Silicone Conformal Coating
CAS Number: 63148-62-9
Silicone conformal coating provides outstanding protection for PCBs operating in extreme temperature environments, offering a wide service range from -65°C to +200°C. Its flexible, rubber-like film resists thermal cycling fatigue and provides excellent dielectric properties even at high humidity. Preferred for aerospace, automotive under-hood, and high-temperature industrial applications.
