  • Features

    • Solution of silicone free, defoaming polymers with fiber
    wetting properties
    • Demonstrated equivalent air release results in
    comparative applications testing with a wide range of
    UPR resins using the recommended dosage

  • Applications

    • Wide range of UPR resins
    Includes resins thixotrped with fumed silica
    Acrylic resins

  • Dosage

    For optimum performance, mix Borchi® A-1377 into resin before the addition of other formulation components. This process
    prevents bubble formation during compounding and application processes. 0.1 – 0.5 % additive by weight (as supplied)
    based on total formulation.
