Master Bond X5TC is an elastomeric system that is said to have an excellent thermal conductivity while maintaining solid electrical insulation properties. This one part, no mix adhesive/sealant has a paste-like consistency and is said to be very easy to use. It readily cures in 8-12 hours at room temperature or in 60-90 minutes at 150°F.
X5TC is said to bond 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°F to +250°F, although it can withstand brief exposure to temperatures as high as 350-400°F. It has good resistance to water and oils. This compound is available for use in ounces, ½ pints and pints containers.
