Trade Sales (“U”- Shape) Applicators
Each of these instruments has a 6 mil and an 8 mil gap clearance, laying down wet film thicknesses of approximately 3 and 4 mils, respectively. These are the thicknesses most often recommended for the testing of solventborne and waterborne architectural coatings, hence their characterization by Leneta as “Trade Sales” applicators. The film widths of 4 and 6 inches take advantage of the most popular Leneta test chart widths of 5-1/2 and 7-5/8 inches. Their “U”-shape structure retains a substantial volume of test coating to assure completeness of drawdowns.
