Surface protection coatings/applications

In many countries, KAEFER uses surface protection coatings to protect and preserve the structure of buildings. For example, in case of fire, these coatings ensure that the structure remains intact for longer. On surfaces such as facades, they prevent outside influences such as water or oxygen from causing corrosion, which would slowly break down the steel.

These coatings essentially consist of three layers: a layer of zinc, which insulates and protects from corrosion; an epoxy layer, which resists mechanical damage; and a top coat of silicon which stops water from getting in, is UV-resistant and provides a glossy finish. Before the coating is applied, the steel is prepared with power tools or high-pressure jets of garnet or water to remove any irregularities.

Surface protection coatings and passive fire-protection measures are used on all steel constructions in the oil and gas industries and other industries as well as in power stations, bridges, cellulose mills and fish factories. KAEFER also carries out maintenance of coatings on refineries and offshore facilities.
