Surface preparation

Cleanliness

• Remove oil, grease and other contaminants by suitable detergent cleaning.
• Remove salts, detergents and other contaminants by high pressure fresh water cleaning.

New build:

• Remove damaged shopprimer and any contamination prior to painting.
• Abrasive blasting to min. Sa 2½ (ISO 8501-1) / SP 10 (SSPC).
• Remove dust, blast media and loose materials.

Maintenance and Repair

• Spot abrasive blasting to min. PSa 2 (ISO 8501-2) / SP 6 (SSPC).
• Minor areas can be cleaned by power tool to St 3 provided the surface is roughened and not polished.
• Remove dust, blast media and loose materials.

Roughness

• Surface profile Medium (G) (ISO 8503-2).

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

Pot life

Product temperature	Pot life	Pot life (spray)
20°C [68°F]	90 min	90 min

---

Application method

Tool	Thinning max vol.	Application parameters
Airless spray	10%	Nozzle pressure: 250 bar [3600 psi], Nozzle orifice: 0.018–0.021″
Air spray	35%	Not Applicable
Brush	10%	Not Applicable

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C [68°F].

Film thickness

Specification range	Dry film thickness	Wet film thickness	Theoretical spreading rate
Low	80 micron [3.2 mils]	123 micron [4.9 mils]	8.1 m²/L [330 sq ft/US gal]
High	125 micron [5.0 mils]	192 micron [7.7 mils]	5.2 m²/L [212 sq ft/US gal]
Recommended	80 micron [3.2 mils]	123 micron [4.9 mils]	8.1 m²/L [330 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. For best performance, avoid excessive film thickness. Overthickness must be closely controlled and never locally exceed 250 micron [10 mils] DFT. On irregular surfaces it is recommended to employ special care in avoiding over application.

---

Application conditions

• Surface temperature must be above 0°C [32°F] during application and curing.
• Temperature of product must be above 15°C [59°F] during application.

---

Drying and overcoating

Product compatibility

• Previous coat: None or according to Hempel’s specification. Recommended products are: Hempadur Fast Dry 17410, Hempadur Zinc 17360
• Subsequent coat: None or according to Hempel’s specification. Recommended products are: Hempathane

Drying time

Surface temperature	Touch dry min	Hard dry min
20°C [68°F]	60 min	120 min

Determined for dry film thickness 80 micron [3.2 mils] at standard conditions, see Hempel’s Explanatory Notes for details.

Overcoating
Hempel’s specification supersedes any guidelines indicated in the overcoating table.

Quality name	0°C [32°F]	10°C [50°F]	20°C [68°F]
Atmospheric medium
Hempadur Fast Dry 45410	Min 9 h / Max 90 d	Min 4 h / Max 60 d	Min 2 h / Max 30 d
Hempathane HS 55610	Min 9 h / Max 90 d	Min 4 h / Max 60 d	Min 2 h / Max 30 d

Overcoating times are indicative for products of the same generic chemistry. Consult Hempel’s specification for more information.

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.
• The surface must be clean before overcoating.

Other remarks

• Epoxy coats have an inherent tendency of chalking in outdoor exposure. This does not affect the performance of the coating.
• Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.

Storage

Shelf life

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

Carbon Footprint

Dry film thickness	1 µm	1 mil
GWP	8.8 g CO₂e/m²	0.046 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.
