X5TC

Master Bond X5TC is a solvent based elastomeric system that provides very good thermal conductivity along with excellent electrical insulation. It has a paste-like consistency and is very easy to use. It is applied in a thin layer to the surfaces that are being bonded and then allowed to cure.

It bonds well to a wide variety of substrates including metals, glass, composites, ceramics as well as many rubbers and plastics. X5TC is simply applied to one of the substrates; the surfaces are mated, fixtured and the cure is then elicited by the evaporation of the solvent. Once cured, X5TC has reasonably good strength in both shear and peel modes. Since it is elastomeric, it is well suited for bonding dissimilar substrates and performs well when subjected to thermal cycling, vibration, shock and related forces. The service temperature range is from -80°F to +250°F, although it can withstand brief excursions at 350-400°F very well. It has good resistance to water and oils. This is a most interesting type of product with an especially attractive handling and curing profile. Its ability to cure readily at room temperature, without mixing and a minimal amount of solvent evaporation is certainly appealing. Most importantly, upon curing, it is an excellent thermally conductive adhesive. This product is being used in aerospace, electronic and specialty OEM applications where this handling and product property profile is desirable.
