1. Precursors for Hot-End Coating of Glass Containers (Core Application) 🥤:
High-temperature decomposition generates a tin oxide film, improving wear resistance, scratch resistance, thermal shock resistance, and pressure resistance; typical products: beer bottles, beverage bottles, food cans, medicine bottles, laboratory beakers/test tubes; key points: control the spraying amount and furnace temperature curve to ensure uniform film layer and adhesion.

2. Organotin Intermediates (Synthesis Platform) ⚗️:
Preparation of dibutyltin/tributyltin series catalysts, stabilizers, antifouling agents, and pharmaceutical/pesticide intermediates; typical products: DBTDL, DBTA, thiolates, carboxylates; key points: highly corrosive and hydrolytic, the process requires anhydrous conditions, inert atmosphere, and corrosion-resistant equipment.

3. Catalysts for Catalysis and Condensation/Esterification/Transesterification 🧪:
Accelerates transesterification, esterification, silane polycondensation, and PU/silicone crosslinking; typical fields: plasticizer, lubricant, and antioxidant synthesis, PU foam/coatings/adhesives, silicone sealants; key points: conduct small-scale tests first to verify activity and by-products, control pH and sulfur/amine impurities.

4. PVC Heat Stabilizer Precursors and Auxiliary Stabilizers 🧩:
Synthesis of butyltin heat stabilizers, or directly assisting in inhibiting HCl degradation; typical products: rigid PVC pipes/profiles/sheets, flexible PVC films/cable materials; key points: often compounded with lubricants and antioxidants to optimize processing window and initial coloration.

5. Antifouling and Preservative (Restricted Use) 🛡️:
Marine antifouling coatings, wood preservatives, rodent-repellent cable coatings; typical scenarios: hull antifouling, outdoor wood protection, cable rodent protection; key points: strong aquatic toxicity and bioaccumulation, strictly comply with environmental protection and restricted use regulations, prioritize the use of alternatives.

6. Specialty Glass and Functional Layer Modification 🪟:
Thermal end coatings for automotive glass, solar glass, and borosilicate heat-resistant glass to improve compatibility with functional films, weather resistance, and heat resistance; Key points: Matching with the coating process, verifying stability and adhesion at high temperatures.
