Two Component, Addition Cured Medical Grade Silicone for Bonding and Sealing

Master Bond® MasterSil 153Med is a two component silicone compound with a paste consistency for high performance bonding and sealing. Most significantly it can be used for medical device applications as it meets USP Class VI testing and ISO 10993-5 for cytotoxicity. MasterSil 153Med is an addition cured system and does not require exposure to air for cross-linking. It has a convenient one to one mix ratio by weight, and will not outgas while curing. It is 100% solids and contains no solvents. MasterSil 153Med exhibits typical silicone flexibility and high temperature resistance. MasterSil 153Med has an exceptionally long working life and very low exotherm. It bonds well to a wide variety of substrates including most metals, many plastics, glass and ceramic. Most importantly, it will bond well to cured silicone rubber. It has superb electrical insulation properties. Its remarkable flexibility allows it to withstand severe thermal cycling and resist vibration and shock. It has a self priming feature that enhances the bonding properties of the system. Also, it is very water resistant. MasterSil 153Med is translucent and is serviceable over the broad temperature range of -65ºF to +400ºF. It is widely used in medical device applications where high flexibility and splendid temperature resistance are required.
