TQC’s CC2000 Cross Cut Adhesion Tester is used to test the adhesion of dry coats of paint to their substrate in accordance with either ASTM D3359 or EN-ISO 2409. Two series of parallel cuts are made in the paint at right-angles to one another, creating a lattice pattern of either 25 or 100 same-sized squares. The test area may be brushed with a stiff brush, or a specified adhesive tape may be used to pull-test coatings on hard surfaces. Cross-cut testing assesses the general quality of coatings adhesion either to the substrate or, in a multi-layer system, of individual layers of coating to one another; it does not ‘measure’ the adhesion of the coating being tested.

Cross Hatch Adhesion Testing indicates whether coating adhesion is adequate. ASTM D3359 specifies methods for testing coating adhesion on metal surfaces, whereas EN-ISO 2409 provides a method for testing adhesion of paints and varnishes on a variety of substrates. Under either Standard, cuts are made through the coating layer at specified distances to observe whether the coating adheres to the surface. The condition of the coating in the cross-cut area is evaluated by comparing it to a classification chart with images showing the percentage of area from which coating has been removed.

The TQC CC2000 Cross Cut Paint Adhesion Tester features a rotary cutting knife fitted to comfortable, padded handle. The knife has four sets of blades with 6 or 11 teeth of specified spacing. Each blade has 2 cutting edges; simply rotate the knife in the handle for a fresh cutting edge. The replaceable cutting knives are available in 1, 2, 3, and 1.5 mm spacing, to accommodate both ISO and ASTM standards. The TQC CC2000 Cross-Cut Paint Adhesion Tester is suitable for dry film thickness of up to 250 µm on soft substrates, 125 µm on hard substrates. [1]

[1] ASTM D3359 states “Test Method B is not considered suitable for films thicker than 5 mils (125 µm), but Note 1 states “subject to agreement between the purchaser and seller, Test Method B can be used for thicker films if wider spaced cuts are employed.”
