Silicone adhesive passes non-cytotoxicity standards 12 December 2023

Designed for medical device manufacturing, Masterbond’s new MasterSil 711Med silicone passes ISO 10993-5 testing. It is a one part, flowable, room temperature vulcanising (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 can withstand many sterilisation methods, including liquid sterilants, gamma radiation and EtO. MasterSil 711Med cures 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.  

Tack-free time at 75°F (23.9°C), with over 50% humidity is 2 – 5 minutes. Once cured, the silicone delivers high temperature resistance up to 400°F (204.4°C). This compound is electrically insulative, with a volume resistivity greater than 1014 ohm-cm at room temperature. The silicone features high flexibility and is able to withstand thermal cycling, vibration and shock, with an elongation measuring between 300% – 400%. Its Shore A hardness is 25 – 35. 

MasterSil 711Med bonds well to a variety of substrates including metals, glass, ceramics, many plastics and cured silicone rubber. It is packaged in 30cc syringes, which are equally convenient for automated and manual dispensing.
