

    low viscosity-temperature coefficient, high compression rate, low surface tension, good water repellent

    and moisture resistance, chemical inertness, physical inertness.

    Used as main raw material in RTV mold silicone rubber, defoamer and silicone glass cement.
    1. Used as insulating, moisture resistant, anti-shock and heat resistant perfusion sealing material in radio,

    electronic equipment, semiconductor and other electronic components and assemblies.
    2. Used as rubber roller material in automobile and machinery industry.
    3. Used as rubber roller material in textile, plastic and printing industry.
    4. Caulking sealing material in construction industry.
    5. It has excellent mold release performance, particularly suitable for the manufacture of precision mold and

    impression materials.



    No mixing with acid-base materials, alkoxy silane or high temperature water vapor, otherwise there is the

    tendency of curing and viscosity changes.
