Applications
- Catalyst in Polymer Synthesis
- Saturated Polyester Resins: Used in powder coatings, coil coatings, and insulating paints to catalyze polyester condensation reactions.
- Unsaturated Polyester Resins: Accelerates cross-linking during curing.
- PBT Engineering Resins: Promotes esterification in polybutylene terephthalate synthesis.
- Stabilizer in Plastics & Coatings
- PVC Stabilizer: For food-contact packaging materials, it prevents thermal degradation, improves heat resistance and transparency, and complies with regulations like GB 9685-2016 (China).
- Industrial Coatings: Enhances adhesion and corrosion resistance in protective coatings.
Chemical Properties
- Solubility: Soluble in organic solvents (e.g., toluene, acetone); insoluble in water.
- Thermal Stability: Stable under normal processing conditions but may decompose at high temperatures (>200°C).
- Reactivity: Hydrolyzes slowly in the presence of moisture, releasing 2-ethylhexanoic acid and butyltin species.
Safety and Regulations
- Toxicity: Toxicity depends on exposure dose; acute effects may include skin/eye irritation. Chronic exposure risks are regulated due to potential environmental accumulation.
- Regulatory Standards:
- China: GB 9685-2016 specifies migration limits for food-contact materials.
- EU: Listed in REACH for potential restrictions based on environmental hazard assessments.
- Handling Precautions:
- Use in well-ventilated areas; wear protective gloves and eyewear.
- Store in sealed containers away from moisture and strong acids.
Environmental Considerations
- Biodegradability: Slowly degraded in aquatic environments; may bioaccumulate in organisms.
- Disposal: Follow hazardous waste regulations; incineration under controlled conditions to prevent tin oxide emissions.
