Product Group – Nano Additives Most certainly not invisible Scratch-proof, weather-resistant, of our customers. For example, tests The methods for analyzing the weather conductive – our innovative NANOBYK® using the crockmeter are favored by resistance, for example, of wood additives provide significant advantages the automotive sector. This test involves surfaces, are also firmly established. for surfaces. But, how can we actually pushing polishing paper across the The wooden test pieces are subjected to prove it? The answer is really simple: We coated surface. By using the grade of hundreds, sometimes even thousands use traditional, proven testing methods the paper, the weight that is applied to of hours of rapid weathering. In doing which our customers know, value and it and the number of pushing processes, so, UV light, heat and steam are applied trust. a BYK-Gardner gloss meter can measure to them. The changes to the surface and describe the changes in the gloss of of the wood are then used to prove In order, for example, to make the coating. which positive effects our nanoscale UV nanoparticles visible in our glass protection additives have. reactors, we use laser beams and As popular as the method is, it is also exploit the Tyndall effect. We also take comparatively abrasive. To find out The quadripolar electrode system in measurements using the crockmeter how a few heavy loads can change accordance with DIN EN ISO 391 is and the BYK washing- and abrasion the surface of the coating, we use the classic method for establishing the tester, and also take conductivity the abrasion tester. Depending on conductivity of a surface. This system measurements using four-pole the surface, we apply either natural helps us test materials which have been electrodes which demonstrate the bristles or synthetic fibers. Here too, optimized by our additives based on effects of our nano additives. the changes to the coated surface are carbon nanotubes (CNT technology). precisely determined by means of the By using our additives we can precisely We have a number of methods at our gloss measurement, again depending determine the effects of the coating; as fingertips for establishing the scratch- on the weight and the number of depending on the dosage, they could resistance of a coating. We select the pushing processes. be dissipative or even conductive. method according to the requirements Artificial ageing thanks to rapid weathering Conductivity measurement for our The nylon brush is less abrasive CNT-based additives 10
