Birchwood’s TRU TEMP XT forms black oxide on difficult-to-blacken materials

Birchwood Technologies

The new TRU TEMP XT mid-temperature process, available from Birchwood Technologies, forms a durable black oxide finish on difficult-to-blacken steel, iron, and most stainless steel alloys. It forms a satin black magnetite finish that protects critical surfaces in storage, shipment, and startup while resisting galling and aiding break-in.

Operating at 230 to 260 degrees F, the process is used as a two-stage chemical reaction, with OXYPRIME® XT Primer/Prep followed by TRU TEMP XT. The process takes 30 min. The resulting black finish can be sealed with an appropriate rust preventive topcoat.
