Description

Boron-Nitride-Coating Grade A is a special coating on the basis of boron nitride. This coating shows a very good non-wetting behaviour against many metal melts (e. g. aluminium and magnesium) as well as against silicate melts (glass melts). With Boron-Nitride-Coating Grade A it is possible to coat metals, ceramics and graphite in order to protect these against aggressive melts during high temperature application.

Application

Resuspend or shake Boron-Nitride-Coating Grade A prior to use. Dilute with distilled water if necessary.
Application on clean surfaces is possible by painting or spraying. Small components can be also dipped. Porous ceramics and fiber ceramics should be damped before applying this coating.
Dry thoroughly. Do not contact wet coatings with metal melts. Additional layers may be applied after drying.
Metals are preferably coated by spraying onto warm surfaces (50-150°C).
A thin coating application (50-150µm) is favourable. Thick layers may crack during use and chip off.

Storage-Container Size

Boron-Nitride-Coating Grade A must be protected against frost. A storage temperature of >5°C (>41°F) is recommended. The containers should be kept closed. Boron-Nitride-Coating Grade A is available in 1kg-containers and 6kg-containers.

Safety Advices

According to data available to us Boron-Nitride-Coating Grade A is a non-hazardous preparation. An EC material safety data sheet is available.
