List of conventional coating performance testing instruments for refractory coatings

Refractory coating is a kind of casting coating, which is generally used in foundry industry and has good heat resistance and high temperature resistance. The difference between casting coatings and general coatings is that casting coatings can withstand high-temperature metal or plastic melts, and act as a barrier between castings and molds to prevent adhesion. This article is a selection plan for several conventional performance testing instruments, including fineness, adhesion, surface tension, scratch resistance, leveling, gloss and other properties.
