FİXA REPOX 405: High Strength Epoxy-Based Adhesive for Fiber Reinforced Polymer Systems

In modern structural strengthening technologies, carbon fiber reinforced systems (CFRP) provide high-performance solutions. The effectiveness of these systems depends on the quality of adhesion between the fiber material and the concrete surface.

FİXA REPOX 405 has been developed as a high-strength, epoxy-based, two-component, solvent-free CARBOFİX system adhesive and impregnation resin.


Product Description

FİXA REPOX 405 is a high-adhesion epoxy resin-based adhesive specially formulated for CARBOFİX Fiber Reinforced Polymer Strengthening Systems.

Its two-component structure ensures a homogeneous mixture, while its oxide red color makes surface control easier during application.

With its high mechanical strength and chemical resistance, it ensures perfect bonding of carbon fiber fabrics to surfaces. It can be used both as an impregnation resin and as an adhesive.


Application Areas

FİXA REPOX 405 can be used in indoor and outdoor applications and is fully compatible with CARBOFİX carbon fiber strengthening systems.

Main application areas:

  • Interior and exterior applications
  • Structures to be strengthened with CARBOFİX systems
  • Bonding carbon fiber fabrics to surfaces
  • Impregnation resin for reinforced concrete strengthening
  • Structural repair and strengthening applications requiring high adhesion
  • Use as a high-strength epoxy adhesive

The product provides excellent bond strength on concrete, steel, and stone surfaces, ensuring safe and long-lasting load transfer.

  • Oxide red color: Makes application control easier.
  • Fully compatible with CARBOFİX systems: Provides maximum performance.
  • Suitable for indoor and outdoor applications.
  • CE certified quality assurance.

Application Method

Surface Preparation

  • The surface must be dry, clean, and structurally sound.
  • Oil, dust, paint residues, and loose particles must be completely removed.

Mixing

  • Components A and B are mixed according to the specified ratios using a low-speed mixer until a homogeneous mixture is achieved.
  • The mixture should be free of air bubbles.

Application

As an Adhesive:

  • Applied to the surface using a spatula or trowel.

As an Impregnation Resin:

  • Carbon fiber fabric is saturated with the resin and pressed onto the surface.

Curing

  • The applied surface should be protected from impact and moisture for 24 hours.
  • Full mechanical strength is achieved after 7 days.

Limitations and Important Considerations

  • Application temperature should not be below +10°C.
  • There must be no free water on the surface.
  • The product must be applied within its pot life period.
  • During curing, the surface must be protected from direct sunlight, rain, and frost.

Conclusion: Superior Bonding Performance in Structural Strengthening Applications

FİXA REPOX 405 is a high-adhesion, solvent-free, and long-lasting epoxy adhesive developed for CARBOFİX carbon fiber strengthening systems.

With its high mechanical performance, oxide red color, and thixotropic structure, it provides safe and controlled application on vertical surfaces. It is an ideal solution for maximum safety and performance in reinforced concrete strengthening projects.
