ACA Flow WR

For analyzing the coating color water retention

Process conditions in the laboratory testing
makes the value-added in real

ACA Flow WR is a modern and user-friendly analyzer for coating color water retention. Integrated touch screen and adjustable measurement pressure and time.  The modern design and clever sample holder attachment and releasement makes the measurement procedure fast and easy. The delivery package contains followings supplies: ACA Flow WR main unit, sample cylinder, testing mat with magnetics, AC Power supply, filter papers, blotter papers and a traveler case.

Measurement principle according to TAPPI T-701.

Fast and easy measurement

Substrate (base paper, nonwoven, absorbing film) is weighted, and then the sample is placed together with a filter on the lid of the device. The lid is closed. In order to simulate the process conditions, pressure (1 – 2bar) and measurement time (usually 3 – 6 s) can be selected on the touch screen.

After the controlled coating flow the substrate is measured again and g/m2 is calculated as a flow rate into the base.

Benefits of ACA Flow

  1. Possibility to measure characteristics of coating dispersions and water based solutions on flow properties
  2. Possibility to measure the influence of different base substrates on the flow characteristics
  3. Due to the dynamic flow the instrumen has an excellent correlation to real coating processes
  4. Fast and easy measurement
