FSC Flexible Silicone Conformal Coating

In Stock

FSC is a specialist conformal coating which has been formulated based on a high quality silicone resin. It is highly flexible for delicate components, while it exhibits excellent adhesion to a wide variety of substrates and operates within a wide temperature range. It’s an ideal choice for humid environments offering excellent protection from moisture. It can be sprayed, dipped or brushed and is fast drying, allowing for efficient production while it also contains a UV trace, which allows inspection of the PCB after coating to ensure complete and even coverage. FSC is widely used through the rail industry, but is suitable for a rage of high end applications. For full product details including test results please refer to the TDS below.
