Instructions for Use:

This product should only be handled by trained personnel.

Handling and disposal should be carried out in places with local or comprehensive ventilation and exhaust facilities, avoiding eye and skin contact and inhalation of vapor. Use explosion-proof ventilation systems and equipment.

This product needs to be mixed with matching Component A and Component B in a certain ratio for cross-linking curing to form the final product.

This product reacts violently with acids, bases, and oxidizing agents, etc. Avoid contact with incompatible substances.

Depending on different usage requirements, the usage of KuberdBond®620 Component A and Component B in the formulation can be adjusted.

Storage:

• Shelf Life: Unopened containers stored at 18-25°C indoors have a minimum shelf life of 18 months.
• Store in a cool, well-ventilated warehouse. Operators should undergo specialized training and strictly follow operating procedures. Keep away from flames, heat sources, and no smoking in the workplace. Use explosion-proof ventilation systems and equipment. If containerized, control flow rate and ensure grounding to prevent static buildup. Avoid contact with incompatible substances. Handle with care during transportation to prevent damage to packaging and containers. Empty containers may contain harmful residues. Wash hands after use and no eating or drinking in the workplace. Equip with appropriate types and quantities of firefighting equipment and leakage emergency handling equipment.

First Aid Measures

Generally, present this safety data sheet to the doctor at the scene.

• Inhalation

If inhaled, move the patient to fresh air.

• Skin Contact

Remove contaminated clothing, thoroughly wash skin with soap and water. If discomfort persists, seek medical attention.

• Eye Contact

Separate eyelids, rinse with flowing water or saline. Seek medical attention immediately.

• Ingestion

Rinse mouth, do not induce vomiting. Seek medical attention immediately.

Firefighting Measures

Fire Extinguishing Media

Suitable extinguishing agents:

Use water mist, dry powder, foam, or carbon dioxide extinguishing agents. Avoid using direct water stream, as it may cause splashing of flammable liquids, spreading the fire.

Leak Handling

• Personal Precautions, Protective Equipment, and Emergency Procedures

Emergency responders are recommended to wear self-contained breathing apparatus, anti-static clothing, and oil-resistant rubber gloves. Avoid contact with or crossing over the leak. All equipment used in the operation should be grounded. Cut off the leak source as much as possible. Eliminate all ignition sources. Establish a caution zone based on the area affected by liquid flow, steam, or dust dispersion. Non-essential personnel should evacuate from the side wind or upwind to a safe area.

• Environmental Protection Measures

Contain the leaked substance to prevent environmental contamination. Prevent leaked substance from entering sewers, surface water, and groundwater. Methods for containing and clearing leaked chemicals and disposal materials.

Small leak: Collect leaked liquid in a sealable container if possible. Absorb with sand, activated carbon, or other inert material, and transfer to a safe place. Do not flush into sewer.

Large leak: Build dikes or dig pits for containment. Close drainage pipes. Cover with foam to suppress evaporation. Transfer to tank truck or dedicated collector using an explosion-proof pump, recycle or transport to a waste disposal site for disposal.
