Universal Blade Applicator

The Universal Blade Applicator provides one of the most precise and reproducible methods for applying a coating to a flat surface for further evaluation. Since most physical properties depend on the applied thickness, it is of utmost importance that not only the thickness of a coating is reproducible, but also that the correct thickness value is known. Applicator blades that have the most common contour will, on average, apply a wet coating thickness that is only half the physical clearance between the blade and the surface receiving the coating .

Characteristics:

• Simple and sturdy design single blade applicator
• Machined from the best quality aluminum alloy.
• It is sturdy in design and construction, and with reasonable care and cleaning after each use, will provide years of satisfactory service.
• The applicator blade is produced in standard lengths of 2, 4, 6, 8, 10 and 12 inches.
• All leaves are identical except for their length.
• They are two inches high, one inch wide, and have a bottom surface contour that is symmetrical and similar to "bird" blades, allowing the assembly to be operated in any direction.
• There are two different ranges of applicators available
  • clearance from 0 to 50 thousand
  • clearance from 0 to 10 thousand
• It consists of a blade and two side support plates. Each side plate is attached to the blade by a knurled head bolt. The vertical clearance of the blade relative to the bottom edges of the supporting side plates is controlled by blade elements extending over the side plates.
• The side plates, which determine the range, are identical except for the gradient of the height increase from the front to the rear of the side plate.
• For greater accuracy, only the inside edges of the side plates contact the surface to receive the test material. The side plates are higher at the rear than at the front. Therefore, as the side plate moves forward, the blade clearance increases up the scale.
• The side plates are four inches long and border 1-3/4 inches high.
• Has wedge expansion function
  • The bottom surface of the side plate is designed so that only the inner edge comes into contact with the base that receives the test material. This feature allows error-free adjustment of the applicator to produce wedge-shaped films. The unique design of the applicator provides the wedge expansion feature shown on the left. Closer inspection of any part of the test material, for example the central part of a 0 to 10 clearance film, is possible by resetting the applicator so that the entire width of the applicator covers only the range of greatest interest of, say, 4 to 6 thousandths of an inch
• The side plates and blade are manufactured as a combined assembly. Make sure the reference marks on the plates and blade match on any reassembly. Do not exchange parts between different applicators.
