matters needing attention
1. Read the instructions before construction. Or consult the manufacturer, dry spraying is easy to occur in high temperature seasons. To prevent dry spraying, diluent must be used for dilution.
2. The substrate temperature is more than 3 ℃ higher than * point, and the construction temperature is not lower than 5 ℃
3. This product is flammable. During construction, pay attention to keep the site ventilated, take fire prevention, anti-static and other safety measures, and carry out construction in strict accordance with the safe operation procedures
4. When the temperature is lower than 5 ℃, quick drying curing agent is required
5. Due to the high density of red lead, it is easy to sink to the bottom, so it needs to be fully stirred during use.
5. The above data are accumulated in the laboratory for reference only.
Precautions:
Keep away from heat sources, sparks, open flames and hot surfaces. No Smoking. Keep container closed. The container and receiving equipment are grounded and connected. Use explosion-proof electrical appliances, ventilation and lighting equipment. Only use tools that do not produce sparks. Wear protective gloves, eye protection and face shield.
Waste disposal: the disposal of this product and container shall be carried out in accordance with the requirements of relevant local laws and regulations.
