Spot-on is a temporary solder resistance designed to be used on printed circuit boards prior to soldering and will withstand fluxing and wave soldering operations. This easily peelable and non-staining material can be applied undiluted as supplied, but if desired may also be thinned with up to 50% of water for brush application. The material dries in 40 minutes at 80 Celcius Degrees or 2 hours at room temperature.
