RELEST Wind LEP ETU Cartridge - I374-8735 belongs to Polyurethane. RELEST Wind LEP ETU Cartridge is designed to protect the leading edge of wind turbine blades from erosion damage by airborne particles such as rain, sand, hail and dust. Used together with the Relest wind power adhesion promoter (I367-0080), good substrate adhesion is usually obtained. RELEST Wind LEP ETU Cartridge shows a good balance between corrosion resistance and application performance, in particular good levelling. Parameters on this page: volume solids >99%, theoretical spreading rate 2 m²/kg.

Surface cleaning: all surfaces to be coated shall be clean, dry and free from contamination. Oil and dirt shall be removed before painting. Use vacuum or clean, dry compressed air, and wipe with a clean, oil-free, dry cloth to remove all dust thoroughly.
Clean before abrading; otherwise grease and oil stains will become embedded in the surface, and a clean surface cannot be obtained.
EP laminate must be thoroughly abraded on the substrate to be treated to remove release agent residues from the surface.
The surface must be intact, clean and dry, free from oil, grease, dust and other contaminants.
| Mixing | The product requires the use of a static mixer. |
|---|
1. Once the cartridge is opened, the static mixer shall be fixed immediately. 2. Clamp the container in the dispensing device with the static mixer pointing up.
3. Push down to start dispensing and slowly fill the mixer.
4. Turn the dispenser so the mixer points down and discard the first 3–4 cm of discharged material.
5. The mixture shall be a uniform colour. Before the surface is smooth, any irregularities shall be corrected immediately with a metal trowel.
| Mixing ratio | Use Component B Relest hardener PUR 735 (I385-0735): 100 parts : 100 parts by volume; 100 parts : 81 parts by weight. |

| Brush | Recommended |
|---|---|
| Roller application | Recommended |
| Thinner | Do not thin |
| Cleaner | RELEST Thinner PUR 132 |
| Interruption of work | Clean all equipment thoroughly with RELEST Thinner PUR 132. Once mixed, a batch of paint shall not be re-sealed; if work is interrupted for too long, remix a fresh batch of paint. |
| Cleaning | Clean all equipment immediately after use with RELEST Thinner PUR 132. |
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
RELEST Wind LEP ETU Cartridge shows a good balance between corrosion resistance and application performance, reflected in good levelling.
The product is suitable for OEM and repair, and can be applied on horizontal and vertical substrates.
To achieve suitable adhesion on various substrates, Relest wind power adhesion promoter (I367-0080) is recommended.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
For suitable primers/intermediate coats, consult the local International Paint representative.
