Master Bond X-5TC is an aluminum oxide filled, thermally conductive elastomer-based, one component adhesive for high performance bonding and sealing. This thermally conductive adhesive bonds well in both shear and peel to similar and dissimilar surfaces including metals, woods, most plastics, ceramics, glass, rubber, paper, leather, wallboard and insulation, concrete, plastic foams and stone. Master Bond X-5TC contains a small amount (6%) of a ketone solvent which evaporates as cure proceeds. An initial set takes place in Master Bond X-5TC as soon as most of the solvent has evaporated. The strength of this initial set usually suffices to maintain the assembly and, with some adherends, will exceed the strength of the material. Bond strength increases as evaporation of the solvent progresses, reaching a maximum when all of the solvent has been removed. Master Bond X-5TC adhesive has a solids content of 94% by weight. All surfaces should be carefully cleaned and dried before application. They should be free of grease, oil, dirt and other contaminants for optimal results. Conventional cleaning methods such as solvent washing, vapor degreasing, etching, etc. are applicable. A convenient way of determining when through cleaning has been accomplished is to flow water over a vertically held coated surface. If the water runs off in a continuous film, cleaning is satisfactory. Master Bond X-5TC is an easily flowable paste. It can be thinned with ketone solvents to reduce viscosity. Cured Master Bond X-5TC adhesive features a very high thermal conductivity of 11.2 BTU•in/ft²•hr•°F (0.003 cal-cm/sec cm² °C) of 1-2 ohms/square.
