Electrolytic Coloring Additive（Golden Yellow Color)
LW-04 Electrolytic Coloring Additive (Golden Yellow Color) is a dark red solid powder which can get stable golden color with good lightfastness and weatherability for aluminum profiles.
1. Bath Make-up:
Name | Quantity | Unit |
Sulphuric Acid Reagent | 16 | g/L |
LW-04 | 10 | g/L |
Deionized Water | Balance | |
2. Operating Conditions:
Name | Quantity | Unit |

3. Solution Maintenance:
1) Analyze the concentration of potassium permanganate and free sulphuric acid (H2SO4) everyday, replenish in time.
2) Replenishment of LW-04 is 5kg per ton aluminum profile.
3) A small amount of precipitations during production will not influence using the coloring bath. And the precipitations should be cleaned regularly.
4) Potassium permanganate is decomposable, so it is suggested to install filtration system to improve the service life of bath solution and the quality of aluminum profile.
