ACAV AX-100

Next generation ACAV ultra-high shear viscometer for coating optimization

Next Generation ACAV Viscometer
ACAV AX100

For Optimum Coater Runnability

  • – Capillary viscometer for FAST EVALUATION of the coating rheology
  • – Shear rates up to > 1 000 000 1/s
  • – For product development and quality control in HIGH SPEED COATINGS

Benefits of ACAV AX100

Real coating conditions

Coating colors are rheologically complex materials. Their viscosity is strongly dependent on shear rate. Modern highspeed coaters generate shear rates > 1 000 000 1/s

ACAV AX 100 measures viscosity at shear rates > 1 000 000 1/s whereas low shear rheograms that are commonly used in the industry demonstrate only low shear viscosity portion and can be extremely misleading when it comes to the prediction of coating performance or runnability on high speed coaters.

Speed up coating development

Unique and tailored measurement head design provides excellent contact with the web and eliminates the leakage air, dust and other disturbances.

Generated stable air flow leads to very high correlation (> 0,95 R2) between ACA Permi and any lab standard (Gurley, Bendtsen, Coresta, delta P…)

Roll to roll data and color maps with high statistical confidence to identify uniform and non-uniform rolls.
