In terms of processing, a polyurethane spray coating is comparable to the painting process. Using a “high-pressure spray gun”, polyurethane is applied seamlessly layer by layer. The contours of the base body are retained. A major advantage of spray coating is that there are no butt joints or seams. The polyurethane coating is a continuous surface and therefore offers no open areas for wear or corrosion.<\/p>\n

The spray process also makes it possible to coat particularly large and geometrically complex components. A mold, as required for polyurethane casting, is not necessary. The coating thickness can be made thicker in areas subject to particularly high wear, depending on the conditions of use. In areas where the coating is only intended to provide protection against the weather, it can be thinner. This reduces the cost of the coating and extends the service life of the component.<\/p>\n

The main requirements for a polyurethane spray coating are:<\/strong><\/p>\n
