Surface Treatment Solutions for Glass Surfaces

Glass materials present a challenge for adhesion due to their smooth, non-porous surfaces. Whether used for printing, labeling, bonding, or coating, glass surface treatment is a critical step. Glass surface treatment with corona or plasma technology improves wettability and prepares the surface for reliable adhesion. 3DT LLC offers both technologies to support high-performance requirements across a range of industries.

The Purpose of Surface Activation on Glass

Untreated glass often repels inks, coatings, and adhesives. Its low surface energy and natural resistance to bonding require treatment before processing. Applications that benefit include:

• Diagnostic devices and labware
• Touchscreens and digital displays
• Optical lenses and eyewear
• Glass containers used in packaging
• Glass-ceramic panels in electronics

By modifying the top molecular layers, corona and plasma treatment allow coatings, adhesives and decoration to securely bond to the surface.

Corona Treatment

Corona discharge uses high-voltage electrical energy to increase surface energy on glass. This method works well for the continuous processing of flat or slightly curved parts. It is frequently used for glass bottle surface treatment in high-speed production lines. Consistent results and compatibility with automation make it suitable for packaging lines and screen printing setups.

Plasma Treatment

Plasma treatment for glass surfaces creates highly reactive sites on the surface using ionized gas. This process works at atmospheric pressure and does not damage delicate parts. It is especially useful for parts with complex shapes or sensitive coatings, such as lenses, lab containers, and communication displays. Plasma treatment of glass surfaces also supports fine control over process parameters, allowing precise treatment on small or detailed surfaces.

Applications in Glass Bottles and Packaging Lines

Glass bottle surface treatment helps adhesives and labels stick during bottling and packaging. Without surface treatment, coatings may flake or labels may peel. 3DT’s systems can treat thousands of bottles per hour, integrating with conveyors and robotics as needed. This process supports industries such as beverages, cosmetics, and pharmaceuticals.

Glass-Ceramic Substrates and Specialty Glass

Glass ceramic surface treatment applies to hybrid materials used in electronics, cooktops, and specialty optics. Plasma systems are often the best fit for these surfaces due to the need for low-temperature treatment and consistent activation. These parts may require preparation before applying conductive traces, coatings, or adhesives.
