Black pickling and burnishing agent, liquid medium on weak acid basis, especially for aluminum (freshly blank treated aluminum)
Appearance: | blue liquid |
Application:
The solution supplied ready-for-use is to be filled into a resistant container made of GRP, HDPE or PP.
Degreasing and inserting the parts:
The parts to be blackened must be degreased before cold burnishing. In the simplest case, this can be done by washing with alcohol.
Blackening effect:
Thorough degreasing of the parts is a prerequisite for uniform blackening. Depending on the material, blackening occurs quickly. The areas on the aluminum that are to be blackened must be mechanically pretreated and made bright.
