Purpose and method of coating hardness testing
The hardness of the coating industry is generally defined as the ability of a material to resist permanent deformation. This includes resistance to scratching and abrasion as well as resistance to penetration.
In the coating industry, hardness measurement can be used to determine the resistance of coatings to conventional abrasion, and can be used to determine whether the coating is completely cured.
According to different needs, the methods of measurement hardness are also different. Some are for testing coatings, and some are suitable for testing matrix materials, such as metals, plastics, cameras, etc.
Coating hardness testing method
There are several tests for resistance to scratching and abrasion, and a variety of instruments can be used to assess the resistance of coatings to scratching:
1. Pencil Hardness Tester - imprint
2. Neck durometer - scratch
3. Clement scratch resistance test - scratch/score
4. Scratching and cutting Tester - scratching
5. Swing rod hardness - swing
There are also several test methods for resistance to penetration, evaluating the penetration resistance performance of coatings, and when the weight of the tool is known, use its penetration depth to show the penetration resistance of coatings:
1. Buchholz
2. Barcol
3. Shore
