Dymax Multi-Cure 9451 cures upon exposure to light and is designed for conformal coating of printed circuit boards. Dymax 9451 is a 100% solids, true black Multi-Cure material specially formulated with a secondary heat cure applications where shadow areas exist. It is excellent for hiding components and board features, and adheres well to a variety of materials. Dymax Multi-Cure materials contain no nonreactive solvents and cure upon exposure to light. Their ability to 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 ideal speed and performance. Dymax lamps offer the ideal balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with RoHS2 Directives 2015/863/EU and 2011/65/EU, and is UL recognized under Coatings for Use on Recognized Printed Wiring Boards – Component, File Number QMJ 42.E 140512.
