Evaluate Scratch Resistance of Paints

Evaluate Scratch Resistance of Paints using Scratch Hardness Tester

Automobile industries assemble large parts from a variety of materials. All these parts have protective coating applied to enhance the look or provide additional durability to the substrate. The uppermost layer is a clear coating that saves the underlying layers or substrate from reaction to chemicals and sunlight but also protects from mechanical damage that can result in surface scratches.

The product that has paint coatings has elongated life, therefore it is important to evaluate the scratch resistance so that it maintains minimum visual appearance. Any material whether it has cosmetic appeal or used for functional performance, the damage to its surface will keep customers away and have the wrong perception of its quality.

Paint hardness can be analyzed after the chemical reaction between paint and the substrate it adheres to. Paint is used to protect the surface from any kind of abrasion or scratches. Environmental stress, humidity, thickness of paint and its type play an important role in influencing the hardness of the paint (Paint Testing Instruments).

Paint hardness testing helps in determining the flexibility of scratching, rubbing, and other external abrasions. Industries must understand the hardness of their coatings to know whether it is appropriate for their intended application.

Scratch Hardness Tester works by using a test panel that is clamped maintaining uniform speed while needle scratches the surface. By increasing the load, user can monitor at which load needle is penetrating. The testing machine is used to perform tests that determine resistance to scratch under a specified load. The machine has wide variety of usage of products such as paints, lacquers, and varnishes. The paint and plating industry uses this apparatus to check the quality control of paint and varnishes.

It is important to test the quality of paint and coatings so that customers get the best quality of products. Various tests are performed on the coatings to assess the quality. Pacorr is one of the best manufacturers and supplier providing the best quality scratch hardness tester used in variety of industries to ensure the best quality of products delivered to the customers. Manufacturers need to consider the coatings and paints against the scratching forces. The instrument is available in two different models that can be hand-operated and motorized. The instruments adhere to international standards and provide the best level of accuracy and quality assurance. With the best quality materials used to build the machine, the instrument ensures best level of protection to the surfaces where it is applied.
