Scratch Hardness Tester

The manufacturers of the coatings also must test the quality of the coatings and paints so that they could also rest assured that they are providing nothing but the best quality products to the customers. There are many different tests that are performed on the coatings to assess their quality and the scratch hardness is one of them. The scratch hardness of the paints and varnishes is the ability of the coatings to resist any occurrence of scratches on the surfaces under any pressure or force. The scratch hardness tester can be very helpful in testing this aspect of the paints, coatings and varnishes.

Pacorr is listed under the most renowned manufacturers and suppliers providing the best quality scratch hardness tester that is used in a variety of industries to ensure the best quality of products delivered to the customers. The paints, coatings, lacquers and varnishes are the main materials that are used in different industries as well as domestic application to be applied on a surface to provide it protection from external forces and factors. One of the basic requirements of these coatings is to ensure that they keep the surfaces covered from all sides to ensure that it does not come in contact with the external factors such as dust, moisture etc. For this it is also essential that these coating are resistant to the forces that may cause scratch on the surfaces. If the coatings are not strong enough, this can compromise the protection of the surfaces. This why the manufacturers need to keep in mind that the coatings or paints they are delivering to the customers are tested for the scratch hardness so that they can withstand the slight forces that might act against them. The scratch hardness tester is the best instrument that is used for testing the resistance of the paints and coatings against the scratching forces.

The instrument is given with a stylus that is used for simulating the scratching action on the surface being tested. There are specific loads that are applied on the stylus to obtain the required force for the testing. The instrument is them switched on and the stylus starts exerting a scratching force on the surface. Once there are visible scratches on the surface, the machine is stopped and the number of strokes are recorded that are required to bring scratches on the surface. The instrument is available in two different models that are hand operated and motorised. The instrument is designed and manufactured according to the guidelines given in the ISO standards to provided best level of accuracy and quality assurance.
