Application

L-3529 can be used as a sole vehicle or blended with acrylic emulsions for spray or rotogravure applications.  It may be thickened with associative thickeners for knife-over-roll or similar methods.

Drying

L-3529 may be air dried, if desired, depending on film thickness. Typical drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
