Glass articles with low-friction coatings
First Claim
1. A coated pharmaceutical package comprising:
- a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container formed from a borosilicate glass composition and the first surface is an exterior surface of the glass container; and
a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising;
a polymer selected from the group consisting of polyimides, fluoropolymers, silsesquioxane-based polymers, and silicone resins; and
a coupling agent layer disposed between the polymer and the first surface of the glass body,wherein the coefficient of friction of the portion of the coated pharmaceutical package with the low-friction coating is at least 20% less than a coefficient of friction of a surface of an uncoated pharmaceutical package formed from the same glass composition.

Abstract
Coated pharmaceutical packages are disclosed. In embodiments, a coated pharmaceutical package includes a glass body comprising a first surface. A low-friction coating may be positioned on at least a portion of the first surface of the glass body. The low-friction coating may include a polymer chemical composition. A light transmission through the coated pharmaceutical package may be greater than or equal to about 55% of a light transmission through an uncoated pharmaceutical package 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.
