The material polyurea impresses with its properties of flexibility, wear resistance, water and weather resistance, as well as very good chemical resistance. The two-component polyurea system usually reacts very quickly, which is why this material is always processed mechanically with 2K-mixing equipment. Pot times are in the range of seconds.
Polyurea is used for coating swimming pools, renovation of large roof surfaces, wear protection in gravel works and many other areas. At ACCENTFORM we use the advantages of this material for efficient coating of large-sized figures and objects. Usually we mill large-sized objects from EPS (STYROPOR). However, these objects would not be weather resistant, cannot be painted and have poor compressive strength. By coating with a polyurea hotcoat, a layer of about 2-3 mm is usually applied to the objects. This layer thickness is sufficient to give the objects an impact-resistant surface. The two-component polyurea system is heated to 80° in a machine beforehand and applied to the objects with a high discharge rate. Due to the very fast reaction, the material hardens in fractions of a second. Due to the rapid curing, the heated material has hardly any time to spread evenly over the surface of the object, because curing starts immediately. This results in basically a visible spray structure in the case of a polyurea hotcoat coating. Immediately after the application of the polyurea layer, a primer is often applied to the objects to ensure good adhesion for a subsequent surface coating. Because a polyurea coating usually offers a high level of wear protection, it would be very tedious to smooth the textured surface by sanding. The orange peel-like spray structure gives natural objects, such as animals and plants, an authentic surface. If a paint finish with a matte gloss level is used at the end, everything has been done right.
