RoHS/Reach certified, compliant with cleaning agent VOC standard (GB38508).
BT-705 Aluminum Flux: Removes oxide layer on aluminum surfaces, used for soldering voice coils, motors, transformers, and other aluminum wires. Extremely low corrosion rate on aluminum wires (less than 1% in 7-day immersion test).
BT-706 Copper Flux: Specifically for soldering copper wires (round or flat), ensures full solder coverage and prevents icicle formation.
BT-707 Direct Solder Agent: Enables one-step de-enameling and soldering for copper/aluminum enamel wires with heat resistance classes 130 (B) and 155 (F).
