Coating Pyrotek Offers Coatings for Aluminum Operations

| Editor: Isabell Page

As molten metal is poured, it can have serious wear and erosive effects on metal substrates. A properly applied coating will deflect that erosive effect and increase the life of a mould. Therefore Pyrotek offers now also coatings for aluminum operations.

“Boron nitride is chemically nonwetting to molten aluminium, prevents erosion to substrates it’s applied to, and will last multiple casts on sow moulds and ingot moulds.”, quotes Global Product Manager George Stavnes at Pyrotek.

Aluminum and foundry operations globally use high-temperature coatings available through Pyrotek to stop molten aluminum from sticking to contact surfaces where it is melted, transferred, and cast.

These coatings, often made of boron nitride (BN), also extend the life of both ceramic and metal substrates in aluminum operations, improve ingot and sow release from moulds, enhance surface appearance, and can reduce labour and downtime costs from frequent recoatings.

About Pyrotek

Pyrotek offers BN coatings by ZYP Coatings Inc., of Oak Ridge, Tennessee, USA. BN is chemically inert in contact with molten aluminum, zinc, and other nonferrous metals. Pyrotek also has its own internally manufactured line of coatings, as well as dry parting agents.

Pyrotek has more than 30 core coating products, with a variety suited for the aluminum industry. They can be applied to anything in contact with molten aluminum. In addition to nonwetting, BN Hardcoat and BN Lubricoat ZV are highly adhesive to prepared surfaces and exhibit excellent erosion resistance in high-wear areas.

Pyrotek recommends appropriate surface preparation, removing loose organics or slag, to get the maximum service life from a coating. Contact a Pyrotek application engineer to find the best coating for a specific process.
