1095-NF Water-Soluble Wave Solder Flux (1 Gallon)
Water Wash Wave Solder Flux
Before no-clean fluxes became the most commonly used materials in wave soldering, water wash fluxes had an extended run as the preferred material. The advantage of water wash fluxes is that they can be formulated to be very active so that they can solder virtually any assembly without a concern for reliability, since the residue will be removed after the soldering process. The disadvantage of water wash fluxes is that assemblers must have an additional piece of equipment, the water wash system, to remove the flux residue, and must deal with the effluent.
Neutral pH fluxes can generally be left on the circuit board for extended periods of time before washing, while the "low" pH fluxes generally solder somewhat better.
1095-NF Water-Soluble Wave Solder Flux
1095-NF Water-Soluble Wave Solder Flux is a neutral pH formulation with a high level of activity for wave soldering throughhole, mixed-technology, and surface mount assemblies.
1095-NF is biodegradable and cleans readily in water to low ionic levels while leaving a surface which has a high surface insulation resistance (SIR).
1095-NF residue can remain on the assembly up to 48 hours without affecting the cosmetic appearance of the board.
Process Recommendations
- Can be applied by spray or foam
- When using with Immersion Silver and Immersion Tin, limit topside flux deposition to reduce staining
Foam Application
- Stone should be 1½–2 inches below flux surface
- Adjust air pressure to 1–3psi
- Adjust air knife pressure to 5psi to remove excess flux
- Use 16-1000 Thinner with the adjustment charts to maintain the flux density

Shelf Life
The shelf life for this product is 3 years in an unopened container stored at less than 32.2°C (90°F). Shelf life for an opened container will vary depending on storage conditions, including open time, temperature, and humidity. For longest shelf life of an opened container, replace cap to reduce alcohol evaporation and store in a cool, dry environment.
Safety Precautions
All fluxes with low flash points should be handled with caution. Store in a dry, well-ventilated area away from sparks, flames, and direct heat.
