Ultra Light-Weld® Peelable Mask for Electronic Applications

Ultra Light-Weld® 9-318-F cures in seconds when exposed to UV/Visible light. 9-318-F peelable maskant material is designed for rapid masking of electronic components and assemblies to protect from reflow or wave soldering operations, and shield keep-out areas during conformal coating application. This maskant is highly thixtropic for manual or automated dispensing on boards or components that may be difficult to mask with other methods. It is solvent free and silicone free.

Ultra Light-Weld 9-318-F peelable mask fluoresces blue for black light inspection. Cured masks are easily removable, eliminating the concern of ionic contamination or silicone left behind by other masking methods.

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. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
