Industrial Epoxy Adhesives are high-strength structural compounds based on epoxy resins (ED-20, ED-22, Bisphenol A diglycidyl ether). Bond strength is 15–40 MPa (shear). Adhesion to metals, glass, ceramics, concrete, composites. Two-component (2K): resin + amine/polyamide hardener, cures at 20°C in 20–120 min. One-component (1K): latent hardener, activated at 120–180°C — for conveyor production. GOST 30535-97. Packaging: cans 0.5–5 kg, buckets, cartridges. For critical joints: epoxy adhesives are certified for aviation (EASA), bridge construction (ETA), nuclear energy. Surface preparation: degreasing + abrasive treatment (Ra 40–60 µm). 2K storage: base — 24 months, hardener — 12 months. Storage temperature ≤25°C. Documentation: TDS, MSDS, bond strength protocol.
