From flights within the Earth’s atmosphere to explorations into the final frontier, ensuring the operational integrity of complex systems is critical to every mission. Designers and engineers need adhesives and sealants that can optimize safety, component life span, and efficiency under extreme conditions, while still allowing the kind of innovative engineering to meet new challenges and goals.
With Novagard’s electronics grade silicones, and our knowledgeable experts in the lab, there is no barrier to what you can accomplish. Our silicones are UV resistant and naturally stable under a wide range of temperatures and moisture conditions. We can further tailor solutions to optimize performance qualities like thermal management, EMI shielding, and durability, customizing a solution to meet the most stringent performance requirements to ensure mission success.

800-610 is a low viscosity, pourable encapsulant. Its extremely low viscosity ensures the material flows easily around components for thorough wet-out. This is a UV cure with no secondary moisture cure, offering very low adhesion.
800-520FC is a UV-curable, silicone conformal coating, pottant, or sealant. This version of our original 800-520 coating utilizes Fast Cure technology to begin moisture cure of shadow areas in as little as 30 minutes, and provides a harder, more durable surface than our standard 800-520.
800-505FC is a UV-curable, silicone conformal coating, pottant, or sealant. It has a secondary, neutral alkoxy moisture cure for enhanced adhesion and shadow cure. Utilizing our Fast Cure technology, this secondary moisture cure begins in as little as 30 minutes and can develop full adhesion in hours.
