Rosin Flux Paste 50 g

This rosin-based flux paste cleans metal surfaces and prevents oxidation during soldering. It acts as a wetting agent so solder flows smoothly and forms reliable electrical and mechanical bonds. The 50 g container suits bench technicians and hobbyists who need consistent flux performance for electrical work.

Suited for general electrical soldering.

The paste is formulated for standard electrical soldering tasks such as wire tinning, component replacement and PCB repair. It does not contain the activators required for stainless steel, aluminium or high-reliability aerospace assemblies. Users who need water-soluble, no-clean or acid-core fluxes for those applications should select a different product.

50 g net weight

The jar holds 50 grams of flux paste, which determines how many joints can be completed before replenishment. Buyers should match this quantity to their typical project volume to avoid running out mid-task.

Questions about this item

Should I choose the 50 g tub or a larger size for occasional soldering?

The 50 g tub is the only size offered for this Delcast rosin flux paste, so it covers both occasional and regular use without needing a larger container.

What does the 50 g weight mean for how long the flux will last on my bench?

A 50 g tub provides enough flux for many soldering sessions; a small dab per joint means it typically lasts months for hobbyists and weeks for daily technicians.

Is this rosin flux compatible with standard leaded and lead-free solder alloys?

Yes, the Delcast rosin flux works with both traditional leaded and modern lead-free solders, cleaning oxidation and improving wetting on copper tracks and component leads.
