Pigment Heavy Metals

Pigment heavy metals refer to colorants containing metals such as lead, cadmium, and mercury. Their content is detected using atomic absorption spectroscopy to control the safety standards of products like paints and plastics, thereby preventing human exposure to excessive levels of these substances.
Selection
When selecting, it is essential to confirm that the product complies with industry standards for heavy metal limits. Verify the specific values of lead, cadmium, and other elements in the test report, prioritize types with content below regulatory limits, and make selections based on compatibility with the production process.
