Two Component, Room Temperature Curing Epoxy Adhesive for Bonding, Sealing and Coating Featuring High Temperature Resistance, Outstanding Toughness and Excellent Physical Properties.
Master Bond EP33-3 is a two part, room temperature curing epoxy system used for bonding, sealing and coating featuring high temperature resistance and superb toughness along with very fine physical properties. It has a 100 to 70 mix ratio by weight and a very convenient one to one ratio by volume. This system cures readily at room temperature or more rapidly at elevated temperatures. To optimize its properties, the recommended cure schedule is overnight at room temperature followed by a post cure at 150-200°F for 2-3 hours. Once cured EP33-3 has an exceptionally high temperature resistance, serviceable up to 450°F. One particularly desirable feature is its toughness which translates into a superior ability to withstand thermal cycling and shock. It resists a wide range of chemicals including water, oils, fuels and many acids and bases. This moderate viscosity system bonds well to a wide variety of substrates including metal, composites, glass, ceramics and many rubbers and plastics. It is a top-notch electrical insulator. EP33-3 is 100% reactive and does not contain any diluents or solvents. The color of Part A is gray, Part B is tan. It is widely used in aerospace, electronic, electrical and specialty OEM type applications.
