Features

Knife-blade fitted into slots in the end section allows vertical adjustment of the blade.
Two finely-made micrometer barrels that can be easily set so that gate clearances can be adjusted from 0-6.35mm in increments of 1 mil with resolution to ½ mil.
Thimbles & barrels of the micrometers are dull chrome.
Two types of side plates available that provide large paint well:
- Standard side plates are made from special clear anodized aluminum
- Tefcrom side plates are Teflon coated for lowest coefficients of friction against any solid. They are non-reactive and are great for films cast on thin substrates as it helps prevent tearing by minimizing friction with the substrate.
The ends of the side plates also serve as ergonomic operator hand grips when drawing down wet films.
Two types of blades are available:
- The standard blade is finely machined 400 series stainless steel.
- The Teflon blade is coated with a tough, durable PTFE film that provides excellent non-stick properties which makes for easy cleaning and good corrosion resistance. It also makes the blade more durable with exceptionally good abrasion resistance.
Rare earth magnets hold blade firmly in place. (The 2" applicator does not utilize the rare earth magnets and only uses one non rotating spindle micrometer that is fixed to the blade via two set screws.)
Casting knife film applicator with patented magnetic blade attachment for easy cleaning - US Patent 7,930,991.
No springs to break, rust or get clogged.
Extreme Accuracy.
Ergonomic design facilitates fast and accurate drawdowns.

More Information

Micron Measurement - Used on the Metric Microm film applicator, each graduation on the Thimble Scale is 0.01 mm, the first visible number is 5 which is 5 graduations = 0.05 mm = 50 microns. One complete revolution is 50 graduations which is 0.50mm = 500 microns. The first increment on the Sleeve Scale is .50 mm = 500 micron, the second increment on the Sleeve Scale is 1 mm = 1000 microns, etc.

Procedure

Place applicator at upper end of test panel.
Pour coating directly in front of the knife-blade.
Draw applicator toward lower end of panel at an approximate uniform rate of 10 to 12 inches (250-300mm) per second.
Clean applicator immediately after use and thoroughly dry the blade. Caution: Do not wet or submerse micrometer heads.

Step-by-Step Zero Adjustment Instructions:

Prepare the Surface:
Use a polished granite flat plate or a suitable plate-glass surface for calibration.
Set Micrometers to Zero:
- Ensure the blade contacts the flat plate fully from end to end.
- Confirm no side plate elevation.
Visual Inspection:
- Place the applicator between a bright light and the observer.
- Ensure no light is visible beneath the blade and side plates.
Zero Check Tolerance:
- Verify the zero point is within ±0.0005".
- If outside this range, proceed with adjustments.
Adjust the Micrometers:
- Apply slight, consistent pressure on the applicator's support rods.
- Rotate micrometers until the blade sits evenly on the flat plate.
- Loosen the micrometer thimble's set screw.
- Align the thimble's zero mark with the barrel's zero mark.
- Tighten the set screw to secure the setting.
Recheck Zero Point:
- Repeat adjustments if necessary to achieve accurate calibration.
