This standard specifies the requirements, testing methods, and performance criteria for two-part, epoxy resin-based adhesives intended for structural applications like bonding concrete, steel, and other materials. It categorizes adhesives based on consistency and outlines mandatory physical properties for the uncured state and performance properties for the cured state.
Specifies requirements for epoxy resin-based adhesives primarily used for structural applications with concrete and other materials.
Quick Reference Values
Minimum Average Lap Shear Strength (Steel to Steel)12.0 N/mm²
Minimum Pot Life at 27°C30 min
Maximum Water Absorption (7 days)1.0 % by mass
Minimum Bond Strength (Pull-out)2.5 N/mm² or failure of concrete
Practical Notes
Surface preparation (cleaning, roughening, and drying) is absolutely critical to achieve the specified bond strength.
Adherence to the manufacturer's specified mix ratio of resin to hardener is crucial; incorrect ratios will lead to incomplete curing and poor performance.
Pot life and curing time are highly sensitive to ambient temperature; higher temperatures reduce pot life and accelerate curing.
