Typecodes	Bonding Frits These melt at very low temperatures (e.g. 500C). They are used to bond together materials that can withstand some heat (e.g. abrasives, ceramics, non-oxide ceramics, metals). And as a surface smoothing agent. The main product properties are melting temperature and thermal expansion. The powders are mixed with binders, applied and then heated up and down to create the bond.
