Nozzle pressure: 15 MPa
Nozzle orifice size: 0.43–0.69 mm. If brush or roller application is used, multiple coats are required to achieve the dry film thickness specified. Spray parameters are indicative and may be adjusted to site conditions. Pressure values apply to material at 20°C. (*Consult a company representative if other application methods are required!).

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. Over-thickness shall be strictly controlled; locally it shall never exceed 150 µm [6.0 mil] DFT. On irregular surfaces, particular care is recommended to avoid over-application.

Measured at 80 µm dry film thickness under standard conditions; see Hempel's explanatory notes.
- To achieve the stated drying times, adequate ventilation during application, drying and curing is essential.
| Ambient temperature | 25°C |
| Binder | 12 months |
| Curing agent | 36 months |
When stored in unopened original containers, shelf life is counted from the date of production. Thereafter, the product quality must be re-inspected. Storage at high temperatures may shorten the shelf life. For advice, consult Hempel.
- Store the product in accordance with the Safety Data Sheet, label and local regulations. Keep containers in a dry, cool, well-ventilated place away from heat and sources of ignition. Keep containers tightly closed. Handle with care.
