Description

Yttrium-Oxide-Coating YO-E is a special coating based on high purity yttrium oxide (Y2O3-Content 99.99%). Yttrium oxide is the thermodynamically most stable oxide and is suitable for extreme operation conditions. This coating - similar to house paints - on water base shows an extremly good stability with reactive melts such as Ti, Cr, Zr, Hf and Nb and can applied on ceramics, graphite and steel.

With Yttrium-Oxide-Coating YO-E high purity melts can be produced in a very simple way. Therfore it finds application both within the area of reserach and development as well as in production, for example with the investment casting of Ti-alloys.

Yttrium-Oxide-Coating YO-E can be used both at air as well as in the vacuum and inert gas to 2200°C (3992°F). On graphite an application to approximetaly 1550°C (2822°F) is possible.

Application

• Resuspend or shake Yttrium-Oxide-Coating YO-E prior to use. Dilute with ethanol if necessary.
• Apply coating on clean surfaces by brushing or spraying. Additional layers may be applied after drying.
• A thin coating application (<200µm,) is favourable. With a thick coating application exists the danger of cracking and chipping off.

Storage-Container Size

Keep container tightly closed and store product in a well ventilated and cool place. Yttrium-Oxide-Coating YO-E is available in containers of 1000ml.

Safety Advices

Yttrium-Oxide-Coating YO-E contains ethanol (ethyl alcohol) and is labelled highly flammable. Use in well ventilated areas only. An EC material safety data sheet is available.
