MasterSil 913Med is a one part acetoxy type silicone for bonding, sealing and coating for use in medical devices. It passes ISO 10993-5 cytotoxicity specifications. This fast setting system bonds well to a wide variety of substrates including metals, composites, ceramics, glass, many plastics, and rubbers, such as silicone rubbers. MasterSil 913Med can resist the most aggressive types of thermal cycling as well as mechanical and thermal shock. Typical of one part silicones, the curing mechanism is based on the humidity level. The higher the humidity, the faster the cure and thinner sections cure more quickly than thicker ones. MasterSil 913Med is a fast curing system and depending upon the application, the tack free time can range from 7-15 minutes. It withstands liquid sterilants, gamma radiation and EtO very well. Its service temperature range is -75°F to +400°F. One particularly useful product property is its ability to adhere well to silicone substrates. MasterSil 913Med can be used in a wide array of medical device applications where the acetoxy type cure is not an issue and optimum product properties are required. It should be emphasized that for biocompatibility testing, a full cure of at least 7 days is recommended.
