Product Group – Surface Additives Surfaces are the right way to go As a specialist in interfaces, we can or pre-existing coatings. Combining fall back on profound expertise in both values provides a precise image the surface behavior of a wealth of of the behavior of the liquid that has different materials. Our key aids here been optimized by our additive on the are our measuring technology and the specific substrate. associated analyses. However, we implement dynamic With their help we can characterize procedures to analyze the surface the behavior of various surfaces and behavior of materials for our customers make statements about the wetting from the printing and paper industry properties and the appropriate adhesion and the wood-processing industry. With application to use. Simultaneously, the aid of a bubble pressure tensiometer we can discover how to avoid we can simulate the behavior of the leveling problems and cratering. This liquid under high pressure and at great represents the basis on which we speeds. discuss recommendations for suitable additives that can be applied and their The MicroSpy provides even more appropriate dosage. detailed results. The confocal Dynamic measurement with the bubble pressure microscope allows a three-dimensional procedure The starting point for our analyses representation of incredibly small is static measurements. We use a surfaces of maximum 37 mm². This tensiometer to investigate the surface analysis gives us very exact images of tension of liquids in which our additives the surface topography, which we then are to be effective. We implement evaluate using a separate procedure. the contact angle method to analyze We are able to precisely analyze the solid surfaces, like steel, wood, plastic topography of the surface and use this on which to base concrete statements concerning the roughness, waviness and the wetting and adhesion behavior of liquids. At our customer´s request, we can also implement these procedures to detect other effects, e.g. cratering. MicroSpy provides us with an image of the surface Contact angle method for solid surfaces topography 13
