Along the same lines as the previous question, can the silicone foul release coatings be applied over an existing system?
A Yes, as long as all contaminants and loose paint are removed leaving a solid, intact surface that will accept epoxy paint. Back to Top Q What surface preparation is required? A For ferrous and non-ferrous metals, SSPC-SP6 Commercial Blast Cleaning, or SSPC-SP12 Water-jetting to WJ-2. A bare substrate is a preferred with a profile depth of 3 mils. For concrete, SSPC-SP13 Surface Preparation of Concrete. Back to Top Q Can silicones become brittle with age and or heat? A FHSMs silicone is similar to that used in the highest-grade outdoor caulking. That does not become brittle with age, heat or UV exposure, and is guaranteed by the manufacturer for 30 years. Excellent resistance to aging and the environment is one of the unique properties of silicones compared to other polymers. It is because silicones are based on silicon and oxygen polymer chains rather than carbon based polymer chains that these outstanding performance properties can be achieved.
