"Cross Hatch" Coating Adhesion Test

Adhesion Test ARW

Compact instrument with ergonomic handle with a simple and quick coupling system of the cutting blade, no additional key needed. Complies with ASTM D3359 - ISO 2409 standards.

8 POSITIONS BLADE BLOCK: Equipped with 8 blade positions, this means the possibility, once the cutting edges are worn out, to rotate the blade block in 8 different positions offering a longer life than models with single blade or 2/4/6 blade positions. (duration equal to 8 times the single blade version)

Three different models to choose from based on the thickness of the coating, 1, 2 or 3 mm blade space:

• 220122702 KIT ARW-502/3A 0÷60µm (1mm blade space)
• 220122703 KIT ARW-502/5A 2 60÷120µm (2mm blade space)
• 220122704 KIT ARW-502/6A 120÷250µm (3mm blade space)

Cross Hatch Test ISO 2409

This method specifies a procedure for determining the resistance of paints and coatings to separation from substrates when a cross-grain is made at right angles across the paint all the way to the substrate.
The method can be used for a pass/fail test. In the case of multilayer systems it is possible to determine the adhesion between the different layers.

Test method

• Make a cross incision on the coating until it reaches the substrate, a checkerboard will be created made up of small squares of 1, 2 or 3mm size, depending on the model used.
• Brush diagonally 5 times each, using a brush, or apply suitable tape to the cutout and remove
• Observe the grating area using a magnifying glass verifying the degree of adhesion according to ISO2409
