    TG281 Thermal conductivity silicone sealant

    TG281 Thermal conductivity silicone sealant

    Features:
    1.One component,neutral curing,non-corrosive to metal and PCB materials etc.
    2.Excellent electrical insulation and chemical stability, all-round protection to the components.
    3.Excellent thermal conductivity.
    4.Excellent moisture, ozone and corrosion resistance.
    5.Remains flexible over a temperature range of -40℃ to 180℃.
    6.The material is supplied as a paste, which cures into extremely tough elastomeric silicone rubber.

    Main applications:

    Installation:

    1.Surface preparation: Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application.Using proper materials and cleaning procedures is vital for sealant adhesion.
    2.Cleaning materials: clean, fresh solvent; clean, white cloths free of lint or other lint-free wiping materials; primer (when required).
    3.Cleaning procedures:Remove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the sealant will be adhered. Do not use detergent to clean the substrate as residue may be left on the surface. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface before it evaporates. Change the cleaning rags frequently, as they become soiled. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again.
    4.Primers: TG281 Thermal conductivity silicone sealant will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated.

    Emergent Treatment:
    Keep out of reach of children. Once it contacts skin or eye by accident, rinse the affected part with water for 15 minutes or turn to doctor for help immediately.

    Shelf Life:
    9 months from the manufacture date stored in cool & dry place below 27 ℃.

    Color:
    Clear, black, white, gray, other colours as clients’ requirement.

    Packing:
    Disposable cartridges:net 200ml, 225ml, 250ml, 280ml, 300ml; 24 pcs / box. Sausages:net 590ml, 500ml; 20 pcs / box.
