Oil Blacking Fluid

There are a number of reasons to use oil blacking solution on machined metal parts and components, the main one being corrosion resistance. The black coating acts as an absorbent layer essentially bonding the sealant to the metal, enhancing its resistance to corrosion, even in salt water conditions.

The smooth black surface looks attractive and gives the appearance of durability; if you are a manufacturer this can make your product look more appealing to buyers. It is highly economical compared to other metal coatings and has a high degree of dimensional uniformity with minute thickness, especially when compared to electro plating.

Here at Darwen Diesels we stock an excellent quality oil blacking fluid, which is available in a 5 litre container.

The product is called Black Diamond and it has been formulated specifically to produce a chemical black finish on any mild steel and cast component surface and is an essential product for use in any diesel workshop or test room.
