NEW DUPONT INTERLAYERS ENABLE DIGITALLY PRINTED WHITE DESIGNS IN LAMINATED GLASS
09 November 2004 - DuPont Glass Laminating Products

The advance is based on new white ink science developed by DuPont for its SentryGlas Expressions family of decorative interlayers.

SentryGlas Expressions decorative interlayers combine ink jet and polymer sheet technology from DuPont to enable fast, custom designs in laminated glass. The technology is backed by DuPont ink jet formulating science, and the company's recent polymer material innovations for the laminated glass industry.

DuPont decorative glass venture manager David S. Cordrey explains: 'The ability to digitally print SentryGlas Expressions interlayers gives designers the freedom to create textures, images, way-finding or other visuals in safety glass. To launch the business, we adapted traditional full-colour, high-resolution printing technology to work with selected DuPont interlayers, resulting in decorative glass that meets established building codes and safety requirements.'

Adds Cordrey: 'In traditional colour printing, the substrate, for example paper, provides whiteness in the printed result. However, glass interlayers are often clear, which means whiteness needs to be added, to create white design elements. Adding white ink to the SentryGlas Expressions colour palette gives us that capability - advancing design and production options for the decorative glass industry.'

Digitally printing white imagery onto the safety glass interlayer is a precise, high resolution and easy way to customize glass and create unique environments. Compared with screen printing, using SentryGlas Expressions encourages more imaginative designs that are faster and easier to adjust. The technology also enables interesting new visual options such as gradients of colour-to-colour or colour-to-clear. And production is more environmentally friendly than acid etching, often used for frosted whites.

With SentryGlas Expressions interlayers, the resulting design is embedded inside the glass, safely protected from cleaning chemicals, abrasives, dirt and grease stains, or sources of marring or scratching.

DuPont SentryGlas Expressions white ink technology is ideal for decorative glass applications such as balustrades, space dividers, privacy glazing, and light wells.
