- Application
Mixing ratio : Stir well before use.
Thinner : No thinning
Cleaner : Hempel's Thinner 08080Tool Thinning max vol. Application parameters Nozzle pressure: 100 bar [1500 psi]
Airless spray No thinning Nozzle orifice: 0.017"
Air spray No thinning Not Applicable. Brush No thinning Not Applicable. If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray application is recommended to achieve a good surface finish. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C [68°F].
