Pot life

Product temperature	10°C [50°F]	20°C [68°F]
Pot life	90 min	60 min

Application method

Tool	Thinning max vol.	Application parameters
Airless spray	5%	Nozzle pressure: 175 bar [2500 psi]
		Nozzle orifice: 0.017–0.021″
Brush	5%	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	Low	High	Recommended
Dry film thickness	50 micron [2.0 mils]	80 micron [3.2 mils]	60 micron [2.4 mils]
Wet film thickness	82 micron [3.3 mils]	132 micron [5.3 mils]	99 micron [4.0 mils]
Theoretical spreading rate	12 m²/L [489 sq ft/US gal]	7.6 m²/L [310 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.
• 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”.

Relative Humidity:

• Relative humidity must be below 70% during application.
