The MED-6655 fluorosilicone dispersion from NuSil (Carpinteria, CA) is comprised of 60% solids with a medium durometer. Because it is a room-temperature vulcanizing (RTV) material, it is suitable for spraying and dip-coating processes, as well as sealing and bonding applications. It may be used in place of a standard dimethyl system to provide resilience to various solvents and alcohols. It also features low gas and moisture permeability compared to a standard dimethyl system. It adheres to a variety of substrates and may be considered for long-term implant applications of 30 days or more. A variation of MED-6655 is also available for external devices for short-term implant applications of 29 days or less.
