"Today's newer aluminum engines create a problem for water-glass based sealers. Aaluminum expands and contracts about 33% more than steel.

Todays newer vehicles require a liquid sealer that can flex and expand with the engines aluminum parts so as to not just crack-away. So far, the only brand I've found that doesn't use water-glass as a main ingredient is Dura-Seal..."

Wikipedia Definition:
A head gasket is a gasket that sits between the block and cylinder heads in an internal combustion engine.
Its purpose is to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders; as such, it is the most critical sealing application in any engine, and, as part of the combustion chamber, it shares the same strength requirements as other combustion chamber components.
