Scratch Resistance Testing

Services The scratch resistance can be established e.g. in the Taber abrasion test, where the amount of haze is established after a number of abrasive cycles. Scratch resistance can also be measured by measuring the weight loss after a number of sanding cycles. The pen test determines the indentation caused by a sharp pencil scratched on the surface with a defined force.

Scratch Resistance Testing is an important evaluation that determines the durability and wear resistance of paints and coatings when exposed to mechanical stress. A coating’s ability to resist scratches directly impacts its appearance, protective performance, and service life, making this test crucial across industries such as automotive, construction, furniture, and protective finishes.

Several standardized methods are used to measure scratch resistance:

  • Taber Abrasion Test – This method evaluates the coating’s resistance to surface wear by subjecting it to a controlled number of abrasive cycles. The resulting haze formation or surface dullness is measured to determine performance.

  • Weight Loss Method – In this procedure, coatings are tested by repeated sanding cycles, and the material loss in weight is recorded as an indicator of durability.

  • Pencil Hardness Test – Here, the indentation or scratch caused by pencils of known hardness, applied with a defined force, helps establish the coating’s surface hardness and scratch resistance.

By combining these methods, a comprehensive understanding of a coating’s resistance to abrasion, indentation, and mechanical wear can be achieved.
