Next generation REACH-compliant universal no-clean ROL0 tacky solder flux

- Industrial-grade wetting capabilities.
- Excellent ability to hold components in place.
- Clear residue does not turn brown under high-heat.
- Not-corrosive. No-clean - can be left on PCB.
- Slow burning ratio - long lasting.
- Optical UV-tracer exposing unactivated residue.
- Pleasant non-chemical scent.
- Environmentally/health friendly.

Packaged in amber syringe offering 24 months shelf life

- V3-TF is a modern no-clean universal REACH-compliant solder flux with QC-Aid™ UV-tracer and pleasant non-chemical scent mostly identified by many as "cotton candy". Makes soldering incredibly easy and fun without harming the environment or human health.
- Mighty desoldering - implements upgraded copper ions booster, visually noticeable while wicking the workspace. Instant action - quickly wets lead-free or leaded alloys aiding in delivery of perfect joints. Excellent tackiness - holds components in-place yet allows for an easy repositioning. Suitable a for multi-step assembly - get back to a project later, the flux will flow again without losing performance.
- Long lasting and economical - uses modernized fire-retardant process preventing the flux from burning away too fast. Optimal viscosity - 38-51 (Malcom @ 10 RPM/25°C (x103mPa/s)) - suitable for industrial machined placement as well as handcraft repairs and hobby use. Halide-free (<0.05%). Surface insulation resistant. No copper mirror breakthrough. Low electrochemical migration (<1 decade drop).
- Clear residue can be easily removed with hot air, foam swab and basic Solvents like Isopropanol. ROL0 classification - non-corrosive, doesn't short components, can be left on board for multiple SMT assemblies (manufacturer recommends cleaning all flux residues at all times to avoid board contamination or voltage leakage on circuits with high impedance, also non-activated residue may absorb moisture from air and subsequently cause corrosion).
- Industrial air-syringe intended for professional use with pneumatic dispensers, do not remove the piston stopper! Do not discard original nozzle cap, tighten the cap while not using the flux - flux may dry out upon extended contact with air. Does not include any dispensing components like plunger or tip which can be necessary to manually control the flow. Keep in a room temperature - do not refrigerate.


“No-clean” indicates cleaning method as defined by IPC standard and does not mean that the flux leaves no residue. No-clean rather means that the flux can be left on PCB for several consecutive SMT assemblies but also won’t cause corrosion if left indefinitely. However, cleaning can be necessary and it is desirable. No-clean fluxes are easily removed using industrial solvents in ultrasonic devices or using commercially available flux residue removers.

Storage and Handling

Tacky solder flux should be stored at room temperature (20-25°C). Refrigeration is not necessary and will not extend product shelf life. If the material has been refrigerated - consider 3-4 hours at room temperature to fully normalize. Syringes and cartridges are best stored vertically with tip pointing down. Properly stored tacky flux has up to 24-month shelf life.

Safety Notice

This product is designed for a professional consumers. The information contained herein is based on technical data that we believe to be reliable and is intended for use by persons having relevant skills at their own risk. Consumers should make their own tests to determine the suitability of each product for their particular process and take safety measures. Manufacturer/resellers assume no liability for results obtained or damages incurred through the application of the data presented.

Dispensing Kit (Plunger and Tip)

Air syringes are intended for pneumatic dispensing machines using a piston stopper instead of a plunger - reusable Dispensing Kit is a third party add-on necessary to manually controlling the flow - purchased separately.


This material is certified REACH-compliant - does not use any raw materials from the REACH restricted list of substances of high concern.
