Zypcoat YAG
Zypcoat YAG is a water-based Yttrium Aluminate (YAG, 3Y2 O3 *5Al2 O3 ) coating that has very high thermodynamic stability due to its high Yttrium Oxide content of 57 wt.% – and thus is non-reactive with many metals and alloys. Zypcoat YAG coating has very good chemical and erosion resistance, whether applied to metal or ceramic substrates. Forming 100% YAG after outgassing at 500-600 C, Zypcoat YAG has a very high upper use temperature (est. 1700 C). As a barrier layer to prevent reactions, Zypcoat YAG can be used to stop sticking with stacked metal plates during heat treating. This coating works well on ceramic and metal substrates.
