FAQ/TCP-NP Question 3
Question:
Does CHEMEON TCP-NP work as an anodize seal with black dye, specifically CHEMEON Deep Black MLW or MLB or any other dyes?
Answer:
CHEMEON TCP-NP behaves like CHEMEON TCP-HF with black dyes, which is to say it doesn't hold very well for dye applications; leaching is the typical result.
