Primer 540
Hempel Epoxy Graphene Zinc-rich Primer 540 is a two-component, graphene-reinforced activated zinc-rich primer that effectively combines the company's advanced Activator technology with graphene technology. After curing, it forms a hard and corrosion-resistant coating. Complies with the requirements of HG/T 5573-2019—Type II coatings.
As a general-purpose long-life zinc-rich primer, it is used on steel under moderate to severe corrosive environments, as a primer in combination with other coatings. Suitable for steel structures in high to corrosive environments ISO 12944 C5-High, such as refineries, power stations, bridges and buildings.
- Under cyclic temperature, good flexibility and self-repair of micro-cracks improve cracking resistance.

- Before final painting, all shop primer breakdown and contamination incurred during storage and erection must be thoroughly cleaned by mechanical/chemical means.
- The maximum permitted water-soluble salt level tested in accordance with ISO 8502-9 is 50 mg/m² (as NaCl).
- Use high-pressure fresh water washing (approx. 30 MPa [4400 psi]) combined with scrubbing to remove zinc salt deposits and white rust.

If brush or roller application is used, multiple coats are required to obtain the specified dry film thickness. At low paint temperatures, additional thinning may be required, which will result in lower film build and slower drying. Keep thinning to a minimum. Spray parameters are indicative and may be adjusted according to site conditions. Pressure values apply to material at 20°C. (*For other application methods, consult the company representative!).
| Specification range | Low | High | Recommended |
| Dry Film Thickness | 50 µm | 100 µm | 60 µm |
| Wet Film Thickness | 81 µm | 161 µm | 97 µm |
| Theoretical Spreading Rate | 12 m²/L | 6.2 m²/L | 10 m²/L |
Depending on the application and area of use, the product may be specified at a film thickness different from that indicated. This changes the spreading rate, drying and curing times and overcoating intervals. Actual consumption factors may vary with application conditions, equipment and workmanship.
- Ideal spray performance is obtained at paint temperatures of 15–30 °C [59–86 °F]; outside this range, additional thinning may be required.
- Additional thinning may be required at low paint temperatures, resulting in lower film build and slower drying.
- If brush or roller application is used, more coats are required to achieve the specified dry film thickness.
