Anodal® SH-1 is used as an additive for hot water sealing of colorless, integral and electrolytically dyed anodized aluminum to prevent the formation of sealing deposits (smut).
Anodal® SH-1 can also be used for smudge-free sealing of coatings which are adsorptively dyed with organic dyes or combination dyeings such as the “Sandalor” (registered trademark of Interoxyd AG, Altenrhein, Switzerland) dyeings produced with Sanodure®, Sanodye® and Sanodal® dyes. In the latter case, however, a two-stage sealing method is recommended, i.e. presealing with Anodal® ASL followed by the main sealing step with water and an addition of Anodal® SH-1.
