Product Description: Master Bond EP21FL is a lower viscosity, two component, flexibilized epoxy resin system for high performance bonding, coating, sealing and encapsulating. It is formulated to cure at room temperature or more rapidly at elevated temperatures, with a four to one mix ratio by weight. This compound is 100% reactive and does not contain any solvents or volatiles. It bonds well to a variety of substrates, including metals, glass, ceramics and many plastics. Since it is a toughened system, it is ideal for bonding dissimilar substrates with differing coefficients of expansion. EP21FL is effective for bonding surfaces subjected to rigorous thermal cycling as well as thermal and mechanical shocks. EP21FL is a wonderful potting compound, particularly for larger encapsulations. Its excellent electrical insulation properties are especially significant. EP21FL features an exceptionally long working life, along with a low exotherm while curing. It is resistant to chemicals including water, oils, salts, etc., over the wide temperature range of -100°F to +250°F. Part A is transparent and the color of Part B is amber-clear. Master Bond EP21FL is widely used in electronic, electrical, optical and aerospace applications, among others.Product Advantages: - Convenient mixing: four to one ratio by weight
