FİXA REPOX 400H: Moisture-Tolerant Epoxy-Based Fiber Reinforced Polymer System Adhesive
Structural strengthening applications using carbon fiber systems require high adhesion strength and resistance to environmental conditions. Maintaining adhesion performance in humid environments is critical for the safe operation and durability of the system.
FİXA REPOX 400H is a specially developed, epoxy-based, two-component, solvent-free, thixotropic, and moisture-tolerant adhesive and impregnation resin for the CARBOFİX Fiber Reinforced Polymer Strengthening Systems.
Product Description
FİXA REPOX 400H is a high-performance epoxy adhesive specially formulated for CARBOFİX Fiber Reinforced Polymer Systems.
Thanks to its oxide yellow color and moisture tolerance, it provides excellent adhesion even on damp or slightly humid surfaces.
Its two-component structure ensures a homogeneous mixture, while its thixotropic consistency allows easy application on vertical surfaces without sagging.
Application Areas
REPOX 400H is especially suitable for carbon fiber applications on damp surfaces. Its application areas include:
-
Interior and exterior applications
-
Structures to be strengthened with CARBOFİX systems
-
Bonding carbon fiber fabrics to damp surfaces
-
Strengthening reinforced concrete structural elements
-
Use as an impregnation resin on concrete surfaces
-
Structural repairs requiring high adhesion and moisture tolerance
With its high bond strength and chemical resistance, the product provides long-lasting performance in both new construction and strengthening projects.

Application Method
Surface Preparation
-
Concrete surfaces must be clean, sound, and as dry as possible.
-
Application is possible on slightly damp surfaces; however, there must be no standing water.
Mixing
-
Components A and B should be mixed according to the specified ratios.
-
A low-speed mixer should be used to achieve a homogeneous mixture.
Application
Bonding Application:
-
Applied using a spatula or trowel.
Impregnation Resin Application:
-
Carbon fiber fabric is saturated with the resin and then pressed onto the surface for installation.
Curing
-
The applied area should be protected against impact and moisture condensation for 24 hours.
-
Full mechanical strength is achieved after 7 days.
Limitations and Important Considerations
-
There must be no free water on the surface.
-
Application temperature should not be below +10°C.
-
A new mixture should be prepared when the pot life period has expired.
-
Protect from direct water, rain, and frost during curing.
