Dual-Cure Conformal Coating

9483

High-Performance Conformal Coating with Secondary Moisture Cure


Dual-Cure 9483 is a solvent-free conformal coating that cures tack-free upon exposure to UV/Visible light and then with ambient moisture over time, on PCBs where shadow areas are present. The product also fluoresces bright blue under low-intensity UV black light (365 nm) for visual inspection of the coating coverage.

9483 is easily applied from 2-8 mils (0.002 in – 0.008 in) thick to meet the requirements of most automotive PCB designs. The material exhibits excellent corrosion and chemical resistance as well as excellent thermal cycling properties. Applications include conformal coating of rigid and flexible printed circuit boards for the automotive, general/consumer electronics, and appliance, as well as the aerospace and defense industries.

9483 is ideal for coating automotive sensors, control modules, and miscellaneous automotive components.  Recommended substrates include lead frame, PCB, flex, and ceramic.

Dymax materials are solvent-free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures.

Dual-Cure 9483 is in full compliance with the RoHS2 Directives 2015/863/EU.
