EP 325

Solvent-free, High Viscous Epoxy Resin for Crack Injection System

EP 325 is a two-component, moisture-insensitive, epoxy resin-based crack injection system designed for sealing cracks in concrete and restoring structural integrity. It is particularly effective for grouting cracks ranging from 0.5 mm to 10 mm in width, cold joints, and other similar defects in concrete structures.

Features

EP 325 offers excellent bond strength, ensuring the restoration of structural integrity. Its high elastic modulus allows for effective stress transfer at the bond interface. The product is moisture-insensitive, making it versatile for various applications, and it provides resistance to a wide range of chemicals and liquids. Pre-proportioned components ensure consistent performance during application.

Substrate Preparation

The surface to be treated with EP 325 must be hard, sound, and free from dust, paint, lime coatings, plaster, curing agents, laitance, adhesive residues, and other materials that may inhibit adhesion. The area should be prepared by drilling appropriate holes and fixing injection packers or nipples. The holes must be free of debris and laitance before fixing the packers. Ensure that the entire length of the crack is sealed using a suitable adhesive.

Application

EP 325 should be injected into cracks and joints using a high-pressure, airless double diaphragm pump or a two-component piston pump designed for epoxy injection. Begin by injecting the mixed material into each port or nipple, ensuring that all other ports remain closed. When the resin starts to emerge from the next port, close it and continue the injection process. Repeat this until all ports are filled. After 24 hours, remove all the nipples or ports and fill the resulting cavities with a suitable epoxy adhesive.
