800-550 is a UV curable silicone flowable conformal coating, pottant, or sealant.

800-550 is a non-corrosive, single component silicone that will cure to a solid elastomer in seconds upon exposure to ultraviolet (UV) light. 800-550 has a secondary, neutral alkoxy moisture cure for enhanced adhesion and shadow cure.

With a viscosity of 5,500 cPs, 800-550 flows readily to surround the complex geometry of modern circuitry design. 800-550 contains a standard UV tracer for quality control.

The next generation of Novagard UV/Dual Cure silicones cures tack free in a fraction of the time needed for traditional conformal coatings. After the initial UV cure, the secondary, ambient cure enhances adhesion and ensures no unreacted coating remains in shadow areas. Providing a faster, more reliable cure, our 800 series of products is an attractive alternative to solvent-based solutions.
