The solution is spread lightly over one square inch of the test material.&nbsp; If the wetting solution stays intact for two seconds, the treat level is at least as high as the dyne level of that solution. Repeat the procedure until a solution is used that will bead up on the surface of the material being tested. The film treat level would be identified as the last solution level that remains wetted out for 2 seconds on the surface. (A clean cotton applicator must be used for each dyne solution to avoid contamination that may distort the results.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To learn more, view our technical paper:&nbsp;<a href=\"\/web-treating\/library-resource\/buddy-can-you-spare-a-dyne\/\">Buddy, Can You Spare a Dyne?<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"featured_media":1869,"parent":0,"menu_order":0,"template":"","resource_type":[20],"resource_application":[31,28,44,29,30,25],"technology":[32,34,35,33],"application_subcategory":[39],"class_list":["post-1866","resources","type-resources","status-publish","has-post-thumbnail","hentry","resource_type-video","resource_application-battery-manufacturing","resource_application-coating-laminating","resource_application-extrusion-coating","resource_application-film-extrusion","resource_application-narrow-web","resource_application-printing","technology-corona","technology-flame","technology-ozone","technology-plasma","application_subcategory-surface-energy"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 -
