| Shelf Life | Base component 6 months from date of manufacture, Hempel's Zinc Metal Pigment 3 years (stored in sealed containers at 25 °C). The shelf life depends |
|---|
on the storage temperature; when the storage temperature is above 25 °C, the shelf life is shortened. Do not store above 40 °C. Gelling of the liquid or formation of a gel after mixing indicates that the shelf life has been exceeded.
| Mixing ratio | Liquid 15798 : Hempel's Zinc Metal Pigment 97170 = 1 : 1 (by weight) (see notes for ratio by volume) |
|---|---|
| Recommended method | Brush (*consult our company representative if other application methods are required!) |
| Nozzle pressure | 10.0 MPa (airless spray data for reference only; may be adjusted in practice.) |
| Safety | Handle this product with care. Before and during use, observe all safety labels on the packaging and cans, and refer to our company's material |
safety instructions and comply with relevant national or local government safety regulations.

environment) and below, and where no special service life requirements apply, a surface preparation grade of SSPC-SP6 is sufficient.
| Application conditions | The surface to be coated must be completely clean and dry, and its temperature must be above the dew point to prevent condensation. Temperature range 0 °C–40 °C; curing requires a minimum |
|---|
relative humidity of 65%; curing is very slow at low temperature and low humidity. Refer to the application instructions for this product.
| Additional coat | Apply subsequent coats according to the coating system specification. Recoating is expected to be carried out within 6 months after application. |
|---|---|
| Notes | Note: if used for corrosion protection of high-temperature insulated equipment, particular attention must be paid to preventing moisture vapour penetration during shutdown periods, so as to avoid temperature rise |
Climate/service temperature: when overcoated with Hempel's Silicone Aluminium Paint 56913/56914, this product can be used under high-temperature conditions. In this case it can permanently withstand a dry temperature of 500 °C. To avoid use under regular high/low temperature cycling conditions, the recommended maximum service temperature is Without stirring: if mixing by volume ratio, proceed as follows: weigh 8.5 parts by volume of the base, then add Hempel's Zinc Metal Pigment until Film thickness: in a heavy-duty system with a topcoat, the recommended dry film thickness is 50–80 µm (wet film thickness 75–125 µm); for systems without a topcoat that require long-term protection, the recommended film thickness is 75 µm (wet film 100–125 µm).
When used at high temperatures, the dry film thickness must not exceed 40–50 µm to avoid cracking, particularly where the ambient service temperature changes abruptly.
(The dry film thickness range does not take into account the corrosion factors caused by surface roughness listed in ISO19840.).
Thinning: Hempel's Thinner 0870M accelerates curing.
Relative humidity above 50%: 0870M (max. 30%), curing time: 8 h at 20 °C.
Relative humidity below 50%: 0870M (max. 30%), curing time: 20 h at 20 °C
