The proposed Phase II research will further examine developing a low cost, two component, self-leveling, flame resistant, high performance polysulfide modified epoxy airfield joint sealant for general use. Single component silicone is preferably used, but has poor resistance to continuous spillage of jet fuels, lubricating oils, and hydraulic fluids. Polysulfides are highly resistant to various hydrocarbon fuels and solvents. When modified and cured with an epoxy resin overall physical and mechanical properties are enhanced. The end results should show an inexpensive, higher flexibility, weatherability, and chemical resistance joint sealant.
Benefit: We anticipate this technology will be successfully proven in the resulting from Phase II efforts. The follow-up product development is dependent on refining the technology for specific applications.
