Abstract

Low-friction coatings and glass articles with low-friction coatings are disclosed. According to one embodiment, a coated glass article may include a glass body comprising a first surface and a low-friction coating positioned on at least a portion of the first surface of the glass body. The low-friction coating may include a polymer chemical composition. The coated glass article may be thermally stable at a temperature of at least about 260° C. for 30 minutes. A light transmission through the coated glass article may be greater than or equal to about 55% of a light transmission through an uncoated glass article for wavelengths from about 400 nm to about 700 nm. The low-friction coating may have a mass loss of less than about 5% of its mass when heated from a temperature of 150° C. to 350° C. at a ramp rate of about 10° C./minute.

First claim

What is claimed is:

a low-friction coating bonded to at least a portion of the first surface of the glass container, the low-friction coating having a thickness of less than or equal to about 1 micron and comprising:
a polymer selected from the group consisting of polyimides, fluoropolymers, silsesquioxane-based polymers, and silicon resins; and
a coupling agent disposed between the polymer and the first surface of the glass body, wherein
the portion of the first surface of the coated glass container with the bonded low-friction coating has a coefficient of friction of less than or equal to 0.7 relative to a like-coated glass container;
the coated glass container is thermally stable after depyrogenation at a temperature of at least about 260° C. for 30 minutes in air; and
the coated glass container is a pharmaceutical package.

2. The coated glass article of claim 1 , wherein the low-friction coating has a mass loss of less than about 5% of its mass when heated from a temperature of 150° C. to 350° C. at a ramp rate of about 10° C./minute.

3. The coated glass article of claim 1 , wherein the low-friction coating comprises:
a coupling agent layer in direct contact with the first surface of the glass container, the coupling agent layer comprising the coupling agent; and
a polymer layer in direct contact with the coupling agent layer, the polymer layer comprising the polymer.

4. The coated glass article of claim 1 , wherein the coupling agent comprises at least one of:
a first silane, a hydrolysate thereof, or an oligomer thereof;
a chemical formed from the oligomerization of at least the first silane and a second silane, wherein the first silane and the second silane are different.

5. The coated glass article of claim 4 , wherein the first silane is an aromatic silane.
