Tin-Free Catalysts
What are catalysts? Catalysts accelerate chemical reactions during curing. In coatings, organotin catalysts have long been used to promote crosslinking in polyurethanes and epoxies. However, they pose health and environmental risks.
Industry Challenge:
- Stricter environmental regulations limit organotin use.
- Automotive OEMs are moving toward green chemistry.
- Need for catalysts that balance cure speed, durability, and safety.
Solution – Tin-Free Catalysts:
- Acid catalysts and blocked acid catalysts promote curing of melamine, epoxy, and polyester systems.
- Tin-free urethane catalysts achieve similar performance without toxic tin.
- Safer for workers, greener for the environment, compliant with REACH and FDA standards.
Key Benefits:
- Faster curing → higher production efficiency
- Stronger film durability, corrosion and fuel resistance
- Safer, eco-friendly compliance with global standards
Applications: Automotive coatings, industrial enamels, adhesives, coil coatings.
