Application

LWU7020NC Primer was designed to be used as a wipe on primer. Shake container to mix contents prior to application. Dip a clean, lint free, dry towel into a container of LWU7020NC and wipe onto the substrate to be printed. Cover the entire substrate with primer making sure to get a uniform deposit across the substrate.

Processing

• Allow the primer to dry thoroughly. (Approx. 10 minutes depending on humidity levels).
• Print the newly primed surface as soon as possible. The primed surface may be printable for up to 24 hours after application of the primer, possibly less in very humid environments.
