Master Bond X5TC is an elastomeric system that has a thermal conductivity of 10 to 12 BTU in/ft•2 hr•°F (1.44 to 1.73 W/m•K) while maintaining solid electrical insulation properties. This one part, no mix adhesive/sealant has a paste-like consistency and is easy to use. It readily cures in 8 to 12 hours at room temperature or in 60 to 90 minutes at 150° F.
X5TC bonds well to many substrates including metals, glass, composites, ceramics, rubbers and plastics. Since it is elastomeric, this compound is suitable for bonding dissimilar substrates and performs well when subjected to thermal cycling, vibration and shock.
X5TC can be used in aerospace, electronic and specialty OEM applications. The service temperature range of this product is from -80° to 250° F, although it can withstand brief exposure to temperatures as high as 350 to 400° F. It has good resistance to water and oils. This compound is available for use in ounces, ½ pints and pints containers.
