CorShield says its nontoxic S-69 corrosion preventatives — readily water-soluble powders and liquids designed utilizing Cortec’s VpCI technology — provide the water treatment industry with environmentally safe and cost efficient alternative to traditional corrosion inhibitor formulations.
They prevent corrosion and pitting while being free of nitrites, phosphates, amines or heavy metals. Building blocks are effective in low concentrations thus make an economical solution and give products added market value, the company says.
CorShield S-69 Powders and Liquids are building blocks that provide multimetal protection, including galvanized steel and yellow metals. The VpCI®s form a strong monomolecular layer on the metal surface that protects in all three phases: liquid, vapor, and the vapor-liquid interface.
CorShield®S-69 Powders and Liquids also provide water treatment companies with the ability to incorporate Cortec VpCI technology into their specific formulations. The concentration of S-69 inhibitor in an application can be easily monitored with a molybdenum tracing kit, or with UV spectroscopy. A molybedenum-free version (S-69 PMF), and lower-pH version (S-69B,) of S-69P are also available.
