MetaShieldGLASS™ Significantly Improves Glass Break Resistance

Transparent Nanotech Coating Improves Strength of Glass in Independent Lab Impact Testing.



MetaShield LLC, an innovator in the emerging field of advanced materials nanotechnology, today announced its patent-pending MetaShieldGLASS™ coating significantly increased the impact resistance of both tempered and untempered aluminosilicate glass in independent testing. The results were achieved using a coating thickness of approximately 90 micrometers (.09mm).


In a series of dynamic impact tests performed by Intertek, the robust MetaShieldGLASS coating increased the sharp impact break resistance of untempered aluminosilicate by 100%, and chemically tempered aluminosilicate by 150%. The latter is the most commonly used glass in smartphones and tablets worldwide. MetaShield studies determined MetaShieldGLASS is also effective in increasing the break resistance of widely used soda lime glass thicker than 3mm.


The MetaShieldGLASS coating is being sold to and applied by contract and original equipment manufacturers; it is not currently designed as a consumer product.


The lab test results have implications for several industries. Aluminosilicate glass is used in automobile windows, mobile devices, with home goods, in windows, within medical equipment, glass containers, skylights, augmented reality and ordinary eye glasses, and even on space shuttles.

“That such a thin coating can have such a dramatic effect really speaks to the miraculous promise of advanced materials,” said Martin Ben-Dayan, CEO of MetaShield. “In some cases, MetaShield’s technology can also improve sustainability by allowing for glass options that can be thinner and lighter without sacrificing break-strength quality.”


Intertek, a multinational, London-based independent third-party testing company, conducted a series of dynamic impact drop-ball tests in their Kentwood, Michigan facility — following standards and methods developed by researchers at Asahi Glass Co in Japan — comparing uncoated glass samples against glass samples that were coated with the transparent MetaShieldGLASS formula. (Drop-ball testing is a common method used to determine the average kinetic energy required to break glass. For more information on test results and methodologies, please visit
