Product Description
FOX EPOFLOW® FC541 is an epoxy-based, three-component (A: Epoxy Resin, B: Epoxy Hardener, C: Specially Graded Quartz), solvent-free structural repair and filling mortar. It is evaluated within the scope of Bayındırlık Poz No: 04.613/8-b and complies with EN 1504-3 standard class R4. The product delivers high mechanical performance with compressive strength of >40 N/mm² at 1 day and >70 N/mm² at 7 days. Adhesion strength to concrete is >2 N/mm² and to steel >2,5 N/mm². With an application thickness range of 4 mm to 50 mm, it can close wide repair sections in a single coat. Applied at substrate temperatures between +5°C and +35°C; withstands service temperatures from -15°C to +70°C. Solvent-free and hardens without shrinkage.
Key Benefits
- Thanks to EN 1504-3/R4 compliance, it can be confidently specified in structural repair projects.
- Its solvent-free formulation enables safer application in enclosed and poorly ventilated areas.
- Provides permanent and reliable adhesion with >2 N/mm² bond strength to concrete and >2,5 N/mm² to steel.
- With >70 N/mm² compressive strength at 7 days, it delivers long-lasting repairs on high load-bearing structural elements.
- Direct application without a primer shortens the work process and reduces costs.
- A single-coat application thickness range of 4–50 mm offers the flexibility to repair damage of varying depths in a single operation.
Advantages
- Applied without primer.
- Resistant to chemicals.
- High compressive, flexural and tensile strength.
- High abrasion and impact resistance.
- Long pot life and working time.
- Solvent-free.
- Hardens without shrinkage.
Usage Areas
- Repair of reinforced concrete structural elements
- Repair of marine structures
- Repair of underground civil engineering structures
- High-strength assembly and repair work on crane beams and supports
- Filling of gaps between reinforced concrete columns and steel reinforcement
Application Steps
- 1
Surface Preparation
Surfaces to be repaired must be sound, dry, load-bearing, dust-free and clean. All oil, grease, rust and paraffin residues that could weaken surface adhesion must be thoroughly removed. The edges of the broken surface should be made as vertical as possible, and rust and residues on the reinforcement must be cleaned.
- 2
Mixing
Components A and B are added to a clean mixing bucket and mixed for 2 minutes using an electric mixer at 400–600 rpm with a suitable mixing paddle. Component C is then added slowly and mixed until a homogeneous, lump-free mixture is obtained.
- 3
Application
The prepared mixture should be applied to the surface with a trowel. The thickness should be between 4 mm and 50 mm. The maximum application thickness must not exceed 50 mm in a single coat.

Tool Cleaning
Tools and equipment used must be cleaned immediately with solvent after application. Once FOX EPOFLOW FC541 has cured, it can only be removed from the surface mechanically.
FOX EPOFLOW FC541 must not be applied at temperatures below +5°C or above +35°C.
At +20°C it must be applied within 30 minutes, and at +30°C within 20 minutes; once the working time is exceeded, the material becomes unusable.
For the material to complete its cure, the substrate and ambient temperature must not fall below the permitted minimum temperature.
No solvents or similar substances must be added to the prepared mix during application.
Large open surfaces exposed to the atmosphere must be protected from rain and external influences for 24–48 hours after application.
Tools and equipment must be cleaned with solvent immediately after application. Cured product can only be removed by mechanical means.
Opened packages must be resealed and consumed within 1 week.
The product must be stored between +5°C and +30°C, in a cool and dry place away from direct sunlight. Protect from frost.
Approaching storage and application areas with open flames is dangerous; these areas must be ventilated.
Work clothing, protective gloves, goggles and a mask must be worn during application. Avoid contact with skin and eyes; in case of contact, wash thoroughly with plenty of water and soap. If swallowed, consult a doctor immediately.
Food and beverages must not be brought into application areas. Store out of reach of children.
Working and reaction times of epoxy-based repair mortars are affected by air temperature, humidity and substrate temperature. High temperatures shorten the working time; low temperatures extend it.
Technical property values are given for +23°C and 50% relative humidity conditions.
