Aktifit VM in moisture-curing adhesives

1K PUR

Calcined product, vinyl functionalized.

Aktifit VM is applicable in 1K PUR adhesives.
The product is hydrophobic and offers very low moisture content without increase under humid climatic conditions, low rheological activity, high tensile and lap shear strength.

 

  • 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
