This standard specifies the requirements for two-component epoxy resin systems, including the resin, hardener, and the mixed composition intended for use as a seamless floor topping. It covers material properties, performance characteristics like compressive strength, bond strength, and abrasion resistance, as well as test methods.
epoxy resin, hardeners and epoxy resin compositions for floor topping
Quick Reference Values
Minimum Compressive Strength (7 days)60 N/mm²
Maximum Abrasion Resistance (Wear)0.2 g
Minimum Pot Life30 minutes
Minimum Bond Strength to Concrete2.0 N/mm²
Maximum Water Absorption (24h)0.5 % by mass
Practical Notes
Substrate preparation is critical for achieving the specified bond strength; the concrete surface must be clean, dry, and mechanically prepared (e.g., by shot-blasting).
Always mix components in the exact proportions specified by the manufacturer, as incorrect ratios lead to incomplete curing and failure.
Pot life is heavily dependent on ambient temperature; higher temperatures will significantly accelerate the reaction and reduce working time.
