Abstract

A shatter containment coating composition for glass substrates, such as the glass tubing of compact fluorescent light bulbs If the light bulb breaks or shatters, the coating aids in containing shattered glass fragments of the light bulb, as well as gases and other elements within the light bulb, to thereby aid in disposal of the light bulb and/or to prevent the escape of gases or other elements into the environment The coating may be provided in the form of an aqueous dispersion having a relatively low viscosity such that, when coated onto a glass surface having complex geometry, such as the tubing of a compact fluorescent light bulb for example, the coating can conform to the surfaces having the complex geometry The coating may be a modified polyolefin provided in one or more layers, including a base coat, and the coating may be cured to form a film at a temperature of less than 150 C.
