Rosin 40g flux with the addition of activators to facilitate soldering
Description
Rosin flux 40 g with activators makes soldering easier and improves wetting. The no-clean formula minimises cold joints and delivers durable, clean connections for electronics and electrical work.
Advantages and unique features
- Active chemistry for faster wetting and solder flow
- No-clean – residues usually require no cleaning
- Stable across a wide operating temperature range
- High chemical purity, low ash content
- Complies with flux quality standards (ISO & J-STD)
Properties and applications
- Electronics: PCB assembly/repair, wires and THT parts
- Service: better tin-lead joints and training use
- Labs/R&D: base for reference flux solutions (25% in IPA)
- Effect: oxide removal, improved wetting, fewer cold joints
