Gardco Adjustable Micrometer "Microm" Film Applicator
Wet Films of Uniform Thickness Can Be Cast With the Knife-Blade Set for the Desired Gate Clearance Between 1 and 250 Mils.
The Adjustable Microm Film Applicator Consists of the Following:
A.
Two finely-made micrometer barrels that can be easily set so that gate clearances can be adjusted from 0 to 0.250" in increments of 1 mil (.001") Thimbles and barrels of the micrometers are dull chrome.
B.
A special anodized aluminum frame with two end sections that provide a large paint well. The end sections also serve as operator hand grips when drawing down wet films.
Item No. AP-M02
C.
A stainless steel knife-blade to guard against nicks and fitted into slots in the end section that allows vertical adjustment of the blade.
D.
A leaf spring attached to the top plate maintains an upward pressure of the blade against the two micrometer feet to retain gate settings of the blade.
For information on laying down wet films of coating materials, refer to ASTM Specification D 823 - Producing Films of Uniform Thickness of Paint, Varnish, Lacquer and Related Products of Test Panels.
Operation
Place applicator at upper end of test panel. Pour coating directly in front of the knife-blade. Draw applicator slowly toward lower end of panel at a uniform rate of 10 to 12 inches (250-300mm) per second. Clean applicator immediately after use. Caution: Do not wet or submerse micrometer heads.
Calibration
Before use, check the zero settings of the micrometers. Place applicator on a polished plate glass of suitable size. Set micrometers at zero. When the applicator is placed between the observer and a bright light, the blade should touch the glass from end to end without the sideplate being elevated. The zero point should check within ¡¾0.0005". If it does not, and settings are required, simply set the micrometers to zero, loosen the mike clamp set screws, press the knife-blade down on the glass plate, press down the micrometers until barrels are seated against the blade and then tighten the clamps.

Equivalent metric versions of all of the above models are available. A 6- inch applicator, for example, would become a 15.2mm path width blade, adjusting in 0.01mm increments to 13mm maximum opening. Locking Micrometers are also available at additional cost.
