RTV Silicone Adhesive is
recommended for silicone- to- silicone bonding applications.
Elkem Silicones Medical RTV Silicone Adhesives are ready for use. A bond thickness of 0.010" minimum is recommended to achieve optimum strength. Surfaces to be bonded or built-up with RTV Silicone adhesive should be pre-scrubbed thoroughly with a clean, soft sponge or soft-bristled brush in hot water-soap solution to remove possible surface contaminants. Do not use synthetic detergents or oil-based soaps, as these soaps may be absorbed and may subsequently leach out to cause a tissue reaction or reduce bond strength. Rinse copiously in hot water, follow with a thorough rinse in distilled water and dry thoroughly. Apply adhesive then mate surfaces together with light pressure. Partial cure is typically achieved in about 20 minutes. If exposed to ambient moisture, ultimate cure and optimum physical properties will be achieved after 24-120 hours of stabilization. Ultimate rate varies on the amount of material exposed to ambient moisture. Each application must be tested for optimum cure time. Adhesives may be dispersed in a variety of dry aromatic and aliphatic solvents for dipping and coating applications.
