Anodal® SH-2 is used as sealing additive for clear anodized, integral color anodized or electrolytically dyed aluminum and prevents the formation of sealing smudge.
Anodal® SH-2 can also be used for the smudge-free sealing of coatings which are adsorptively dyed with organic dyes or of combination dyeings such as those produced with Sanodure®, Sanodye® and Sanodal® dyes. In this case two-stage sealing is recommended, i.e. presealing with Anodal® ASL and then sealing with water and an addition of Anodal® SH-2.
