Paint Drier is a specialized industrial additive designed as a non-toxic, lead-free alternative to traditional lead-based paint driers. It contains 36% active metal content primarily composed of bismuth and other metals, formulated to accelerate the drying and curing process of oil-based paints, varnishes, and coatings. The product improves film formation, reduces drying times, and enhances the durability and gloss of finished surfaces without the health and environmental hazards associated with lead compounds. BxPB36% Paint Drier is commonly used in architectural, industrial, and automotive coatings as a safer substitute for lead-based driers.

Paint Drier

Primary Uses

Paint and Coatings Industry
- Serves as a catalytic drying agent (paint drier) in alkyd, oil-based, and other solvent-based coatings.
- Enhances oxidative polymerization, enabling faster drying and curing of paints and varnishes.
- Improves surface hardness, gloss, and overall coating performance.
Automotive and Industrial Coatings
- Used in automotive refinishing paints and industrial protective coatings to reduce downtime by accelerating dry times.
- Improves adhesion and weather resistance of coatings on metal and wood substrates.
Architectural Paints
- Applied in house paints, stains, and lacquers to speed up drying times and improve finish quality.

Secondary Uses

Ink Formulations
- Occasionally used as a drying catalyst in some solvent-based printing inks.
Marine Coatings
- Utilized in specialty marine paints requiring fast drying and corrosion resistance.
Wood Finishing
- Employed in wood varnishes and sealants to accelerate curing and enhance durability.

First Aid Measures

Inhalation: Move to fresh air immediately; seek medical attention if symptoms persist
Skin Contact: Wash affected area thoroughly with soap and water; seek medical advice if irritation develops
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes; seek medical attention if irritation persists
Ingestion: Rinse mouth; do not induce vomiting; seek immediate medical attention

Firefighting Measures

Fire Hazards: Flammable due to solvent base; vapors may form explosive mixtures with air
Extinguishing Media: Use foam, dry chemical, CO₂, or water spray as appropriate
Special Precautions: Firefighters should wear full protective gear and self-contained breathing apparatus (SCBA)
Decomposition Products: May emit toxic fumes including metal oxides and carbon monoxide during combustion
