ABSTRACT:
A fluoroelastomer-hollow glass microsphere coating has been found to provide new and unexpected corrosion resistance to metal surfaces for protection against severely corrosive environments. The coating comprises a fluorocarbon elastomer and 3-50% by volume of hollow glass microspheres or microballoons having a size in the range of about 2-300 microns, preferably 20-200 microns. The hollow glass microspheres or microballoons substantially increases the corrosion resistance of a fluoroelastomeric liquid composition, yielding new and unexpected thermal and chemical resistance, particularly when the coating composition is applied in two or more layers.
