USE: As supplied or 50% solution in water

APPLICATION: Blackfast 716 is a Light alkaline degreaser used in the preparation of clean metal surfaces prior to the blacking process. Used in a dilution of 50% in water for 15 – 20 minutes, Blackfast 716 will degrease iron and steel at room temperatures. However, immersion times will vary according to the condition of the component. More heavily oiled and greased parts can be treated first using Blackfast 250, a solvent degreaser, and finished off effectively with Blackfast 716

It is important to maintain the strength of Blackfast 716 by removing 10 % of the tank content every 1 -2 weeks and replenishing with fresh material. The effectiveness of a Blackfast 716 tank can be checked regularly by examining the water rinsed component after degreasing. If water rinse drains unevenly showing dry patches, the surface is still contaminated with oil or grease and requires further degreasing through a fresh Blackfast 716 tank.

TANK MATERIAL: Tank should be made of mild steel or suitable grade of polypropylene

Blackfast 7I 6 light alkaline degreaser is part of the Blackfast range of products for chemical blacking of iron and steel at room temperature
