PRODUCT INTRODUCTION
description
1H-Benzotriazole (BT) is a chemical used in a wide variety of industrial, commercial, and consumer products. Tolyltriazole (TTR) and 5-Methyl-1H-Benzotriazole (5-Me-BT) are chemicals closely related to BT and have similar properties and uses. These chemicals are used as corrosion and ultraviolet (UV) light inhibitors, aircraft de-icing agents, plastic stabilizers, and anti-fogging agents. They are also used in some types of pharmaceuticals, fungicides, paints, and coatings. 1, 2 BT, TTR, and 5-Me-BT are part of a large family of chemicals known as benzotriazoles.
