Master Bond has launched EP70CN, a two part, thermally stable epoxy adhesive formulated using a natural, renewable and sustainable ingredient. This epoxy system forms high physical strength bonds and can be utilized for bonding, sealing, coating and potting.

　　Master Bond EP70CN: Various Added Advantages

　　It is a low viscosity formulation with a mixed viscosity of 2,500 to 5,000 cps. With a long working life of 60 to 90 minutes and a variety of curing options, the optimal cure schedule is overnight at room temperature followed by 3-4 hours at 140°F to 170°F.

　　EP70CN bonds well to a wide variety of substrates including:

　　-Metals

　　-Ceramics

　　-Many rubbers

　　-Plastic materials

　　-Especially composites with low shrinkage upon cure

　　It features excellent wetting properties which makes it suitable for applications involving bonding and sealing fibers. EP70CN has a high volume resistivity (greater than 1014 ohm-cm) and a relatively low exotherm. This combination of properties enables it to be used in many encapsulating applications.

　　Multiple Application Areas

　　EP70CN can be used in:

　　-Aerospace,

　　-Electronic,

　　-Opto-electronic

　　-OEM applications particularly those involving composites and fibers

　　“The tensile strength is 11,000 to 12,000 psi and the tensile modulus, 300,000 to 350,000 psi. It features a glass transition temperature of 130 to 135°C”, says Rohit Ramnath, Senior Product Engineer. “The EP70CN has a very good chemical resistance profile when cured at the optimal cure schedule.”

　　In addition to specialty packaging in the form of premixed & frozen syringes and FlexiPaks®, EP70CN is available in standard packaging of ½ pint, pint, quart and gallon kits.
