Brown fused aluminum oxide is used is used both in the surface preparation process before the application of a coating and in many instances, in the actual coating mix. Coatings are applied to many surface types such as bridges, pipelines and oil rigs in order to extend their useful life where durability and longevity of the structure are of vital importance. In order for a coating to properly adhere to a surface, that surface must be well prepped prior to coating. Brown fused aluminum oxide is often the preferred choice of media in the surface preparation process.
Because brown fused aluminum oxide is ultra hard and has excellent corrosion and chemical resistant properties, it is also often used as an additive to the coating mix to provide added protection against corrosion, wear and abrasion.
