Application & Recommendation

If Rockytan RP2 being used with Rockytan RR7 or vegetable tanning agents, it will make a bleaching effect on dye. It is recommended to be used alone or in combination with other chemicals for white crusts.

Rockytan RP2 can be used in neutralization 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 1-7% (based on the shaved weight) after neutralization and dyeing.

Rockytan RP2 also makes great dispersing impact on dyestuffs, amino resins and replacement syntans.
