Abstract: The treatment of textile articles, such as sleeves made of mineral fibers of the type that are used with automotive exhaust system components, by impregnating the textile articles with treatment compositions of various formulations including fluoropolymers and/or mixtures of fluoropolymers with co-resins, followed by heat treatment to cure the compositions, thereby providing protection against impact damage to the sleeve. The treatment serves to impart enhanced resistance to damage of the sleeve by holding the overall fibrous structure of the sleeve together during impact such as by stone impingement, even if underlying fibers themselves are broken or damaged.

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.

Abstract: The invention relates to a combination of compounds and a process using such combination useful for reducing or preventing coke formation in thermal cracking furnaces such as ethylene steam crackers.
