TQC has expanded its line of test equipment for the paint and coatings industry with a brand new wet scrub washability tester. Surfaces that are likely to be cleaned often such as table/desk tops, white goods, furniture, floors and walls, automotive interiors etc. need to be tested on their resistance against mechanical cleaning with or without use of detergents and check for parameters such as gloss retention, scratches, discolouration and other signs of mechanical wear.
The TQC scrub tester is a very flexible machine that can be used to test various materials such as hiding power test charts, scrub panels, metal-, plastic-, or wood panels or parts, etc.. For popular ISO and ASTM standards the settings are pre-set in the machine but all parameters are fully flexible. Cycle speed (1 to 60 str/min), stroke length (2 to 300 mm), pump volume (0 to 3 ml/min), number of cycles or test duration can all be set digitally by the operator. The machine has two separate dosing pumps which allows simultaneous testing of two different media. The volume of the pumps can be set individually.
An integrated marker makes it possible to set marks individually per channel to remind the operator when certain damage on the surface has occurred. A flexible acoustic signal is available to mark a (user preset) number of cycles. To meet the requirements of different standards and tests a wide range of tools such as wild boar brushes, nylon brush, sponges, abrasive pad etc. are available.
