IMPROVED METHOD FOR DRYINT COATING,FILMS AND OTHERS

A process of drying or curing coatings and films of paints, lacquers, varnishes, printing vehicles and inks. A substrate is coated in any appropriate manner by a vehicle such as a one-or two-component paint and exposed to a drying or curing agent which is deposited electrostatically on the coated ve...

Beschreibung
Zusammenfassung:	A process of drying or curing coatings and films of paints, lacquers, varnishes, printing vehicles and inks. A substrate is coated in any appropriate manner by a vehicle such as a one-or two-component paint and exposed to a drying or curing agent which is deposited electrostatically on the coated vehicle. The steps of coating the substrate with the vehicle and deposition of the drying agent are performed either simultaneously or sequentially. Apparatus includes an electrostatic spray gun (21) with a barrel (22) and a concentrically located shroud (25) ensuring the atomised drying agent is not emitted before the tip (26) of the barrel is reached.
