When using a flow cup, it is particularly important to ensure that it is cleaned thoroughly after each measurement, as residues in the nozzle and cup can falsify the further results. As soon as the outflowing stream breaks for the first time, you have to stop the time and note it down.
If you now pull the glass plate horizontally from the beaker, you have to activate the stopwatch. The resulting negative pressure keeps the material in the cup. Then the glass plate is pushed over the edge of the cup to remove any excess material. An overflow channel prevents the measurement from being falsified by liquid running off the sides. Make sure that the cup is filled to the top. First you hold the nozzle underneath closed and fill in the substance to be measured. The openings of the nozzles, like the cup, are subject to a respective DIN standard. It consists of a cylindrical hollow body which in most cases ends in an exchangeable nozzle. The structure of a flow cup is standardized according to a DIN and is therefore always the same. Viscous pastes and other substances with a high viscosity are not suitable for measurement with a flow cup. However, it must be taken into account that this is only possible with less viscous liquids. * Click INFO GUIDE for testing descriptions and results Excellent latex and paint stabilityįormulations using ACRONAL Xpress 4347 perform exceptionally in heat and freeze thaw stability tests compared to commercially available traffic marking paint.Paint viscosity testers are used to measure liquids quickly and easily in order to determine their viscosity. Example of traffic paint failing ASTM D711 no-pick-up test. Formulation with ACRONAL Xpress 4347 showing no paint pick-up on wheel. No-pick-up time is observed after four minutes and 30 seconds, which exceeds industry standard of 10 minutes (ASTM D711*). Traffic paints formulated with ACRONAL Xpress 4347 exhibit exceptionally fast drying. Performance Exceptionally fast drying time
