Rockytan RPR

Rockytan RPR is a weakly acid, naphthalene based synthetic retanning agent which is used in any type of leather. It has a very good filling effect on loose parts like bellies and shanks and is a lightfast syntan.

Application & Recommendation:

Rockytan RPR imparts the leather a very good filling and is effective in dye penetration if used together with Rockytan RR7.
Rockytan RPR can be used in neutralisation with other neutralizing agents like sodium formate and bicarbonate to decrease the superficial deposition of retanning materials. The consumption rate varies with the type of leather and is about 1-2% (based on the shaved weight) after neutralization and dye.
