Songwei Lu to present at 19th International Sol-Gel Conference in Belgium
PPG (NYSE:PPG) today announced that Songwei Lu, Ph.D., PPG senior
research associate and group leader for display coatings, will present
“Commercialization of Sol-Gel-Based Transparent Functional Coatings” at
the 19th International Sol-Gel Conference in Liege, Belgium. Lu will
speak at 11:30 a.m. on Sept. 5, 2017.
Lu’s presentation will highlight new performance advances in
sol-gel-based transparent functional coatings for display applications
featuring enhanced easy-to-clean (EC), anti-glare (AG), anti-reflective
(AR) and anti-fingerprint (AFP) coatings. His presentation will address
prototype sol-gel-based transparent functional coatings that PPG has
developed and scaled from 4-kilogram lab batches to 40-kilogram lab
batches at its U.S. development center, as well as commercialized in
100- to 1,000-kilogram batches at its Tianjin, China, plant.
Sprayed onto glass substrates following low-temperature cure, the
super-hydrophobic EC coating exhibits high deionized water-contact
angles greater than or equal to 115 degrees and excellent abrasion
resistance by passing at least 10,000 cycles using super-fine (#0000)
steel wool under a 1-kilogram load. The coating also achieves silk-like
tactile properties quantified by its extremely low coefficient of
friction (COF).
The sol-gel-based AG coating demonstrates gloss values between 50 and
120 gloss units (GU) with excellent pencil hardness (greater than or
equal to 8 units of hardness) and no sparkling issues on touch-screen
displays. When embedded with mono-dispersed latex particles, the coating
can be applied on room-temperature glass while maintaining similar
performance. When the sol-gel-based AG coating is combined with an EC
top coat, the coating stack also shows significant increases in stylus
pen durability.
The sol-gel-based single-layer AR coating shows transmittance increases
of 1.5 to 2 percent when applied by spray- or spin-coating on one side
of a glass substrate. When the coating is dip-coated on a polycarbonate
substrate, transmittance increases by 4 percent.
PPG’s newly-developed sol-gel-based AFP coating significantly hides
fingerprints on the glass surface and offers excellent cleanability. The
AFP coating can pass 2,000 cycles of a rubber-eraser wear-durability
test under a 1-kilogram load and 400 cycles of the same test and load in
the presence of ethanol.
The five-day 19th International Sol-Gel Conference begins on Sept. 3,
2017, and is organized in conjunction with the International Sol-Gel
Society (ISGS). The biennial event gathers the most relevant and
innovative advances in the field from the point of view of scientific
research and industrial developments. It also promotes intensive
interdisciplinary and academia-industry collaboration.
PPG is among the only companies worldwide to manufacture EC, AG, AR and
AFP coatings. It also offers one of the most complete lines of
transparent functional coatings for glass, plastic and metal substrates.
With its broad range of coatings expertise, PPG can combine its
transparent functional coating technologies into complete
pre-engineered, pre-stacked total coatings solutions. For more
