Description

Two component, toughened epoxy system for bonding, sealing, coating and potting derived from natural substances Key Features - Moderate viscosity - Superior chemical resistance - Black colored, optically opaque - NASA low outgassing Master Bond Supreme 70CN is a moderate viscosity, toughened epoxy for high performance bonding, sealing, coating and potting. The mix ratio is a forgiving 100 to 30 by weight with a user friendly working time of 60-90 minutes. It cures readily at ambient temperatures and more rapidly at elevated temperatures. An optimum curing schedule is overnight at room temperature followed by 4-5 hours at 140-170°F. Supreme 70CN does not contain any solvents or diluents and has low shrinkage upon curing. It should be noted that this epoxy has exceptional wetting properties. Supreme 70CN is an excellent adhesive and bonds well to a wide variety of substrates including metals, ceramics and many rubbers, plastic materials, and especially composites. An important feature is its toughness, which allows it to be used for bonding dissimilar substrates and to withstand thermal cycling. Other favorable attributes include good physical strength and excellent chemical resistance. It is a reliable electrical insulator, which combined with its lower exotherm, enables it to be utilized in a wide array of potting applications. The service temperature range is -100°F to +400°F. The color of Part A is black and Part B is light orange. This multi-faceted system can be considered for applications in aerospace, electronic, opto-electronic and specialty type OEM, particularly those involving composites and fibers.
