Product Introduction

Elastic Concrete is a high-performance, epoxy-based polymer concrete composed of three parts:

Component A: Elastic epoxy resin

Component B: Toughened epoxy hardener

Component C: Specially-graded high-performance aggregate

Unlike traditional polyurethane-based flexible concretes, this epoxy formulation offers superior adhesion, mechanical strength, and chemical durability, making it ideal for structural repairs in extreme conditions such as highways, rail tracks, bridge joints, and airport runways.
