Designed for rapid masking of electronic components and assemblies, Ultra-Light Weld 9-20479-B provides protection from reflow or wave soldering processes and shields no-go areas during conformal coating application. This easily dispensed mask enables accurate placement and cures in seconds to maximize production throughput with the highest levels of quality.
DYMAX 9-20479-B is a blue, peelable masking material which cures in seconds when exposed to UV/visible light. It is extremely thixotropic and is ideal for manual or automated dispensing on printed circuit boards or components that may be difficult to mask with other methods.
The material composition features no solvents, silicones or VOCs, whilst its performance ensures that the cured masks withstand wave solder and reflow temperatures and are easily removed, eliminating the concern of ionic contamination or silicone left behind by other masking methods.
