Cobar selective soldering flux 95-SEL

A low-VOC selective flux designed for use in industrial applications, 95-SEL has an anti-solderballing formulation as well as high activation to increase solder performance to optimum levels. However, because it features a water content of 40%, this flux is not the best choice for high-tech/high-reliability electronics.
