Application method

Tool	Application parameters
Airless spray	Nozzle pressure: 150 bar [2200 psi]
	Nozzle orifice: 0.017-0.019″
Electrostatic	Nozzle pressure: 150 bar [2200 psi]
	Nozzle orifice: 0.017-0.019″

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness.

Film thickness

Specification range	Low	High	Recommended
Dry film thickness	40 micron [1.6 mils]	80 micron [3.2 mils]	50 micron [2.0 mils]
Wet film thickness	82 micron [3.3 mils]	163 micron [6.5 mils]	102 micron [4.1 mils]
Theoretical spreading rate	12 m²/L [489 sq ft/US gal]	6.1 m²/L [249 sq ft/US gal]	10 m²/L [407 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.
• Beware of ice on the surface at low temperatures.
• The film formation may be adversely affected by light rain, high humidity and/or condensation during application and the following interval after application: “8 hours, 20°C/68°F”.

---

Application remarks

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

---
