    IOTA 1647V75 Organo Functional

    Description :

    IOTA LD 1647V75 is a low-viscosity, linear α,ω- hydroxypropyl polysiloxane fluid.

    Examples of applications

    IOTA 1647V75 carbinol silicone may be used as an intermediate in the manufacture of silicone/polyester or silicone/polyurethane copolymers.

    It is used in place of, or in addition to, the "diol" part of these polymers.

    Having an α,ω-hydroxyalkyl functionality, the silicone is permanently co-polymerised into the chains or cross-linked matrices of the polyester or polyurethane.

    This carbinol silicone co-polymer may also be used as an additive in polyester- and polyurethane-based paint to improve properties.

    IOTA 1647V75 imparts the typical properties of silicones to polyesters and polyurethanes:

    1. Non-stick properties

    2. Abrasion resistance

    3. Scratch resistance

    4. Lubrication

    5. Water repellency

    6. Weatherability

    7. Plasticity

    8. Low temperature flexibility

    9. High temperature stability

    10. Electric insulation


    1. Appearance:  clear liquid

    2. Color : Colorless to yellowish brown or red

    3. Specific gravity (at 25 °C, approx.) : 0.97

    4. Viscosity (at 25 °C, mm2/s, approx.) : 75

    5. OH content (mg KOH/g, approx.) : 47

    6. Refractive index (at 25 °C, approx.) : 1.409

    7. Flash point (closed cup, °C):  > 169


    IOTA 1647V75 is delivered in 200 kg drums and in 1000 kg containers.
