Silicone Conformal Coatings provide flexible protection to printed circuit boards and are especially useful in applications where wide temperature ranges are expected for electronic assemblies.  Silicone conformal coatings exhibit high elongation and low modulus at low temperatures and remain stable at high temperatures.  They are especially favored in many Automotive, Aerospace, and Outdoor Appliance/Equipment applications.  They are normally one-part systems with or without a solvent carrier, and they cure by heat or moisture (atmospheric).  Nearly all systems are MIL-I-46058C and IPC CC-830B specified and most have some level of UL acceptance.
