TSC Blackband Flux Advances Zinc and Cast Iron Welding

In the world of metal joining, professionals have long faced challenges finding reliable, high-performance fluxes that deliver consistent results. Subpar welding outcomes often lead to project delays and cost overruns. The introduction of TSC BlackBand flux represents a significant advancement, offering both exceptional performance and operational efficiency.

Superior Performance in Water-Based Flux Technology

TSC BlackBand stands out as a high-performance water-based flux featuring a proprietary formulation combining zinc chloride with active salts. This innovative composition provides exceptional fluxing action at soft soldering temperatures for both ferrous and non-ferrous metal alloys.

Engineered to meet modern industrial demands, BlackBand delivers reliable performance across multiple applications—whether joining copper and brass components, working with low-carbon steel automotive bodies, or applying solder coatings to cast iron structures.

Versatile Applications Across Industries

With an established history in industrial soldering, BlackBand has proven particularly effective in copper-brass heat exchanger manufacturing when used with gas torches. Its consistent performance has made it the preferred choice for professionals tackling complex joining tasks.

Comprehensive Product Range

Available in multiple container sizes, BlackBand accommodates diverse operational requirements:

• 125ml (Internal SKU: LF-261-029)
• 250ml (Internal SKU: LF-261-034)
• 1L (Internal SKU: LF-261-025)
• 5L (Internal SKU: LF-261-026)
• 10L (Internal SKU: LF-261-021)

This range supports everything from precision soldering tasks to large-scale production environments.

Key Technical Advantages

BlackBand's formulation provides several distinct benefits:

• High Activity Fluxing: Effectively solders copper, brass, low-carbon steel and cast iron while ensuring joint integrity.
• Water-Soluble Residues: Post-soldering cleanup requires only water, eliminating the need for specialized cleaning agents.
• Broad Alloy Compatibility: Works seamlessly with both lead-tin and lead-free solder alloys.

Overcoming Cast Iron Soldering Challenges

Soldering cast iron presents unique difficulties due to its high carbon content and thermal properties. The material's tendency toward crack formation and porosity during joining operations requires specialized solutions.

BlackBand addresses these challenges through enhanced wetting characteristics and improved flow properties, enabling uniform solder distribution across cast iron surfaces. The flux actively removes surface oxides and contaminants, promoting superior adhesion.

Special Considerations for Zinc Soldering

Zinc's volatile nature and oxidation tendencies demand careful flux selection. BlackBand's formulation effectively manages zinc oxide formation while reducing metal vaporization during the soldering process.

Optimal Application Techniques

For best results with BlackBand flux:

1. Thoroughly clean all joining surfaces to remove oils, rust and oxidation
2. Apply flux evenly across the entire work area
3. Maintain appropriate temperature settings based on material and solder requirements
4. Promptly remove residues after completion using water or mild cleaners

Storage and Shelf Life

Proper storage in cool, dry conditions away from direct sunlight maintains BlackBand's performance characteristics. The product maintains full efficacy for 36 months from manufacture when stored correctly.
