Description
KE-1871 coating is a one-part Shin-Etsu heat-cure silicone conformal coating for circuit boards and electronic components that need a durable, flexible protective elastomer. It is designed for selective spray coating, mass coating, and flow coating, giving production teams several ways to apply a controlled protective layer.

KE-1871 coating For Heat-Cure Electronics Work
Shin-Etsu lists KE-1871 as a fast, single-component, heat-curing conformal coating with high heat resistance and unprimed adhesion to many substrates. The one-part format can reduce shop-floor mixing steps while still giving engineers the benefits of an addition-cure silicone coating. It is a practical candidate for boards, modules, and electronic components where the assembly can tolerate the specified heat-cure schedule.
KE-1871 coating Typical Properties
Published data reports a light yellow translucent material with 900 cPs viscosity, 24-hour working time, Shore A hardness of 27, tensile strength of 2.20 MPa, and elongation of 180 percent. Shin-Etsu also lists a cure condition of 30 minutes at 120 C and a usable temperature range of -40 C to +180 C. Treat these values as comparison data and confirm performance on the actual board materials, coatings, and process conditions.
Application And Handling
Use KE-1871 where heat cure is acceptable and where the coating needs to remain flexible after cure. The 900 cPs viscosity gives more body than very low-viscosity conformal coatings, which can help in applications requiring controlled flow. Board cleanliness, masking, film thickness, cure temperature, and cure time should all be controlled during process qualification. Qualification should also include any cleaning chemistry, solder mask, component packages, and rework steps that the board will see after coating.
