Open the CIPO recordAbstract From the Canadian patent
The strength and durability of an adhesive joint between two glass components or a glass component and, another element can be improved by preventing or retarding migration of ions present in glass to the, glass-adhesive interface. This can be effected by coating the glass surface at the joint with a submicron, layer of silicon dioxide (SiO2) aluminum oxide (Al2O3), a multi-layer coating containing silicon dioxide, or another ion-migration retarding material.

Why it's free to use
- Filed July 16, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 16, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 16, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
