What test reports do ink coatings need to provide?

1. VOC emission test
Volatile organic compounds (VOCs) are a pollutant in inks and coatings, which can cause harm to the environment and human health. Therefore, ink coatings need to be tested for VOC emissions to ensure that they meet the relevant national and regional standards. The test results should include data on the total amount of VOCs, the amount of individual components, and the amount of emissions.

2. Heavy metal content detection
The heavy metal content in inks and coatings is also one of the important indicators that need to be detected, because heavy metals often cause serious harm to the environment and human health. For example, heavy metals such as lead and mercury can affect children's mental development. Therefore, ink coatings need to be tested for heavy metal content to ensure that they meet the relevant national and regional standards.

3. Weather resistance test
Ink coatings are affected by environmental factors such as climate, temperature, and humidity during use, so weather resistance tests are required to evaluate their durability and performance in various environments. The test results should include UV resistance, corrosion resistance, wear resistance, etc.

Fourth, other tests
In addition to the above tests, there are other tests that are also required for ink coatings, such as: color stability test, viscosity test, rheology test, etc. These tests can help evaluate the quality and performance of ink coatings to ensure that they meet the needs and requirements of our customers.

In short, the test report that inks and coatings need to provide includes VOC emission testing, heavy metal content testing, weather resistance testing and other aspects to ensure that they meet the relevant national and regional standards and customer needs. When choosing inks and coatings, consumers should pay attention to the relevant test reports and choose high-quality products that meet the standards.
