    Description
    A11-100 Additive contains alkoxy and alkyl functional groups on siloxane to improve LOI value for low smoke
    halogen free wire & cable material and improve dispersion of inorganic fillers, such as ATH/MDH etc into organic
    polymers such as resin, plastic, and rubber. It also willtransform hydrophilic inorganic powders, fillers, or
    substrates to that of hydrophobic. The alkoxy groups react similarly to that of silane coupling agents, forming a
    stable bond with the mineral filler or surface. The alkyl functionality acts as both compatilizer with organic
    polymer matrices, as well as hydrophobe to reduce water absorption. This material is also low viscosity and can be

    applied easily.


    Usage Method
    1.Pre-treatment
    This product can be applied directly to a mineral filler by atomizing onto a well mixed (preferably in a fluidized
    state for best mixing) powder. Or it can be applied by dipping, brushing, or spraying onto a surface. The additive
    can be applied neat or in a dilute solution of aliphatic hydrocarbon solvent, aromatic hydrocarbon, or anhydrous
    alcohol, generally at a level of 1% (for 1-10 micron size particles) by weight of mineral filler powders.
    Higher surface area substrates would require a higher percentage of A11-100 Additives by weight, generally
    2-3%. The treating temperature is around 70℃~120, the lower temperature the longer treating time.
    2. In-Situ Application
    This additive could be added to the extruder or mixer directly at a level of approximately 1% (for 1-10 micron
    size particles) based on the weight of the mineral filler. In some cases, it may be upwards of 2-3%. For each
    specific application, the optimum loading should be determined by testing several loadings. Because this product
    contains methanol and will generate methanol during the mixing process at elevated temperature, a vent should be
    provided and safe handling of this vent stream should be considered.
    Handling Precautions
    This product contains residual methanol and is flammable. Also when exposed to moisture, A11-100 Additive
    hydrolyses, generating methanol. Appropriate measures should be taken to prevent the accumulation of hazardous

    concentrations of methanol fumes in the working environment.


    Storage
    Stored in clear and closed steel drum, in ventilate and cool place,avoid open fire, heat insulation needed.
    When stored at or below 25°C (77°F) in the original unopened containers, this product has a usable life of at least

    12 months from the date of production.
