Features
EP 21 G is a high-performance, moisture-insensitive, free-flowing epoxy resin grout designed for heavy-duty applications. It offers excellent adhesion to both cement and metal substrates and is particularly suitable for grouting bridge bearing plates, machine bases, fixing bolts and anchors, and vertically placed dowel bars, even under dynamic loading conditions.
Characteristics / Advantages
EP 21 G provides several beneficial properties, including high early strength, shrinkage-free curing, and excellent adhesion to various substrates. It is easy to apply, even in challenging conditions, and its free-flowing nature ensures that it fills voids and gaps effectively.
