Application and Curing Notes
The surface must be dry and free of dirt, grease, and oil before application. The manufacturer's instructions state that an even, lightly applied coating typically provides the desired resistivity. Allow 24 hours full drying at room temperature (70°F/21°C) for full cure; faster curing can be achieved by oven treatment at 120°–150°F for 1–2 hours. Please note that heavy application or application in high relative humidity may result in haziness of the layer.
