Strengthening glass containers

摘要

A glass container and related methods of manufacturing a glass container. A solution having a composition including a silane, a solvent, a catalyst, and water, is applied to an exterior glass surface of the glass container, at an application temperature between 5 and 40 degrees Celsius, such that the solution at least partially fills the surface imperfections to provide a room-temperature-curable cold-end coating on the glass container. Then, the applied solution is allowed to cure on the exterior glass surface of the glass container, at a curing temperature between 5 and 40 degrees Celsius.

主权项

1. A method of filling surface imperfections in an exterior glass surface of a glass container that includes the steps of:
(a) applying a solution including an amphiphile, a solvent, a catalyst, and water to the exterior glass surface of the glass container, at an application temperature between 5 and 40 degrees Celsius, such that the solution at least partially fills the surface imperfections to provide a room-temperature-curable cold-end coating on the glass container; and then (b) allowing the solution applied in step (a) to cure on the exterior glass surface of the glass container, at a curing temperature between 5 and 40 degrees Celsius, wherein step (b) is carried out at a relative humidity between 60 and 90% and for a time between 30 and 180 seconds before further processing the glass container.
