Product Introduction
RG Epoxy Polymer Mortar is a high-performance protective mortar combining epoxy resin, polymer additives and graded aggregates. It forms a dense, durable and corrosion-resistant layer strongly bonded to concrete substrates. The system provides excellent resistance to impact, abrasion, cavitation, carbonation and chemical attack, making it ideal for hydraulic structures, ports, bridges, industrial floors and chemical plants. With superior durability, RG mortar ensures long service life and stable protection in aggressive environments.
