  • Process for applying a coating composition to a substrate, and the coated substrate thus obtained
    Patent number: 4517248
    Abstract: A process is provided for cleaning a substrate and providing it with a durable corrosion protecting coating by subjecting a part of the substrate to a blasting treatment and simultaneously hitting the same part of the substrate by a stream of a film forming binder. Structures in a marine environment can thus be provided with a durable coating in one combined operation of cleaning and coating. The invention also relates to the substrate thus obtained.

  • Process for applying a coating to that part of a structure in a marine environment which projects above the surface of water
    Patent number: 4340622
    Abstract: Blistering of a coating composition applied to a surface which is disposed adjacent to a body of water such as ocean salt water when the coating is applied is avoided by applying the coating composition to the surface while water is flowing over the surface.
