SS Welding Black Spot Remover(PICK N PASS) 1Kg

PICKLING PASTE FOR STAINLESS STEELS:

APPLICATION:

For removal of high-temperature oxide layers and annealing colors in the areas of welds and weld areas.

APPLICATOR:

Nylon brushes of acid-resistant materials.

APPLICATION:

PICK N PASS is to be stirred with a plastic or wood stirrer before use, or shaken briefly. PICK N PASS is to be painted generously on the pickling positions. The reaction time should be observed as advised. Neutralization is then to be undertaken with PICK N PASS Neutralizer, after consulting the relative application instructions. Upon completion, the processed surface is to be rinsed under cold water, using a high-pressure water jet or hand clean with synthetic cloths.

REACTION TIME PERIODS:

• Rusty and acid-resistant steels, stainless steels 15 - 60 minutes
• Nickel and nickel alloys 10 - 20 minutes
• Copper-nickel alloys 5 - 15 minutes

The reaction time period is dependent on the quality of the working materials treated as well as on the ambient air- and materials temperature. The optimal pickling temperature is around 25 - 30° C. Work routines should be avoided in direct sunlight (due to the hazard of premature drying).

COVERAGE:

1 kg of PICK N PASS is sufficient for 60 - 90 running meters approx. of weld area.
