Description
KE-3470-1 coating is a one-part Shin-Etsu silicone conformal coating for circuit boards and electronic components that need a flexible protective elastomer after room-temperature cure. It is a low-viscosity, 60 cPs material suited to selective spray, mass coating, and flow coating processes. For related protective products, see Chemical Concepts’ coatings and specialty chemicals category.
KE-3470-1 coating For Circuit Board Protection
Shin-Etsu describes KE-3470-1 as a fast, single-component, room-temperature curing conformal coating. It includes a UV tracer for inspection, has low odor and non-corrosive behavior, and offers unprimed adhesion to many substrates. These properties make it a strong fit for electronics shops that need visible inspection control and a coating process that can be applied without mixing a two-part system at the point of use.
KE-3470-1 coating Application Profile
The material is light yellow transparent and has a published tack-free time of 3 minutes under listed conditions. Published typical data also reports Shore A hardness of 35, tensile strength of 0.30 MPa, elongation of 40 percent, dielectric strength of 25 kV/mm, and usable temperature range of -40 C to +180 C. These values help engineers compare candidates, while final acceptance should come from board-level testing.
Process Considerations
Use this coating where a thin, flowable silicone layer is needed around leads, components, and board features. The 60 cPs viscosity supports spray and flow processes, but application settings should be tuned around board geometry, masking requirements, desired film thickness, and cure environment. Cleanliness matters because residues can interfere with adhesion or appearance.
Manufacturer And Support
Current Shin-Etsu product context is available from Shin-Etsu Silicone. Select KE-3470-1 for electronics coating work where room-temperature cure, UV inspection, and low-viscosity handling are important parts of the process. Chemical Concepts can help compare this material with other conformal coating and silicone options for production or repair needs.
