FIRST AID

Inhalation:
Move to fresh air if vapors or mists are inhaled.
Seek medical attention if respiratory irritation persists.

Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek medical attention if discomfort occurs or if a significant amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves and safety glasses for bulk handling.
Avoid splashing into eyes and avoid prolonged skin contact.
Use clean dosing equipment and avoid contamination of storage containers.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust if spraying, heating, or mist generation is possible.
Avoid aerosol formation in enclosed spaces without adequate airflow.

Storage:
Store in tightly closed containers in a cool, dry, well-ventilated area.
Protect from freezing and excessive heat if the grade is temperature sensitive.
Keep away from strong oxidizers and incompatible chemicals.

Spill and Leak Procedures:
Contain spill and absorb with inert material.
Clean residue promptly because liquids can create slip hazards.
Dispose of waste according to local regulations and facility procedures.

Handling Precautions:
Optimize dosage because dispersant and rheology performance can invert at high levels, leading to instability, foaming, or viscosity issues.
Verify compatibility with the resin and pigment package because different pigment chemistries require different adsorption behavior and stabilization mechanism.
Rotate stock using FIFO practices to maintain consistent quality and predictable dispersion and rheology performance.
