Abstract

In order to provide a high temperature resistant adhesive based on water glass which is particularly suited for sticking metal substrates and which remains gas-tight and does not lose its electrical insulating properties even at high operational temperatures, it is proposed that the adhesive should comprise an additive in the form of boron nitride.
