CX80 CX-332 molybdenum soldering paste flux core 40 g for electronics and metal repairs

CX80 CX-332 molybdenum soldering paste flux core 40 g is a compact, molybdenum-containing paste formulated for manual soldering and surface treatment of electronic components and small metal parts. The product is designed to improve heat transfer and wetting during precision rework and spot repairs, allowing controlled application where conventional liquid fluxes or rosin cores are impractical. The 40 g format is suitable for bench work and small repair jobs that require repeatable, localized fluxing.

Advantages

The paste consistency ensures minimal run-off and targeted application to joints and contact points. Molybdenum-containing chemistry supports stable thermal performance and effective activation on oxidised surfaces, improving solder wetting and joint formation. Packaging in a compact tube preserves usability and reduces waste compared with loose flux cups, while the formulation is intended for compatibility with common solder alloys used in electronic and light metal repairs.

Suitable for

• Precision electronics rework and component replacement
• Spot repairs on connectors, contacts and small metal fittings
• Restoration of oxidised contact surfaces before soldering
• Controlled manual soldering where localized flux application is required

Key specifications

• Form: paste
• Active ingredient: contains molybdenum-based components
• Net weight: 40 g
• Application method: manual application with a tool or applicator
• Intended materials: electronic components, copper, tin, and other small metal parts
• Working properties: promotes heat transfer and solder wetting

How to use

Apply a small amount of paste directly to the joint or contact area using a suitable applicator, toothpick or small tool. Position the soldering iron tip on the joint and feed solder as required; the paste supports wetting and solder flow. Use minimal paste—excess may require cleaning after soldering. Allow the joint to cool before inspecting. Follow general soldering safety practices including adequate ventilation and eye protection during use.

Usage recommendations

For best results, use with soldering irons set to temperatures appropriate for the solder alloy in use and avoid prolonged overheating of components. After soldering, remove residual flux according to the cleaning requirements of the assembly to prevent potential long-term contamination on sensitive electronics.
