HACKENSACK, N.J.—Master Bond has released the Supreme 70CN, a two-part epoxy adhesive made with a natural, renewable and sustainable ingredient.
This moderate viscosity, unfilled epoxy is black in color and can be used for bonding, sealing, coating and potting. As a toughened system, it resists thermal cycling and is ideal for bonding dissimilar substrates, Master Bond said in a release.
"As part of Master Bond's sustainability drive, this product offers the advantage of lowering the carbon footprint," Senior Product Engineer Rohit Ramnath said. "At the same time, it does not compromise performance and features a high tensile strength of over 10,000 psi and a glass transition temperature of 125-130°C."
Supreme 70CN bonds well to a wide variety of substrates including metals, ceramics, many rubbers, plastic materials, and especially composites, with low shrinkage upon cure, the company said. It passes NASA low outgassing specifications, offers excellent chemical resistance, and is serviceable from -100°F to 400°F.
