Applied Technical Services offers coating adhesion testing to clients looking to determine the adhesive value of their coatings. Our services adhere to the American Society for Testing & Materials (ASTM) international standards. We provide multiple options for coating adhesion testing, including the following test methods:
Cross-Cut Test
Testing experts cut a lattice pattern into the coating, down to the substrate. The adhesive tape is placed over the pattern and removed to test the resistance quality of the coating.
- Quick
- Qualitative
- Results are judged on a 0 – 5 scale
- It only requires a utility knife and pressure-sensitive tape
- Specifically for paints and coatings
- ASTM D3359 standard testing method (ISO/IEC 17025:2017 (A2LA) Accredited)
Knife Test
Technicians cut the coating in an “X” shape, then lift it from the substrate.
- ASTM D677
- Qualitative
- 0 – 10 scale evaluation
- Applicable to single coat or multi-coat
Scrape Test
A rounded stylus is loaded onto a balance-beam tester, and the load is increased until the stylus separates the coating from the substrate.
- ASTM D2197
- Quantitative
- Test adhesion of organic coatings, including varnish, lacquer, and paint.
- Applicable to single or multi-coat
- Typically performed on a flat service in a laboratory
Pull-off Test
Inspectors attach a dolly to the test material, and force is applied to the coating at a perpendicular angle, removing the adhesive layers.
- ASTM 4541
- ISO 4624
- Quantitative
- Applicable to single or multi-coat
- Performed on-site or in a laboratory
- Performed on a flat surface
ATS performs each coating adhesive testing method at the appropriate temperature to account for materials that expand or contract when reacting to heat.
