Typecodes	Bonding Frits Also called glass 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.
