Retanning with Rockytan RHP completes the chrome tanning, so different wet blues can be largely normalized. Also it can be used in pretanning and tanning, so gives a good handle and outstanding dyeability. Rockytan RHP is a chrome syntan complex used for leathers, where the chrome character has to be conserved. Leathers retanned with Rockytan RHP have the following properties:
-bright color
-excellent light fastness
-full, deep and brilliant shades are obtained with anioic dyes
-smooth grain -high tear strength with high shrinkage temperature
-high full filling and round handle
