Butyltin Trichloride Application:


1. Glass Industry

*Glass Strengthener: Surface coating enhances glass strength for applications in construction, automotive, and home appliances.

*Hot-End Spray: Serves as a protective coating for the hot end of glass containers such as beer bottles to prevent softening and deformation during production.


2. PVC Stabilizer Intermediate

*Used in the synthesis of organotin-based PVC heat stabilizers, improving PVC processing stability and heat resistance.


3. Anticorrosion and Mildew Control

*Wood Preservation: Inhibits fungal growth and extends the life of wood.

*Marine Paint: Serves as an antifouling coating component to prevent marine organisms from attaching.


4. Organic Synthesis Catalyst

*Introduces tributyltin groups for the synthesis of tin-containing organic compounds (such as antioxidant 618).
