Handy Flo 800 Solder Pastes
Handy Flo 800 is a flux/binder system for solder alloys. These low temperature flux-binder systems are intended for soldering applications under 450°C / 840°F. Suitable heating methods include torch, induction, resistance, infrared, hot plate or oven, and clean-up is easily accomplished with a hot water rinse. Typical formulations are up to 85% metal by weight.
Brazing and soldering pastes incorporate filler metal, flux, and a binder in a one-step application process. Because pastes are readily applied, they lend themselves well to both manual and automated production operations. We offer several flux/binder systems for specific temperature ranges and brazing processes.
