Products
7 categories, 37 grades; all or most meet RoHS requirements.
Flux Soldering Flux (8)
No-clean, water-soluble, aluminium, stainless, pre-coating and HASL grades - all RoHS compliant.
Resin-Type No-Clean Flux
Medium-solids resin no-clean flux. Pale film, high gloss, very little fume - ideal for lines without extraction.
Water-Soluble Flux
High activity, fast wetting - even heavily oxidised terminations tin in one pass. Residue washes off with plain water.
General-Purpose Resin Flux
For hand iron and wave soldering; runs on low-cost S502/602 solder to cut manufacturing cost.
Pre-Coating Flux
PCB pre-coating for oxidation protection and solderability. Very high activity; F119 is the low-solids grade for dense and multilayer boards.
High-Activity Aluminium Soldering Flux
Developed for aluminium-to-copper replacement in electrical work. Joins Al+Al, Al+Cu, Al+Fe/stainless, Al+Ni, Al+Zn and their alloys.
Stainless Steel Flux
Water-soluble flux for tinning stainless pins on connectors; even heavily oxidised areas tin in one pass, residue rinses off with water.
High-Activity Flux (Electrical Grade)
The go-to grade for simple high-activity electrical work; typically paired with low-cost S502/602 wire.
HASL Solder Flux
Flux made for the PCB hot-air-solder-levelling (HASL) stage: high activity, easy-to-clean residue. F102 is the alternative grade.
Paste Solder Paste (2)
Lead-free P3 series (incl. SnBi58 low-temp) and leaded P1 series - printability and solderability together.
Lead-Free Solder Paste P3 Series
Fine powder, good printability, slow to dry out, excellent solderability and very little residue. SnAg0.3Cu0.7 standard and SnBi58 low-temperature grades.
Leaded Solder Paste P1 Series
Bright, full fillets. P105-X prints continuously for 12h down to 0.3mm pitch; P105-T wets better and handles 0.2mm fine pitch.
Bar/Wire Solder Bar & Wire (4)
Lead-free SnCu/SnAg/SnAgCu and leaded anti-oxidation grades, φ0.1-7mm, special alloys to order.
SnCu Lead-Free Solder Bar
Premium low-cost SnCu bar for wave soldering and tinning. With F118E/P it delivers quality close to leaded Sn63.
Leaded Anti-Oxidation Solder Bar
High-temperature anti-oxidation SnPb bar made for tinning. Very low fume, no pungent smell, no-clean for general consumer electronics.
Lead-Free Activated Solder Wire
General and special lead-free activated wire, φ0.1-7mm, in Sn-Cu, Sn-Ag, Sn-Ag-Cu, Sn-Ag-Cu-Sb plus ultrafine grades.
Leaded Solder Wire
Full range from premium general-purpose to ultra-low-cost, solid or resin-cored (RMA / no-clean R / water-soluble W), including loudspeaker and consumer-electronics grades.
Clean Surface Cleaning Agents (7)
PCBA cleaner, economy cleaner, wiping solvent, white spirit, mesh wash & retarder, aqueous wash additive.
W118 PCBA Cleaner (No-Clean Residue Remover)
CFC-free and formulated to EU RoHS. Colourless, virtually odourless, and it shifts the residue of virtually every mainstream leaded and lead-free flux.
Economy Grade PCBA Cleaner
Budget cleaner for lines where low odour is not critical; still shifts ordinary rosin-flux residue.
Wiping Solvent (Machine Wipe)
Fast-evaporating wiping solvent for plant, jigs and part surfaces; leaves no water marks.
Industrial Cleaning Solvent (White Spirit Type)
General-purpose industrial cleaning solvent for degreasing, wiping and thinning; SGS/CTI test data available.
Screen Printing Mesh Wash
Mesh cleaner for screen printing: strong solvency, safe on stencil emulsion and mesh, shifts dried ink fast.
Screen Ink Retarder (783)
Retarder that slows ink drying on the screen, preventing clogging and broken lines for steadier printing.
Electronic Component Aqueous Wash Additive
Water-based wash additive that boosts removal of water-soluble flux residue and ionic contamination while cutting solvent use.
Strip Paint & Enamel Strippers (7)
Immersion, brush, plastic-safe and magnet-wire strippers plus universal powder - from room temp up to 220C class enamel.
Immersion Type Paint Stripper
General immersion stripper for the coatings trade: shifts alkyd, nitro, amino, acrylic and epoxy films, and clears paint from plastic parts.
Fast Immersion Paint Stripper
Built for high-strength epoxy, powder-coat and e-coat finishes; fast acting and will strip PCB solder mask right off.
Plastic-Safe Stripper / Ink Remover
Made to lift paint and screen-printed markings off plastic parts without attacking the substrate.
Brush-Type Fast Paint Stripper
For spot stripping and repair - large parts that cannot be immersed, and localised PCB solder-mask removal.
Enamelled-Wire Fast Stripper
Made for localised stripping of magnet wire - shifts most enamel films in 0.5-2 min and still works above 0C in winter.
Universal Enamelled-Wire Stripping Powder
Shifts every type of high-temperature magnet-wire enamel with no grade selectivity, and markedly improves core solderability afterwards - especially valuable on aluminium wire.
High-Temperature Magnet-Wire Stripper Series
Designed for high temperature-class magnet wire: strips at room temperature, CC-4X goes up to 220C class, CC-4M is for automatic lines.
▸ Dross Reducer & Auxiliaries (4)
Online dross reducer, flux thinner, wire activator, plus analysis and process diagnostic services.
Online Dross Reducing Agent
Used in the pot: cuts dross down to 50-30% of normal levels, saving solder and reducing skimming frequency.
