Master Bond® X5G is an easy to use, solvent based elastomeric system with reliable electrical conductivity. X5G has a paste-like consistency and when used as an adhesive, it is simply applied in a thin layer to one of the substrates. The surfaces are then coupled, fixtured and the product is allowed to cure. X5G can also be applied in the same manner for coating. Curing takes place by the evaporation of the solvent.
X5G bonds well to a wide variety of substrates including metals, glass, composites, ceramics as well as many rubbers and plastics. After curing, X5G has fairly good strength in both shear and peel modes. Since it is a rubber based system, it is appropriate for bonding dissimilar substrates and holds up well when subjected to thermal cycling, vibration, shock and related forces. The service temperature range is from -80 ºF to +250 ºF, although it can withstand brief excursions at 350-400 ºF very well. It has good resistance to water and oils. Because of its handling and curing profile as well as its properties after polymerization, it is eminently serviceable as a conductive adhesive or shielding system. Its ability to cure readily at room temperature, without mixing and a minimal amount of solvent evaporation is certainly favorable. As a graphite filled material, it offers a more cost effective solution for shielding applications when compared to systems with silver or nickel. This product can be used in electronic, aerospace and specialty OEM applications where the handling and property profile mentioned previously is desirable.
