📊 Typical Technical Data
⚠️ The values below are for reference only and must not be used for specification or quality control without prior written confirmation from our technical team.
Parameter Specification Appearance Slightly yellow liquid Purity ≥ 98% Tin Content (%) ≥ 15 – 16% Moisture Content ≤ 1.0% Density (25°C) 1.468 ± 0.002 g/cm³ Volatile Content ≤ 0.4%
🌱 Key Advantages
- Non-toxic & eco-friendly alternative to traditional butyltin-based stabilizers
- Longer alkyl chains (C₈ vs C₄) enhance compatibility and reduce volatility
- Compliant with evolving environmental and regulatory standards for consumer plastics
🌐 Applications
USi-DOTL serves dual roles as a heat stabilizer and catalyst across multiple industries:
✅ In PVC Processing:
- Acts as a non-toxic heat stabilizer for food-contact, medical, and toy-grade PVC products
- Provides excellent long-term thermal stability and color retention
✅ In Polyurethanes:
- Efficient gelling catalyst for coatings, adhesives, sealants, and elastomers (CASE)
✅ In Silicone Systems:
- Functions as a curing agent for organic silicone resins, enabling room-temperature crosslinking
Its “greener” profile makes it ideal for manufacturers seeking sustainable performance without compromising efficiency.
