Product description
Dymax SpeedMask® 9-20479-B-REV-A Blue PCB Protective Maskant cures upon exposure to light and is designed for rapid masking of electronic components and assemblies. The mask is easily removable, eliminating the concern of ionic contamination or silicone left behind by other masking methods. SpeedMask resins 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 optimum speed and performance for masking. Dymax lamps offer the ideal balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with RoHS directives 2015/863/EU.
