Master Bond X-5 is specially formulated, synthetic elastomer-based, one component adhesive for high performance bonding and sealing. This synthetic elastomer based 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-5 contains 30% solids and has a carefully designed solvent blend which evaporates as the cure proceeds. An initial set takes place in Master Bond X-5 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-5 adhesive has a solids content of 30% by weight as supplied. 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-5 is a readily flowable liquid. It can be further thinned with ketone solvents, etc., to reduce viscosity. Cured Master Bond X-5 adhesive retains its high strength even after exposure to or immersion in water and many other chemicals including fuels, oils, etc. It is an electrical insulator. Master Bond X-5 also features superior electrical insulation properties. The adhesive meets MMM-A-1617 Type III specifications.
