how to do the viscosity test for traffic paint

Bituminous coatings are used on surfaces to reduce or eliminate the destructive effects of weather, chemicals and water vapour. Architectural coatings are usually applied to wood, gypsum wall board, or plaster surfaces. Products of the surface coating are essential for the preservation of all types of architectural structures, including factories, from ordinary attacks of weather, micro and macro organisms, atmospheric pollutant, etc. The fact of the matter is that many industries use several different paint testing methods in order to ensure accurate results. Testing of paint, varnishes and resins can be done in a number of different ways. In the paint and coating industries, paint testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Quality control for paint product can be achieved through conducting a number of physical and chemical tests to paint samples. It is used in the production of art, in industrial coating, as a driving aid (road surface marking), or as a barrier to prevent corrosion or water damage. Even deep or many scratches in the cup can lead to measurement uncertainties in the result, since the removed material changes the volume of the cup and thus no longer complies with the specified DIN standard.Paint can be applied to almost any kind of object. 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. Paint viscosity testers are used to measure liquids quickly and easily in order to determine their viscosity.
