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 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.
