Packaging, shipping and storage
1. BT-706 copper flux has 2 packaging specifications, 1L/bottle or 20L/drum;
2. Store in a closed container below 25°C. Its product is a volatile liquid, the weight will gradually decrease, and the shelf life is 6 months;
3. When storing products, ventilation and dryness should be ensured, preventing direct sunlight from them, and isolating fire sources and staying away from heat sources.
4. During transportation, it should be protected from sun exposure, rain, high temperature, leakage, extrusion, and crushing.
Notes:
1. When opening the cap, be careful to press the cap with the air pressure in the bottle, wear gloves and gently press the cap, and slowly unscrew it to avoid splashing the eyes and skin.
2. The flux activity is high, if the smoke smokes to the bottom plate or other parts, it is recommended to clean it with water.
3. Pay attention to safety when using, wear protective gloves, protective masks, masks, clothing and glasses, and do not touch the skin to avoid splashing the eyes and skin.
Regardless of transportation, storage, and use, you need to take the initiative to request MSDS from our company to clarify the physical and chemical safety performance.
