Description
Demco® EPOX 540 is a two-component, solvent-free, epoxy-based resin used for the lamination of wood and composite materials.
Advantages
- Consolidates wood and gives it elasticity.
- High bond strength.
- Penetrates deeply.
- Once cured, it is unaffected by water and is waterproof.
- Resistant to solvents and many chemicals.
Application Areas
Used for strengthening, repairing and protecting wooden and composite boats by fiber lamination.

Surface Preparation and Application
Surface Quality: All surfaces must be sound, dry and of sufficient strength.
Surface Preparation: The surface must be free of dust, rust, oil, salt and similar contaminants. All surfaces must be sanded and primed with Demco® EPOX 540.
Mixing: Demco® EPOX 540 is supplied in ready-to-use sets. When preparing the mix, pour the entire B component into the A component and mix for at least 3 minutes with a low-speed mixer and a suitable mixing paddle. No unmixed material should remain on the sides or bottom of the container, and care must be taken to prevent air bubbles from forming during mixing.
Application: Surfaces to be coated must be dried and free of contaminants such as oil and dust. The components are mixed with a suitable mixer so that no air is entrapped. For lamination, the product is applied to the surfaces with a roller or brush and spread out. The fibers must be thoroughly wetted out and saturated with resin, then rolled so that no air bubbles remain.
Application Conditions
- During application, the surface and ambient temperatures must be within 10 °C – 30 °C.
- Do not add solvents or similar thinning agents to the mix.
- Prepare only as much material as can be used within the working time, and continue working until it has all been used.
- Mixing must be carried out with suitable mechanical mixers. Do not mix by hand.
- After application, protect from moisture, condensation and water for at least 24 hours.
