5. Precautions for use:
Operators should first refer to the Safety Data Sheet (SDS). This product should be kept away from heat sources, sparks, and open flames. In a sealed environment, adequate ventilation should be maintained. During operation, protective measures should be taken, and smoking is prohibited. If the product comes into contact with the eyes, there may be a slight discomfort, which can be reduced by rinsing with water. Prolonged contact with the substance is prohibited. Polyurethane materials are sensitive to moisture and should be stored in seal when not in use. Do not bake for extended periods, as this may affect the product's performance. Before use, component B must be fully stirred to ensure a homogeneous state of the material solution.
