Description
Premium Grade Rosin Flux Paste No-Clean Formula for Precision SMD Electronics
This electronic soldering flux is a semi-solid, professional-grade compound developed for accurate and reliable soldering.
It is ideal for PCB repair, wire preparation, connector soldering and general electronics work.
As a result, it improves solder flow, strengthens joints and delivers consistently clean results.
Unlike ultra-thin synthetic fluxes, Xcat’s traditional rosin base leaves a fine protective film that helps guard the joint from future oxidation. Safe to leave in place — or easily removed with isopropyl alcohol if cosmetic cleaning is preferred.
Whether you are working on delicate circuit boards or heavier electrical connections, this
electronic soldering flux offers controlled performance with minimal effort.
Furthermore, it is suitable for both professionals and serious hobbyists.
Advanced Natural Resin Base
At the heart of this electronic soldering flux is WW-grade pine rosin (colophony), which is known for its excellent wetting performance.
Consequently, molten solder flows smoothly and bonds more effectively to metal surfaces.
In addition, pure beeswax is added to enhance structure and thermal stability.
This helps the flux remain consistent when heated and prevents unwanted separation.
Optimised Texture & Stability
Petroleum jelly and light mineral oil (liquid paraffin) are blended into the formula to maintain a smooth, workable texture.
As a result, the flux spreads evenly and resists drying, cracking or hardening during storage.
Moreover, a conditioning element derived from lanolin is included.
This further improves flexibility and minimises surface crusting around the container edges.
Therefore, the flux remains easy to apply over extended periods of use.
Blending
During blending, 99.9% isopropyl alcohol (IPA) is used to dissolve the resin and combine the mixture.
Once applied and heated, the IPA evaporates, leaving behind an optimised active flux layer.
Therefore, no aggressive residue is left behind on the surface.
Suitable Applications
This electronic soldering flux is suitable for copper wires, tinned pads, component legs, connectors and PCB tracks.
Furthermore, it can be used for tinning wire ends, rework tasks and general electronic repairs.
In most cases, no post-cleaning is required due to the low-residue formula.
However, for cosmetic or sensitive applications, any excess can be removed with IPA and a lint-free cloth.
