Isopropylideneglycerol Acrylate (IPGA): Advanced Monomer for Next-Generation Photopolymers
*CAS 13188-82-4 | Molecular Formula: C₉H₁₄O₄ | MW: 186.20 g/mol*
Technical Profile
IPGA is a key acrylate monomer engineered for UV-curable systems. Its unique molecular structure delivers:
-
Ultra-Low Viscosity: 4.09 mPa·s at 25°C (smoother than water)
-
Enhanced Reactivity: Accelerates curing kinetics by >30% vs. standard acrylates
-
Subzero Flexibility: Tg = -7°C maintains elasticity in cryogenic environments
Core Performance Advantages
1. Photopolymerization Catalyst
When formulated into UV resins, IPGA reduces curing time by ≥30% while achieving nanometer-scale surface smoothness. Ideal for:
-
High-precision 3D printing (0.01mm resolution)
-
Screen printing inks
-
Optical coatings
2. Universal Adhesion Promoter
Blends with polyurethane resins (30% loading) enable 100% adhesion on glass/aluminum substrates. Critical for:
-
Automotive sealants
-
Pressure-sensitive adhesives
-
Aerospace composites
3. Environmental Resistance
Molecular design provides exceptional:
-
UV stability (ASTM G154 certified)
-
Thermal endurance (continuous 110°C service)
-
Radiation shielding (3× improvement in vacuum environments)
Sustainable Production Process
IPGA synthesis exemplifies green chemistry principles:
| Step | Innovation | Benefit |
|---|---|---|
| Feedstock | Bio-based glycerol replaces petrochemicals | 30% lower carbon footprint |
| Catalysis | Acid-base synergistic system | 45% energy reduction (80°C/atm pressure) |
| Purification | Molecular distillation + crystallization | 99.5% purity (impurities <0.01%) |
