EPIZOTAN FPR imparts the leather a very good filling and is effective in dye penetration if used together with Epizotan FF7.

EPIZOTAN FPR 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 1-2% (based on the shaved weight) after neutralization and dye.
