Field of Application – Anti-corrosion Systems The art of simulation If you want to know whether or not the influence of our additives with regard protective coating on steel structures to the cathodic delamination (cathodic really works, you have to subject it to disbondment, CD). Here our adhesion wind and weather. Reliable statements promoter in the coatings can help to concerning fire protection are also slow down the inevitable delamination only possible if the coating has been process. subjected to fire at least once. Alongside corrosion tests, we test how In the laboratory we therefore aim to our additives influence mechanical simulate these conditions in accordance properties, as protective coatings and Salt spray test with precise stipulations. The respective marine paints are frequently subjected standards are used as a basis for to considerable mechanical loads. The this. For example, the EN ISO 12944 more flexible the coatings, the lower corrosiveness categories specify which the danger that mechanical loads will loads steel coatings must be able to damage them. The Erichsen tester in withstand. accordance with EN ISO 1520 is used to test the elasticity of a coating. More The testing methods and equipment dynamic test procedures would be that we use to measure the effects of the direct or indirect ball drop test in our additives on protective coatings and accordance with EN ISO 6272. marine paints also work in accordance Sheets in the salt spray test with precise guidelines. For example, Our additives improve the workability the condensed water test in accordance and performance of intumescent fire with EN ISO 6270-2 and the neutral salt protection coatings. To discover which spray test as per EN ISO 9227. effects our additives could invoke in an emergency, we subject the steel We apply these methods not only in sections which have been coated order to test our own new developments with test formulations to very high in the area of wetting and dispersing temperatures. For this purpose, we agents, rheology and surface additives, simulate an appropriate fire load in a nanoadditives as well as adhesion so-called “muffle oven”. promoters; we also use them to help Condensed water test our customers. They can use our test results as a basis for selecting suitable BYK additives before they really have to knuckle down to testing their own formulations using the respective testing methods. A very special test procedure where we, for example, simulate the cathodic protective coating for pipelines, provides us with information about the Muffle oven 43
