When ultimate wear resistance is required, a polyurethane coating can be cast or sprayed on the surface of the product. This will protect the product from abrasion (sand, soil, gravel and other particles), moisture, water, oil, chemicals and corrosion.
A spray polyurethane coating is suitable for most substrates and follows the shape of the product. It can therefore be applied to almost any shape imaginable as well as to large surfaces. Spraying is a quick way of getting a product covered and ready to use. Pipe interiors can also be coated using equipment developed by SMH-Uretan. Spray application creates dense, seamless surfaces, keeping the thickness at only a few millimetres. Coating can be carried out on SMH-Uretan’s premises or the customer’s premises, using mobile spraying equipment.
Casting should be chosen when higher hardness is required. In this case, we use in-mould coating, which also enables the creation of patterns on the surface. The hardness of the material can vary greatly. Cast polyurethane coatings are used, for example, on the inner surfaces of shaft covers when these are exposed to water and temperature fluctuations.
