Epoxy Resins Engineering Grade Thermosets For Extreme Performance
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
