PRODUCT DESCRIPTION
SpeedMask® 9-20474-B-REV-A Blue PCB Protective Maskant with Blue Flourescent Tracer is a blue maskant that cures upon exposure to UV/Visible light for rapid masking of electronic components and assemblies. The product is easily removable, eliminating the concern of ionic contamination or silicone left behind by other methods.
The material is halogen-free, contains no nonreactive solvents, protects electronic parts from reflow or wave soldering operations. This peelable mask protects keep-out areas during conformal coating applications and is compatible with gold and copper pins. 9-20479-B-REV-A is exceptionally thixotropic for manual or automated dispensing on boards or components that may be difficult to mask with other methods.
SpeedMask 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.
SpeedMask® 9-20474-B-REV-A is in full compliance with the RoHS2 Directives 2015/863/EU.
