How firmly are the SCHOTT Nexterion® coatings attached to the glass?
The Nexterion® silane coatings are generally resistant to most aqueous buffer systems, and many organic solvents, (such as DMSO, alcohols like iso-propanol, ethanol, methanol, and ketones like acetone or toluene), but obviously SCHOTT has not been able to test all possible solvents. The Nexterion® silane coatings will remain attached to the glass in solutions with pHs of between 2 and 10. Delamination of the silane coating is only observed after a prolonged treatment under highly alkaline conditions (over pH 11). SCHOTT coatings remain stable under a large range of temperature as well: For the slide E, AL, A+ and AStar coatings – temperatures of -20C up to 100C will not affect the coating. However, please note that these statements refer to the silane bonds to the glass surface. The active groups of the coatings may well be adversely affected by some of these treatments.
