Neutral curing silicone formulated for medical devices
Designed for high performance bonding, sealing and coating applications for medical devices, MasterSil 912Med is a room temperature vulcanising silicone system. This system meets both USP biocompatibility and ISO cytotoxicity standards and resists a variety of sterilisation techniques such as gamma radiation, EtO and some types of liquid sterilants.
This one part system has a paste viscosity and non-corrosive cure with a tack-free time of 15-30 minutes at room temperature. Similar to other single component silicones, MasterSil 912Med’s cures depended upon the humidity level. The higher the humidity, the faster the cure and thinner sections cure more quickly than thicker ones. It is translucent in colour and is serviceable over the wide temperature range from -59.4 to +204.4°C (-75 to +400°F).
MasterSil 912Med has a tensile strength of 700-1,100psi and offers superior adhesion to many materials, including metals, composites, ceramics, glass, rubbers, plastics and other silicone substrates. Featuring an elongation of 250-350%, this flexible system can withstand highly rigorous thermal cycling as well as thermal and mechanical shock. It is a reliable electrical insulator with a volume resistivity greater than 1015Ω-cm.
MasterSil 912Med is available in 80g tubes and has a shelf life of 6 months.
