Scientists at the Department of Energy’s Oak Ridge National Laboratory (ORNL) spent about three years developing the specialized coating, which repels water, dirt, oil and dust. It also reduces glare and resists both smudges and fingerprints. The coating consists of a thin film layer of porous glass that manipulates the contact angle of liquids and small solids like dust.
The coating was developed by depositing a thin glass film on top of glass, and heating it. Selective etching was then used to make a 3-dimensional surface that resembles coral under a microscope. The dimensional surface enables both the water repellence and the anti-glare properties.
The technology can be used to give other types of glass the same properties. It can be used on solar panels, windows, lenses and other applications. Although Samsung is the exclusive licensee for the technology for certain applications, the technology can still be licensed for use on solar panels and windows by other parties. The coating technology was recognized with an R & D 100 award in 2015.
Many advances in the field of glass coating are allowing glass to perform like it never has before. Nanoscale changes t the glass surface allow glass to take on characteristics not normally attributed to glass. Glassprimer™ glass paint is a good example of a novel glass coating technique.
Glassprimer™ glass paint makes a permanent bond with the glass surface that enables paint to adhere permanently to glass. This allows the paint to perform well even under difficult circumstances, including varying temperatures, high humidity and direct sunlight.
Glassprimer™ glass paint can also be tinted to match the paint palette of any major paint manufacturer. That allows you to incorporate Glassprimer™ glass paint seamlessly into any decorating plan.
