TQC CC1000 Cross-Cut Paint Adhesion Tester

Cross Hatch Adhesion Testing indicates whether coating adhesion is adequate. ASTM D3359 specifies methods for testing coating adhesion on metal surfaces, whereas ISO / DIN 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 CC1000 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 ISO / DIN 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.

The TQC CC1000 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 CC1000 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]



Features of the TQC CC1000 Cross Hatch Adhesion Tester include:

  • Self-adjusting knife-holder ensures equal pressure on the cutting knife
  • Round cutting knife with eight cutting edges for longer lifetime
  • Ergonomically-shaped handle
  • Easy-to-change round cutting knife
  • Wide range of knife sizes available for different coating thicknesses and substrates, and testing according to different standards.


CC1000 Cross-Hatch Cutter kits include a soft grip handle, a hardened steel cutter (user selected), a nylon brush, an illuminated magnifier, adhesive tape (select ISO or ASTM standard) and one 4 mm Allen key.

Cutters or knives can also be purchased separately.

The following is provided as a reference for proper knife selection: 

ISO 2409 - Paints and Varnishes -- Cross-cut Test -

specifies:        1 mm. spacing for coatings up to 60 µm on hard substrates
                     2 mm. spacing for coatings up to 60 µm on soft substrates
                     2 mm. spacing for coatings from 61 to 120 µm on both hard and soft substrates
                     3 mm. spacing for coatings from 121 µm to 250 µm on both hard / soft substrates

ASTM D3359 - Standard Test Methods for Measuring Adhesion by Tape Test - Method B -

specifies:        1 mm. spacing x 11 cuts for coatings < 50 µm (2.0 mils)
                     2 mm. spacing x 6 cuts for coatings from 50 to 125 µm (2.0 - 5 mils)
                     *For coatings thicker than 5 mils (125 µm) Test Method A is recommended.

[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.”
