NuSil Technology LLC has added MED-6655, a fluorosilicone dispersion, to its line of dispersions for healthcare applications. MED-6655 is a one-part, 100 mol% fluorosilicone adhesive/sealant dispersed in tert-butyl acetate.
The dispersion comprises 60%
solids with a medium durometer. Because it is a room-temperature vulcanizing
(RTV) material, MED-6655 is ideal for spraying and dip-coating processes, as
well as sealing and bonding applications.For applications in which a standard dimethyl system may be
compromised and swell, MED-6655 can be used in its place to provide resilience
to various solvents and alcohols. In addition, the dispersion has low gas and
moisture permeability compared to a standard dimethyl system.
“MED-6655 can be used for a variety of applications because it has
less of a tendency to swell when exposed to dimethyl silicone fluids or other
solvent-based environments, including alcohols,” said Brian Reilly, product director
ofHealthcare Materials for NuSil. “It also adheres well to a variety of
The dispersion can be considered for long-term implant
applications of 30 days or more, according to the company. A variation of
MED-6655 is also available for external devices for short-term implant
applications of 29 days or less. Master Access File and biological testing will
be filed with the U.S. FDA.
