Environmental protection aluminum silver paste

environmental protection aluminum silver paste

   So-called environmental protection aluminum paste, refers to meet the environmental requirements of the European Union products. Specifically, limit aluminium-silver paste containing harmful substances such as heavy metals, pbbs and PBDES, Polycyclic aromatic hydrocarbon and plasticizers. The development of environment-friendly paint determines the trend of environment-friendly silver paste. VOC in paint and coatings can cause serious air pollution, aluminum silver slurry as an important raw material of paint and coatings, in order to become environmental protection products, the VOC emission is greatly reduced must also work on aluminum silver slurry, specifically, the aluminum and silver slurry in the solvent oil does not contain aromatic hydrocarbons or very low content. It needs to add environment-friendly solvent oil (D70 solvent oil) in the stage of aluminum-silver slurry ball milling to grind, so that pigments and pigments can be environmentally friendly from the source. Heavy metals, especially lead, are also severely restricted because they are harmful to children's intellectual development. Environmental Protection Aluminum Silver Slurry testing mainly refers to SGS testing, including PAHs (Polycyclic aromatic hydrocarbon) testing, ROHs (heavy metals) testing, EN71-3 testing, VOC testing, colobenzene 17P testing, reach 168 testing and halogen testing.
