Application

Mixing ratio
Stir well before use.

Thinner

Application method

Tool	Thinning max vol.	Application parameters
Airless spray	5%	Nozzle pressure: 150 bar [2200 psi]
		Nozzle orifice: 0.018″
Air spray	15%	Not Applicable.
Brush/Roller	5%	Not Applicable.

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. To comply with Korean VOC regulation, thinning is limited to max. vol. 1%. 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	25 micron [1.0 mils]	54 micron [2.2 mils]	19 m²/L [774 sq ft/US gal]
High	40 micron [1.6 mils]	86 micron [3.5 mils]	12 m²/L [489 sq ft/US gal]
Recommended	30 micron [1.2 mils]	65 micron [2.6 mils]	15 m²/L [611 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 [50°F] during application and curing.

---

Application remarks

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

---

Drying and overcoating

Product compatibility

• Previous coat: Recommended product is: Hempalin primer 12050, Hempalin Primer HI-Build 13200, Hempalin Undercoat 42460
• Subsequent coat: None.

Drying time

Surface temperature	Touch dry hours	Hard dry hours
10°C [50°F]	6	14
20°C [68°F]	2	4
30°C [86°F]	1	2
40°C [104°F]	½	1½

Determined for dry film thickness 30 micron [1.2 mils] at standard conditions, see Hempel’s Explanatory Notes for details. The natural tendency of Alkyds to discolour is also reflected in this product. Discoloration can be accelerated by inadequate ventilation, exposure to chemicals, elevated temperatures and low light conditions.

---

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]
Hempalin Enamel 52140	Min: 16 h	8 h	6 h	4 h
	Max: 9 d	5 d	4 d	60 h

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 dry and clean prior to application.

---

Other remarks

• Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.

Storage

Shelf life

Ambient temperature	Product
25°C [77°F]	60 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	9.8 g CO₂e/m² / 0.051 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.
