Full definition
A seamless, chemically resistant floor system created by applying two-component epoxy resin (resin + hardener) directly onto prepared concrete substrates. Epoxy forms a hard, dense, non-porous surface that resists chemicals, abrasion, and impact. System types by thickness: (1) Thin-film coating (0.3-0.5 mm) — economical protection for light-duty. (2) Self-leveling (1.5-3 mm) — smooth, seamless, aesthetic finish for commercial and pharmaceutical. (3) Mortar/screed (3-12 mm) — maximum chemical and impact resistance for heavy industry, with quartz or aluminum oxide aggregate. (4) Novolac epoxy — maximum chemical resistance for acid/solvent exposure. Surface options: smooth (gloss or matte), non-slip (broadcast quartz aggregate or aluminum oxide), and decorative (color flake, metallic, terrazzo). Chemical resistance: excellent to acids, alkalis, solvents, oils (varies by formulation — novolac grades resist the broadest range). Limitations: brittle (cracks with substrate movement — use PU for crack-bridging), poor UV stability (yellows/chalks in sunlight — use aliphatic PU topcoat outdoors), and slippery when wet unless textured. Per ASTM C722 (epoxy resin lining) and SSPC Guide 12. Applications: manufacturing plants, warehouses, laboratories, pharmaceutical, food processing, commercial kitchens, aircraft hangars, and parking garages.
