Application conditions

• To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C [5°F] above the dew point.
• Surface temperature must be above 5°C [41°F] during application and curing.
• Optimal paint temperature for proper mixing, pumping and spraying is: 15-25°C [59-77°F].

Relative Humidity:

• Relative humidity must be below 80% during application.
• Relative humidity must be below 80% during curing.

Drying and overcoating

Product compatibility

• Previous coat: None.
• Subsequent coat: According to Hempel’s Specification.

Drying time

Surface temperature	Touch dry	Hard dry
20°C [68°F]	min 60	hours 3½

Determined for dry film thickness 40 micron [1.6 mils] at standard conditions, see Hempel’s Explanatory Notes for details.

Overcoating

Quality name	20°C [68°F]
Atmospheric medium	Min 8 h / Max 30 d
Immersion	Min 8 h / Max 30 d

Overcoating times are indicative for products of the same generic chemistry.
Hempel’s specification supersedes any guidelines indicated in the overcoating table.

Drying conditions

• To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.

Overcoating details

• If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
• Remove zinc salts or other contamination before overcoating.

Storage

Shelf life

Ambient temperature	Base	Curing Agent
25°C [77°F]	12 months	36 months

Shelf life from date of production, when stored in original, unopened containers.
Thereafter, the product quality must be re-inspected. Storage at elevated temperatures may reduce shelf life.
For advice, please consult Hempel.

Storage conditions

• Product must be stored according to local legislation, at maximum 40°C [104°F], without direct sunlight and protected from rain and snow.

Carbon Footprint

Dry film thickness	GWP (Global Warming Potential)
1 µm	14.5 g CO₂e/m²
1 mil	0.075 lb CO₂e/ft²

The carbon footprint is for 1 square meter / square foot of surface area with a dry film thickness of 1 micron / mil.
The scope includes raw materials, in-bound transport to the Hempel factory, Hempel manufacturing processes, and any Volatile Organic Compounds emitted during and after the application of the product.
It is calculated based on the standard shade defined in this PDS. Values may vary with shade.
