Product Advantages
1. Promotes ultra-uniform dispersion of potassium fluoroaluminate in aqueous stirred-tank systems, eliminating agglomerates and ensuring batch-to-batch consistency.
2. Eliminates vertical drainage (“rivulet” flow) of flux slurry during pre-brazing drying, preventing secondary crystallization and spotty coverage.
3. Zero carbonaceous residue after high-temperature brazing or oven drying; surfaces remain metallurgically clean and heat-exchanger channels stay unobstructed.
4. Induces rapid, complete wetting of aluminum substrates, producing a mirror-flat flux layer that guarantees intimate filler-metal contact.
5. Compensates for marginal degreasing or insufficient flux mobility, drastically reducing voids, skip-brazes and leakage paths.
6. Built-in micro-emulsification package dissolves rolling oils, stamping lubricants and shop soils, cutting pre-clean time while enhancing post-braze brightness.
7. Non-gumming formula—no tacky films, no baked-on skins, no cosmetic discoloration; parts emerge from the furnace bright, clean and ready for final assembly.

Usage Instructions – Aluminum Brazing Flux Additive
Add 1–2 wt % of this aluminum brazing flux additive to the total mass of potassium fluoroaluminate and water in the mixing tank. Stir until fully dissolved to obtain a uniform slurry. The solution is ready for spray or immersion application. Co-formulation with other functional additives further boosts brazing performance and appearance.
Safety & Handling
1. Keep out of reach of children.
2. Do not ingest. If swallowed, rinse mouth and drink plenty of water; seek immediate medical attention if symptoms persist.
Packaging & Storage
1. Package size: 20 kg net in sealed plastic drum.
2. Store in a cool, dry place away from direct sunlight to maximize shelf life.
