Master Bond launches MasterSil 711Med for medical device manufacturing. It is a one part, flowable, room temperature vulcanizing (RTV) silicone which needs no mixing, and can be used for bonding, sealing, coating and form-in-place gasketing applications. This non-corrosive, translucent compound withstands many sterilization methods, including liquid sterilants, gamma radiation and EtO.
High-temperature Resistance up to 400°F
MasterSil 711Med cures very quickly upon exposure to humidity or moisture. Curing speed is influenced by the humidity level, with higher humidity in the applied areas resulting in a faster cure. Additionally, thinner sections cure more quickly than thicker ones. Tack-free time at 75°F and over 50% humidity is 2-5 minutes. Once cured, it delivers high-temperature resistance up to 400°F.
The new adhesive is electrically insulative, with a volume resistivity greater than 1014 ohm-cm at room temperature. Featuring superior flexibility, it is able to withstand thermal cycling, vibration and shock, with an elongation measuring between 300-400%. Its Shore A hardness is 25-35. It passes ISO 10993-5 testing.
MasterSil 711Med bonds well to a variety of substrates including metals, glass, ceramics, many plastics and cured silicone rubber. It is packaged in 30 cc syringes, which are equally convenient for automated and manual dispensing.
