The instrument provides rapid results for the wettability of a surface, for example for checking the quality of cleaned, pretreated, or coated samples.]]>
  • Quality assurance of activation processes such as plasma treatment, flame treatment, or corona treatment
  • Checking wettability of plastics, glass, ceramics, wood, paper, or metal
  • Testing the effectiveness of hydrophobic coatings and other coatings
  • Wetting analysis at controlled temperature

    • MEASURING METHODS

    • Contact angle of a drop on a solid surface
    • Contact angle using a gas bubble beneath a solid surface in a liquid
    • Surface free energy of a solid using contact angle data
    • Surface tension using the curvature of a perfectly symmetrical drop on a circular sample pedestal
    • Roll-off behavior and advancing/receding contact angle of a drop on a tilted surface
    • Carrying out a measurement up to 20 consecutive times and displaying the results together

    MEASURING RESULTS

    • Static contact angle
    • Advancing and receding contact angle
    • Contact angle using a bubble in a liquid
    • Surface free energy (SFE) according to the following models: Owens-Wendt-Rabel-Kaelble (OWRK), Fowkes, Wu, Zisman, Equation of State
    • Temperature
