Alum Leafing Paste is a metallic pigment dispersion composed primarily of aluminum flakes suspended in a carrier solvent or paste medium. It is designed to produce a high-luster, silver-like metallic finish in coatings, inks, plastics, and decorative applications. The aluminum flakes in leafing pastes are specially treated to align parallel to the surface during application, creating a reflective, mirror-like effect. This paste is commonly used in industrial, automotive, packaging, and printing industries where brilliant metallic appearance and surface coverage are essentia

SAFETY HANDLING PRECAUTIONS

Safety Handling Precautions

  • Wear gloves, goggles, and protective clothing when handling.
  • Use explosion-proof equipment in flammable environments.
  • Ensure adequate ventilation to prevent vapor accumulation.
  • Avoid contact with skin and eyes; wash thoroughly after handling.

First Aid Measures

  • Inhalation: Move to fresh air; seek medical attention if respiratory irritation occurs.
  • Skin Contact: Wash thoroughly with soap and water.
  • Eye Contact: Rinse cautiously with water for several minutes; seek medical attention if irritation persists.
  • Ingestion: Do not induce vomiting; seek immediate medical help.

Firefighting Measures

  • Fire Hazards: Flammable (due to solvent carrier); aluminum dust may be explosive in air.
  • Extinguishing Media: Use dry chemical, foam, or CO₂; do not use water on burning aluminum.
  • Special Precautions: Cool fire-exposed containers; wear full protective gear and self-contained breathing apparatus (SCBA).
