Benzotriazole

Benzotriazole is a corrosion inhibitor of high purity, most commonly used in yellow metal protection. Wintrol® B products are available as solids, salts and dissolved in glycols/alcohols. Solid benzotriazole products are off white to light yellow with very low odor. Wintrol® B is used as a vapor phase inhibitor and preferred for use in direct treatment of copper. Benzotriazole has a higher solubility in water than tolyltriazole, which aids in formulating.
