Abstract
Returnable glass bottles, particularly beverage bottles, having a natural glass surface, unmodified by a hot end process coating, having a quick curing thin coating of an amino functional polydimethylsiloxane, which does not visually change the appearance of the bottles applied to the exterior surface to increase lubricity and scratch resistance to said bottles. The coating is removable when the bottles are washed with an aqueous caustic solution. A new one-trip coating can then be applied.
