USE: 10% solution in water.

APPLICATION: Hardened steels and cast iron may not require conditioning but for the majority and especially mild steel, the use of Blackfast 551 results in a homogenous surface ready for blacking. After degreasing (and pickling if necessary) steels are clean but usually exhibit surface variations which, if not treated, can result in uneven blacked surfaces. Immersion for 1 - 2 minutes in a 10% solution of Blackfast 551 in water, prepares the surface so that consistent blacking is achieved. Immersion for a longer period is not recommended since over-conditioning leads to inconsistent blacking and patchy results.

TANK MATERIAL: Tanks should be of a suitable polypropylene.

Blackfast 551 conditioner is part of the Blackfast range of products for the chemical blacking of iron and steel at room temperature.

Blackfast Chemicals continues to improve the quality and performance of its range of products and reserves the right to modify product formulations without prior notice.
