Urethane Modified Epoxy Gel

Primarily used for potting and encapsulation applications, Master Bond Super Gel 9AO is a soft, urethane modified gel-like epoxy that offers thermal conductivity and electrical insulation properties. This two part system is also employed for bonding and sealing as it adheres well to a variety of substrates including metals, glass, ceramics and many rubbers and plastics. With a low hardness of 20-30 Shore A, the product is able to encapsulated sensitive electronic components. Expensive parts are retrievable by cutting the compound with a sharp knife or razor blade. This process can be conducted without the compound shattering. This softness allows it to withstand thermal cycling as well as thermal and mechanical shock. It is serviceable from -100°F to +200°F and resists chemicals such as water, oils and fuels. The epoxy has a 2 to 1 mix ratio by weight or volume and has a low to moderate viscosity. This system offers a working life of 6-8 hours at room temperature, depending on the quantity that is mixed. It cures at room temperature with little exotherm, enabling it to be cast several inches thick.
