Silicone Electronic Coating | MS-462H
Miller-Stephenson Silicone Electronic Coating ( MS-462H ) is a transparent, soft, flexible MIL-SPEC coating which offers excellent moisture resistance, good dielectric properties, and excellent light transmission capabilities for solar applications. It has good weatherability and resistance to U.V. light and dirt pick-up. This coating can be “solder-through” for easy repair. Contains Dow Corning 1-2577 silicone resin. This silicone resin meets the requirements of MIL-I-46058C, Type SR, IPC-CC-830B and UL 746E approval. It is also compatible with WEEE and RoHS.
Printed circuit boards (PCBs) form the foundation for electronics in automotive, consumer electronics, communications and industrial and energy applications. Yet these PCBs are often exposed to damaging environmental factors, ranging from moisture, dust and harsh chemicals to extreme thermal cycling and vibration.
Formulated from tough but flexible silicone technology, Miller-Stephenson’s MS-462H Silicone Electronic Coating 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 includinga wide range of temperatures – from -45°C to 200°C. An additional benefit of silicone conformal coating is its excellent moisture protection. MS-462H is used in cases where there were extreme temperature differences, which resulted in excessive moisture. Other conformal coatings failed within hours or days, while silicone, especially when applied thickly, has been proven to succeed. One particular application was for electronically controlled heaters developed for artic temperatures.
After cure, Miller-Stephenson’s Silicone Conformal 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.
