    摘要： This invention relates to a corrosion protection silicone coating system provides for easy and convenient application by conventional methods such as dipping, brushing or spraying. The coating provides a guard against environmental effects causing cathodic stress along with high physical strength and adhesion achieved with a suitable blend of reinforcing and extending fillers. The coating is an organopolysiloxane rubber coating composition containing between about 10 and 80 weight percent of a sacrificial metal filler to provide protection against environmental effects causing cathodic stress. Preferably, the coating is a one-part room temperature vulcanizing organopolysiloxane rubber coating composition to provide protection against cathodic stress. The present invention also provides for a method of coating metal surfaces to protect the metal surface from corrosion and cathodic stress. The method comprises applying to the surface a thin layer of the above one-part organopolysiloxane rubber composition and allowing the layer of the one-part organopolysiloxane rubber composition to cure at room temperature to a silicone elastomer.

    摘要： The invention provides for the protection of pipelines and other metal surfaces from corrosion. The metal surface is coated with a vulcanizable elastomeric polyorganosiloxane coating re-inforced with geo-tech fabric or any other similar nature fabric or sheeting materials. In a preferred embodiment the geo-tech re-inforced silicone provides both cathodic and corrosion protection in submersible underground and overground pipelines. The present invention also provides for a method of protecting exposed surfaces particularly metal surfaces more particularly, metal pipelines from the effects of a corrosive environment. The method comprises applying to the surface a thin layer of a vulcanizable elastomeric polyorganosiloxane rubber composition, applying geo-tech or similar fabric onto the wet surface; optionally applying a second application of the same or different vulcanizable elastomeric polyorganosiloxane rubber composition and allowing the composition to cure to a silicone elastomer.
