Epoxy resins are thermosetting polymers characterized by epoxide groups bonded to aliphatic, cycloaliphatic, or aromatic chains, delivering unmatched adhesion, chemical resistance, and dimensional stability. Engineered for mission-critical applications, our formulations provide:
✅ Ultimate Adhesion Strength (≥10 MPa) – Hydroxyl enable covalent-level bonding to metals/composites
✅ Chemical Inertness – Withstands 10% H₂SO₄/HCl/CH₃COOH (2 years) & 10% NaOH (100°C/1 month)
✅ H-Grade Insulation – Dielectric strength >35 kV/mm, ideal for high-voltage transformers
✅ Near-Zero Shrinkage (1-3%) – Dimensional stability for precision tooling (±0.1% with fillers)
✅ Multi-Phase Versatility – Liquid (low-visc), solid (high-Tg), and water-based eco-formulations
| Industry | Critical Applications | Advanced Formulations | Performance Advantage |
|---|---|---|---|
| Electronics | IC Encapsulation/Transformer Potting | Hydrogenated Bisphenol A Resin | Tg >200°C, weathering resistance ↑200% |
| Energy Infrastructure | Wind Turbine Blades/Bridge Coatings | Novolac Epoxy + Glass Flake Composite | Resists 150°C wet flue gas corrosion |
| Transportation | Automotive Chassis/Aerospace Composites | Flexible Vinyl Ester Laminates | Fatigue strength ↑200%, elongation >5% |
| Industrial Coatings | Tank Linings/Anti-corrosive Flooring | Bisphenol A Resin + CYD-128F System | Abrasion resistance ↑50%, compressive strength ≥12kN |
| Microelectronics | LED Packaging/PCB Substrates | Alicyclic Resin (Celloxide 8010) | Low viscosity (60mPa·s), Tg 354°C |
| Adhesives | CFRP Bonding/Structural Joints | Dicyandiamide Latent Curing System | 120°C rapid cure, 4-month RT latency |
Selection Protocol:
- Extreme Heat (>300°C) → Alicyclic Epoxy (Tg 354°C, zero decomposition)
- Food/Grade Compliance → Hydrogenated Bisphenol A (BPA-free, FDA 21CFR 175.300)
- UV/Weather Resistance → Novolac Modified Resin (anti-yellowing efficiency ↑300%)
