Pot life

Product temperature	Pot life
20°C [68°F]	2½ hours

Application method

Tool	Application parameters
Airless spray	Nozzle pressure: 140 bar [2000 psi]
	Nozzle orifice: 0.017-0.019″
Air spray	Not Applicable.
Brush	Not Applicable.

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Hempel’s Brush & Roller Agent 99140 can be used to improve levelling. Consult Hempel for advice. 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	55 micron [2.2 mils]	84 micron [3.4 mils]	12 m²/L [489 sq ft/US gal]
High	80 micron [3.2 mils]	123 micron [4.9 mils]	8.1 m²/L [330 sq ft/US gal]
Recommended	60 micron [2.4 mils]	92 micron [3.7 mils]	11 m²/L [448 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.

---

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 -10°C [14°F] during application and curing.
• Provide adequate ventilation during application and drying.

Relative Humidity:

• Relative humidity must be below 85% during application.
• Relative humidity must be below 85% during curing.

---

Application remarks

• Two coats of the topcoat may be necessary to obtain full hiding power.

---

Drying and overcoating

Product compatibility

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

Drying time

Surface temperature	Surface dry hours	Through dry hours	Fully cured days
20°C [68°F]	2½	8	7

Determined for dry film thickness 60 micron [2.4 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	10°C [50°F]	20°C [68°F]	30°C [86°F]	40°C [104°F]
Hempathane Topcoat 55190	Min 15 h	Min 10 h	Min 5 h	Min 2½ h
	Max Ext*	Max Ext*	Max Ext*	Max Ext*

*Ext: Depending on the actual exposure conditions, the coated surface is overcoatable for an extended period of time. Contact your local Hempel representative for advice.

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.
• Condensation on the freshly applied coating should be avoided.

---

Overcoating details

• The surface must be clean before overcoating.
• For cosmetic reasons, an extra layer of the topcoat may be applied.
• Two coats of the topcoat may be necessary to obtain full hiding power.
• If the maximum overcoating interval between epoxy and topcoat is exceeded, apply an additional thin layer of the epoxy.

---

Other remarks

• 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	24 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

• Must be stored under absolutely dry conditions, protect against seeping humidity.

Carbon Footprint

Dry film thickness	GWP (Global Warming Potential)
1 µm / 1 mil	7.7 g CO₂e/m² / 0.04 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.
