Coating composition by XRF


Coating thickness is an important variable that plays a role in product quality, process control, and cost control. By recording and monitoring the thickness of the coating, we can keep a tab to avoid over and underapplication. This helps in keeping the surface finish right while maintaining the performance as well. Coating thickness can be determined by XRF (non-destructive) or by the Colometric Method (destructive). The Colometric method is used for measuring the coating thickness and potential difference of multi-nickel coatings according to ASTMB764.

coating weight

Coating weight is determined on a test panel or part with a known surface area is first weighed as-is. This test is performed to measure the coating weight on the part in comparison to specifications requirements. Coating weight is typically performed on Anodized, and Phosphated surfaces.


The Cross Hatch Test Method is widely used to assess the adhesion of paint coatings and provides an instant assessment of the quality of the bond to the substrate. The cross hatch test is a visual comparison method for paint and powder coatings up to a specified thickness. This is a destructive test of the coating, so it is typically performed on a representative panel

Salt spray analysis to evaluate corrosion resistance (by ISO 9227 and ASTM B117)

Type of accelerated corrosion test that is performed to assess the comparative corrosion resistance of certain materials when exposed to salt spray at increased temperature levels. In this test, specimens are put inside a chamber for salt spray testing, with constant salt water spray, while the climate is maintained during the test.

Used for periodic testing to ensure anodize, plating, and other coatings meet requirements

Copper Sulphate Testing

The copper sulphate test in intended to test the surface passivity of corrosion-resistant steel parts. The test determines the presence of free iron which is often transferred onto the surface of a part during fabrication with steel components.

Surface Tension, Baume, Density/Specific Gravity

Surface tension is the key parameter which determines good leveling and wetting of a coating.
