Abstract
To overcome the capability gaps of current joint sealants, HMC will rely in part on our previous internal engineering analysis and experience to explore commercially available sealants that incorporate novel additives to improve joint sealant performance and longevity. HMC has experience and expertise in developing sealants for high operating temperature applications. In 2004, HMC performed preliminary research and testing to develop high temperature joint sealants. HMC engineers developed a novel method for compounding concrete joint sealants that provided high heat resistance through the formation of a surface thermal passivation layer when exposed to high temperature gas and flame. These formulations endured repeated exposures of 1400oF while maintaining structural and mechanical sealing capabilities. Excellent sealant flexibility and adhesive properties remained intact with no subsurface sealant degradation, melting or burning. For this SBIR effort, HMCs goal is to present improvements to those previous formulations to provide the USAF with novel and cost effective concrete sealant that can withstand the high temperature and jetblast velocities of VTOL aircraft. BENEFIT: The Joint Sealant for High Operating Temperatures (JSHOT) proposed herein will have the thermophysical properties necessary to provide USAF with the following performance: Withstand repeated exposures of 1700oF Maintain long life structural and mechanical viability Decrease FOD Remain Weather/UV Resistant Easy to apply Low viscosity and self leveling Resiliency to high velocity exhaust High chemical resistance Cost effective
