Master Bond Polymer Adhesive EP41S Medical is a two component low viscosity epoxy resin system for high performance bonding, sealing, coating, as well as small encapsulations, pottings and castings. It is formulated to cure readily at room temperature or more quickly at elevated temperatures. One notable property is its very fast curing at room temperature.  It has a 5 to 1 mix ratio by weight and contains no solvents or diluents.  Master Bond Polymer System EP41S Medical produces high strength rigid bonds, which are remarkably resistant to chemicals including water, oil, many organic solvents, as well as cold sterilants, ETO and gamma radiation.  It has a wide service temperature range of -60°F to + 250°F.  It bonds well to a wide variety of substrates including metals, glass, ceramics, wood and many plastics.  EP41S Medical has exceptionally low linear shrinkage upon cure.  The cured compound is an outstanding electrical insulator.  EP41S Medical’s low viscosity makes it excellent for small encapsulations, pottings and castings.  In addition, EP41S Medical meets USP Class VI specifications, making it well suited for a variety of uses in medical devices as an adhesive, sealant and coating.  EP41S Medical also meets FDA requirements listed above for food compatibility.
