Does Caisheng water-based color paste contain halogen substances?
Regarding the issue of halogen content in water-based paint pastes, the Shanghai Caisheng Technology Department communicated with multiple testing agencies to understand that the current halogen testing by domestic testing agencies only tests 4 items. Since “astatine” is a radioactive substance, currently testing agencies do not test “Astatine” “Astatine” is not even tested! Our color paste also does not contain the radioactive substance “astatine”. Our CTH-1008 rose red pulp was submitted for inspection on March 23, 2020. After receiving the test report, the conclusion showed that the color rose red pulp does not contain halogen. The test report is shown in the figure below. (The customer requires that the individual value of special toner (color paste) be less than 600PPM, and the total value is less than 1200ppm.)
Supplement: Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), referred to as halogen. Since astatine is a radioactive element, the halogens often referred to only refer to: fluorine, chlorine, bromine and iodine.
