RCS

Rapid Cure Sealant

Electrolube RCS is a single component, solvent-free, low odour RTV which cures upon exposure to atmospheric

moisture. The product offers high bond strength when applied to a variety of surfaces and exhibits rapid tack-

free times. It is suitable for applications where there is the need to mechanically support components in order to

overcome vibration failures commonly experienced in the automotive industry.

 High viscosity, non-slump paste with good electrical insulation characteristics

 High bond strength and excellent adhesion to a wide variety of substrates

 Modified polymer with silyl functional group; no low molecular weight cyclosiloxanes during cure

 Remains flexible and elastic over a wide temperature range

Directions for Use Surfaces must be clean, dry and free from grease, dust and contaminants; Electrolube offer a range of cleaning products, including Ultrasolve (ULS), for such applications. Ensure that all solvents have completely evaporated prior to application. RCS is a moisture curing system. Relative humidity of 50% or above is preferred for curing.
