4. Applications
- Reaction Catalyst: Lewis acid catalyst for esterification, transesterification, condensation and addition reactions; Ziegler-Natta catalyst for polymerizations (polyester, plasticizer, polyurethane production)
- Coatings: Enhances surface hardness, adhesion, scratch resistance; provides coloring effects, light reflection, iridescence, and corrosion resistance
- Paint Additive: Cross-links -OH functional polymers/binders, promotes adhesion, acts as a binder
- TiO₂ Pigments & Films: Forms micro/nano-scale TiO₂ pigments; creates polymeric TiO₂ films via pyrolytic or hydrolytic (sol-gel) processes
5. Handling and Usage
- Formulate with other ingredients in catalysis, cross-linking, or paint applications; add as the last ingredient to prevent undesired pre-reactions with water
- For adhesion promotion/surface modification, apply as a primer from dilute solution
- In coating applications, form thin polymeric TiO₂ layers via thermal or hydrolytic processes
- In sol-gel applications, total/partial hydrolysis (with other metal alkoxides) yields metal oxide systems for binders/coatings
6. Packaging & Storage
- Packaging: 25kg or 200kg drum
- Storage: Store in a cool, dry, well-ventilated area, tightly sealed to prevent moisture exposure
- Shelf Life: 2 years under proper storage conditions
7. Safety & Handling
- Hazard Classification: Flammable liquid; moisture-sensitive; irritant to skin, eyes, and respiratory tract
- Recommended PPE: Safety goggles, chemical-resistant gloves, and protective clothing
- Precautions: Use in well-ventilated areas; avoid contact with water/moisture; keep away from heat sources and incompatible materials
- For complete safety information, refer to the current Material Safety Data Sheet (MSDS)
8. Test Methods
