How to use a salt spray tester to test the quality of automotive coatings?


By means of continuously accelerated research methods, the salt spray tester can obtain the salt spray test resistance of electrophoretic coatings with different film thicknesses, different parts, and different economic structures, in order to identify and analyze that these parts of us are more prone to cause corrosion during the painting process and to take the corresponding protective technical measures.

automotive coatings

When people buy a car, they are often concerned about how good it looks and the quality of the surface coating is a visual assessment of the quality of the car. With the deterioration of the global environment, people are demanding good corrosion resistance from automotive coatings. How improve the corrosion resistance of a car is one of the key issues that many car manufacturers have to face, and a salt spray tester can solve this problem.


As one of the four major processes in automotive manufacturing, paint is used primarily for corrosion protection and decoration. It is an important rust protection project for automobiles. The coating provides complete protection for the body by applying high corrosion protection coatings to improve electrophoretic penetration, increasing the film thickness of each coat, applying sealants to the welds, and spraying corrosion protection wax. However, defects or deficiencies in body construction, design, and manufacture can still result in some parts of the body being more susceptible to corrosion than others. Therefore, these areas of corrosion should be identified and analyzed during the painting process, and protection measures are taken accordingly. It is important to use these corrosion delamination issues in the design phase, i.e. in new hairstyles.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
