  • What is sodium benzotriazole 40%?
  • Sodium Benzotriazole 40% is an alkaline solution of benzotriazole designed for use in aqueous systems to prevent corrosion of copper. Sodium Benzotriazole can be used in engine coolants, metalworking fluids, and water treatment. Chemceed offers a diverse product line that caters to a number of industries worldwide.
  • What is benzotriazole 99% used for?
  • Benzotriazole 99% is mainly used as antirust and corrosion inhibitor for metals (such as silver, copper, lead, nickel, zinc, etc.), widely used in the antirust oil products, as gas-phase corrosion inhibitor for copper and copper alloy, as treating agent for recirculating water.
  • Is benzotriazole soluble in water?
  • Benzotriazole is slightly soluble in water. However the solubility is high enough so that a 1% solution can be easily made. This is fairly standard practice. As stated it is not usually recommended for film. However for paper the idea is to use a little as possible to eliminate the fog.
  • Can benzotriazole be used as a stock solution?
  • It's usually used fairly dilute, like a 1% solution. I've seen lots of advice to take the dry Benzotriazole and dissolve in a small amount of water or other fairly inert solvent.... and then use that as a stock solution to add to film or paper developers. I personally wouldn't use it on film unless developing aged, already-exposed film.
