DOWSIL SE-9187 L Clear Conformal Coating is a transparent, single-component silicone coating designed for protecting PCBs and electronic components. It provides high dielectric insulation, resists moisture, dust, and chemical vapors, and cures quickly with an almost invisible finish. Ideal for lab-s
DOWSIL SE-9187 L is a transparent, single-component silicone-based conformal coating specifically designed for protecting electronic components and printed circuit boards (PCBs). Once applied, it forms a thin film that provides excellent dielectric insulation and protects against moisture, dust, chemical vapors, and harsh environmental conditions.
The product is available in a 330 mL bottle or aerosol format, making it particularly suitable for laboratory testing and small-scale production applications. It can be applied by brushing, spraying, or dipping. The coating cures quickly and leaves a natural, nearly invisible layer on the surface.
Transparent appearance – ideal for applications requiring aesthetics and visibility.
Single-component silicone coating.
