Aktifit AM in moisture-curing adhesives

STP-E / STP-U

Calcined product, amino functionalized.

Aktifit AM enables lower concentrations of amino silane in the formula.

 

  • excellent strength of properties, up to 2-fold or 3-fold calcium carbonate (tensile strength and lap shear strength), mostly without reducing the ultimate elongation
  • good water resistance and chemical resistance
