Introduction
Isophorone Diisocyanate (IPDI)
Chemical Formula: C₁₂H₁₈N₂O₂
Classification: Diisocyanate with two reactive isocyanate groups (-N=C=O).
Physical Form: Colorless to pale yellow liquid; derived from isophorone (cyclic ketone).
Key Features: UV-resistant, non-yellowing, and stable under harsh conditions.
Properties
- Reactivity:
- Reacts vigorously with active hydrogen-containing compounds (e.g., alcohols, amines).
- Stability:
- Resistant to UV light and weathering; ideal for outdoor use.
- Solubility:
- Soluble in organic solvents; reacts with water.
Applications
- Polyurethane Production:
- Key raw material for polyurethane coatings, adhesives, and elastomers.
- Coatings:
- Enhances durability and flexibility in automotive, industrial, and wood coatings.
- Adhesives & Sealants:
- Improves performance in high-strength adhesives and sealants.
- Specialty Polymers:
- Used in light-stable, weather-resistant polymers (e.g., aerospace materials).
Safety Considerations
- Toxicity: Toxic and a respiratory irritant.
- Handling: Requires proper ventilation, gloves, and protective equipment.
Summary:
IPDI’s reactivity, stability, and UV resistance make it indispensable in polyurethanes, coatings, and adhesives. Despite its industrial value, strict safety protocols are essential due to its toxicity.
