Description

Application:

The solution supplied ready for use should be poured 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 burning. 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.
