Product characteristics

Recommended use
Hempablade Edge 171 is recommended as the final top-layer applied either during the blade factory coating application process or during field service & maintenance situations. A fast curing solution and therefore suitable when high productivity is key.

Service temperature:

• Maximum, dry exposure only: 60°C [140°F].

Features

• High performance rain erosion protection tested according to industry standard DNV-GL RP-0171.
• A broad application window extending seasonality use and application efficiency. Limits annual energy production loss and noise driven by aerodynamic disturbances.

Surface preparation

Cleanliness

• The surface must be dry and clean prior to application.

New build:

• A uniform anchoring profile should be achieved by suitable surface preparation method(s).
• Remove dust, loose material and any other contamination.
• The surface must be dry and clean prior to application.

Maintenance and Repair

• Maximum allowed concentration of water soluble salts measured according to ISO 8502-9: 110 mg/m² (NaCl equivalent).
• Remove oil, grease and other contaminants by suitable detergent cleaning.
• A uniform anchoring profile should be achieved by suitable surface preparation method(s).
• Remove dust, loose material and any other contamination.
• The surface must be dry and clean prior to application.

Consult Hempel’s separate Surface Preparation Guidelines for more details.

Film thickness

Specification range	Low	High	Recommended
Dry film thickness	150 micron [6.0 mils]	200 micron [8.0 mils]	175 micron [7.0 mils]
Wet film thickness	150 micron [6.0 mils]	200 micron [8.0 mils]	175 micron [7.0 mils]
Theoretical spreading rate	6.7 m²/L [273 sq ft/US gal]	5 m²/L [204 sq ft/US gal]	5.7 m²/L [232 sq ft/US gal]

Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. The product must be applied on top of a sound intact system.

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.
• Surface temperature must be below 35°C [95°F] during application and curing.
• According to Hempel’s Specification.

Relative Humidity:

• Relative humidity must be in the range 30-85% during application.
• Relative humidity must be in the range 30-85% during curing.

Drying and overcoating

Product compatibility

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

Drying time

Surface temperature	Touch dry (h)	Surface dry (h)	Hard dry (h)	Through dry (h)
10°C [50°F]	4	7	10	13
20°C [68°F]	3	5	7	9
30°C [86°F]	2	4	4½	9

Determined for dry film thickness 175 micron [7.0 mils] at standard conditions, see Hempel’s Explanatory Notes for details.
Any masking tape used during paint application should be removed while the paint is still in the wet condition.

Drying conditions

• Condensation on the freshly applied coating should be avoided.

Overcoating details

• The surface must be clean before overcoating.
• If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.

Storage

Shelf life

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

• The curing agent is sensitive to moisture. Store in a dry place and keep the can tightly closed until use.
• In case shelf life is exceeded, the product must be re-evaluated before use. Please contact a Hempel representative.

Carbon Footprint

Dry film thickness	1 µm	1 mil
GWP (Global Warming Potential)	6.8 g CO₂e/m²	0.035 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.
