Silicone Conformal Coating

Miller-Stephenson’s Silicone Conformal Coating provides excellent moisture and fungal resistance with good dielectric properties in a soft and flexible “solder-through” coating. Silicone conformal coatings excel at high temperature exposure ( >120C) and high vibration applications. Our formulation utilizes Dow Corning 1-2577 Silicone Resin, which conforms to MIL-I-46058, Type SR, IPC-CC-830B, and UL Standard 746E. Includes an ultraviolet (UV) indicator and the formulation is 100% non-flammable.

Formulated from tough but flexible silicone technology, Miller-Stephenson’s Silicone conformal coatings promote extended service life and enhanced reliability for your PCB components and assemblies. Our industry-leading solutions have delivered proven protection for decades against moisture, service environment and a variety of harsh operating conditions including a wide range of temperatures – from -45°C to 200°C. After cure, Miller-Stephenson’s silicone coatings deliver dependable, long-lasting protection. Their natural elasticity also helps minimize mechanical or thermal stress on delicate component leads. Additional select grades deliver tougher, more abrasion resistant coatings ideally suited for electronic printed wiring board applications.
