Definitions

  • the boric acid dispersion also contains other constituents, such as complexing agents and stabilizers.
  • complexing agents are nitrilotriacetic acid, ethylenediaminetetraacetic acid, gluconic acid and / or citric acid, preferably phosphonic acids or phosphonocarboxylic acids, such as 1-hydroxyethane-1,1-diphosphonic acid, aminotrimethylene phosphonic acid and 2-phosphono-1,2,4-butane-tricarboxylic acid.
  • the addition of the complexing agents can be up to 5 percent by weight, based on the total product.
  • a solution with a pH of 9.2 which contains 60 g / l sodium hydroxide solution (50%) and 50 g / l of the following dispersion:
