Swab or spatula can apply paste flux
CQ4300 paste flux from Chip Quik is available in 2 oz (50 g) flat jars and is designed for wire and part dipping.
It can be applied by spatula or swab to workpieces.
The paste flux is in stock at Digi-Key Electronics.
It is manufactured using high-quality synthetic resin that meets IPC J-STD-004 for REL0 (no-clean) and also can be cleaned off using hot water at +60°C plus if desired.
The ability to clean the post-soldering flux residue using just hot water is a noticeable benefit in many applications, as no strong cleaning chemicals are required.
The CQ4300 paste flux is designed to work with both leaded and lead-free alloys.
It is lead-free, RoHS, and REACH compliant.
