Dymax Dual-Cure 9482 is a light- and moisture-cure re-workable conformal coating, specially formulated to ensure complete cure for coating that flows underneath components on printed circuit boards. Coating in shadowed areas cures over time with ambient moisture. This conformal coating fluoresces a vivid blue when exposed to UV light (365 nm) for easy inspection of coating coverage. Dymax 9482 is engineered for coating  thicknesses up to 0.254 mm (0.010 in). Dymax Dual-Cure materials contain no nonreactive solvents. Their ability to UV cure in seconds enables  faster processing, greater output, and lower processing costs.  When cured with Dymax light-curing spot lamps, focused-beam  lamps, or flood  lamps, they deliver optimum speed and performance for conformal coating applications. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11/EC.
