Avoid further exposure until ventilation and spray conditions are controlled.
Skin Contact:
Remove contaminated clothing and wash skin thoroughly with soap and water.
Seek medical advice if irritation, redness, or dryness develops or persists.
Wash contaminated clothing before reuse.
Eye Contact:
Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists or if exposure is significant.
Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek medical attention or contact a poison center if discomfort occurs.

HANDLING AND STORAGE
Handling:
Use appropriate PPE including chemical-resistant gloves, safety goggles, and protective clothing.
Avoid breathing spray mist or aerosol during mixing, spraying, and coating application.
Mix water-emulsifiable polyisocyanate carefully into MACRYNAL VSM 2521w/42WAB according to formulation procedure to maintain pot life and film quality.
Ventilation:
Use local exhaust ventilation during spraying, mixing, and drying operations.
Avoid handling in confined spaces without adequate airflow.
Use respiratory protection where spray mist exposure cannot be adequately controlled.
Storage:
Store in tightly closed containers in a cool, frost-free, well-ventilated area.
Protect from freezing, excessive heat, direct sunlight, evaporation, and microbial contamination.
Keep away from strong acids, strong bases, strong oxidizers, and incompatible reactive chemicals.
Spill and Leak Procedures:
Contain spill with inert absorbent and prevent entry into drains.
Collect into suitable containers for reuse or disposal according to local regulations and facility procedures.
Clean remaining residue with water before drying if allowed by facility procedure.
