Fluoride-Free Fluxes

Flux technology has been around for a long time, and standard fluxes rely on fluoride-based chemicals for their performance. Fluoride-based fluxes do an outstanding job, but there are concerns about the health effects of fluoride fumes. Our Fluoride-Free line of products are safer to use and still produce great older joints. Okai Fluoride Free Flux is available as a standalone flux for use with wire or chip solder, or incorporated into paste solders for gold and silver-based filler metals.
 
 
Fluoride-Free Solder Paste Systems
Name Description Temperature
 MSDS TDS
NFC Fluoride-free, general-purpose system for soldering gold, silver and copper based alloys, as well as most steels. Works well with all gold and silver solders. The paste deposit is fluid and will spread when heated. Paste is nondrying and has exceptional shelf-life in excess of one year. Typical metal content is 65%. 1000 - 1600°F
NFA Fluoride-free specialty system suitable for soldering gold, silver and copper based alloys, as well as most steels. Works well with all gold and silver solders. Paste deposit is restrictive, and will not spread when heated, allowing greater precision in soldering. Care must be taken in storage of this product since it will tend to dry out if left open. Shelf life is 6 months, but can be shorter or longer depending on care during use and storage. Typical metal content is 65%. 1000 - 1600°F

NF-Flux Fluoride-free flux in a water-based paste. Can be thinned with water for desired viscosity from a thick paste to very thin, dippable solution. 1000 - 1600°F
NF-P Fluoride-free flux in dry powder form. Can be used as a dry powder or mixed with water, alcohol or a vehicle of your choice to make a slurry. 1000 - 1600°F
NF-D Fluoride-free flux in a homogenous, dispensable paste form for precise, clean application of flux only where it's needed. Ideal for precision work and repeatability. 1000 - 1600°F
