New Jersey, United States -- A soft, urethane modified gel-like epoxy offering thermal conductivity and electrical insulation properties is available from Master Bond.
The Super Gel 9AO is a two-part system suitable for sealing a range of materials while encapsulating sensitive electronic components.
The gel has a 2 to 1 mix ratio by weight or volume and has a low to moderate viscosity. It cures at room temperature with little exotherm, allowing it to be cast several inches thick.
Its softness allows it to withstand thermal cycling as well as thermal and mechanical shock. It is serviceable from -73°C to +93°F and resists water, oils and fuels.
