Steel Jacketing Adhesive

The steel jacketing adhesive, known as ERA™300 and ERA™400, is a two-component epoxy material composed of epoxy resin and hardener. It aims to securely bond steel plates to concrete surfaces when using the steel jacketing technique. A remarkably durable material is obtained by carefully blending the epoxy resin and hardener in precise proportions. The steel jacketing adhesive is available in two variations to accommodate diverse requirements in structural reinforcement projects: low viscosity (ERA™300) and high viscosity (ERA™400). These options ensure optimal performance based on specific project needs.



  • Special epoxy base glue for steel jacket reinforcement
  • Very high initial and final adhesion strength
  • in two types of high viscosity (gel) and low viscosity (liquid)
  • It is easy to mix and use
  • Very good resistance under permanent loads
  • Adheres well to all types of concrete surfaces.
  • hardening without shrinkage (cracking)
  • Resistant to impact and temperature changes
  • Excellent chemical stability


  • The steel jacket epoxy glue, which has very high adhesive properties, is used to stick steel sheets to various types of concrete surfaces, in the steel jacket strengthening system.

Application Instructions

Application Instructions for The Steel Jacketing Adhesive:

  •  Surface Preparation: a. Ensure the concrete surfaces are clean, dry, and free from loose particles or contaminants. b. If necessary, roughen the concrete surface using suitable methods such as sandblasting or mechanical abrasion to improve adhesion.
  •  Mixing: a. Follow the manufacturer’s instructions regarding the mixing ratios and proportions of epoxy resin and hardener. b. Use clean, dry mixing tools and containers to prevent contamination.
  • Application: a. Apply a thin, even layer of The Steel Jacketing Adhesive onto the prepared concrete surface using a suitable application tool such as a brush or roller. b. Ensure that the adhesive is spread uniformly to achieve full coverage.
  •  Steel Plate Placement: a. Carefully position the steel plates onto the adhesive-coated concrete surface. b. Apply sufficient pressure to ensure good contact between the steel plates and the adhesive.
  • Additional Adhesive Application: a. Apply an additional adhesive layer over the steel plates, covering the entire surface for enhanced bonding. b. Use a suitable tool to ensure an even and uniform application.
  •  Curing: a. Allow the adhesive to cure per the manufacturer’s recommended curing time and conditions. b. Avoid subjecting the bonded area to excessive loads or stresses during curing.
  • Quality Control: a. Regularly inspect the bonded area for any signs of failure or defects. b. Conduct necessary quality control tests to ensure the adhesive’s effectiveness and adherence to project requirements.
  •  Safety Precautions: a. Adhere to safety guidelines and use appropriate personal protective equipment (PPE) during application. b. Provide adequate ventilation in enclosed areas to minimize exposure to fumes.
Guide to Quality Control (QC)

Here is a summarized guide to quality control of The Steel Jacketing Adhesive:

  •  Visual Inspection: Ensure uniform adhesive coverage for visible defects.
  •  Adhesion Testing: To assess bond strength between steel plates and concrete surfaces, perform tests.
  •  Durability Testing: Evaluate resistance to moisture, temperature, chemicals, and aging.
  •  Load Testing: Apply controlled loads to evaluate resistance to mechanical forces.
  •  Non-Destructive Testing (NDT): Use techniques to assess bond integrity without damaging the assembly.
  •  Record Keeping: Maintain detailed records of tests, parameters, and curing conditions.
  •  Compliance with Standards: Ensure procedures align with industry standards and project requirements.
  •  Regular Monitoring: Monitor performance and durability over time, and conduct periodic inspections.
    Note: Refer to manufacturer recommendations, project requirements, and industry standards for detailed guidance on quality control procedures.

Frequently Asked Questions

What is meant by steel jacket epoxy glue?

A material with a two-component structure consisting of epoxy resin and hardener. Steel jacket epoxy glue is used to stick steel plates to concrete surfaces in the steel jacketing method.

How much is the cost of epoxy glue for steel jacket?

Due to the fact that the steel sheets are glued at short distances, it is a bit difficult to glue them, so you have to get the help of a skilled and professional force, so you may have to incur a significant cost for the application of epoxy adhesives.

What is the adhesion strength of steel jacket epoxy glue?

Because concrete and steel are two types of materials with completely different properties, in order to stick them together, a material with excellent adhesion strength must be used, which provides this strength with steel jacket epoxy glue.

What is the tensile strength of steel jacket epoxy glue?

The compressive strength of the steel jacket epoxy adhesive is 90 MPa.
