The instrument is well-suitable for the reliable quality assurance of surface pre-treatment processes as well as the development and optimization of wetting and coating procedures. Accessories for ultrafast one-click SFE measurement as well as wetting analysis at higher temperatures enhance the spectrum of the instrument.]]>
  • Quality assurance and optimization of activation processes such as plasma treatment, flame treatment, or corona treatment before coating or bonding
  • Analyzing the wettability of plastics, glass, ceramics, wood, paper, or metal
  • Analyzing surface cleanliness
  • 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
    • Contact angles of two drops dosed in parallel
    • 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
    • Remote control of ADVANCE for integration in custom-designed, complex automations

    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
