The adhesion strength of paint and surface coatings is crucial for the material to fulfil its protective and decorative function. Testing the strength of surface coatings in the paint and coating industry is essential to ensure product quality and durability.

Adhesion strength testing is required in accordance with standards ISO 4624, ISO 2409 (cross-cut test) and ASTM D4541, and forms an important part of surface coating quality control before a product is placed on the market.

Adhesion Strength Measurement Methods

Pull-off test – attaches a test dolly to the surface and pulls it off with a measured force; provides an accurate numerical value in units of N/mm² or MPa (ISO 4624, ASTM D4541)
Cross-cut test – cuts a grid into the coating layer and visually assesses flaking on a scale of 0–5 (ISO 2409)
X-cut test – used for thin coatings (ASTM D3359)

Elcometer Adhesion Strength Testers

The Elcometer 108 and 510 pull-off adhesion testers are the world's leading solutions for measuring adhesion strength in both production and laboratory conditions. The hydraulic pull mechanism ensures a consistent and accurate pull force, eliminating user errors. Results are recorded in the ElcoMaster application.

Common questions about this product.

Frequently asked questions

Which standards are supported for adhesion strength testing?

Adhesion strength testing is required according to standards ISO 4624, ISO 2409 (cross-cut test) and ASTM D4541. For the X-cut test, ASTM D3359 is used.

Which method provides an accurate numerical adhesion strength value?

The pull-off test attaches a test dolly to the surface and pulls it off, providing a precise numerical value in units of N/mm² or MPa (ISO 4624, ASTM D4541).

Which method should be used for testing thin coatings?

For thin coatings, the X-cut test (ASTM D3359) is used.

How is the result evaluated in a cross-section test?

The cross-cut test cuts a grid into the coating, and the peeling is assessed visually on a scale of 0–5 (ISO 2409).

Which Elcometer devices are suitable for adhesion strength measurement and how are the results managed?

The Elcometer 108 and 510 pull-off adhesion testers are suitable for both production and laboratory environments; the hydraulic pull mechanism ensures a uniform and precise pull-off force, and the results are recorded in the ElcoMaster application.
