    The mild filling effect of Shenesin JB-S gives leather softness and elasticity, it is recommended to use in production of garment, nappa and upholstery leathers where the tightness of grain, softness and low density are critical.
    Shenesin JB-S enhances the buffing capability and cutting yield, it can be also used in production of soft corrected grain leathers and nubuck.
    Recommended dosage: % based on shaved weight.
    Sheep Nappa: up to 5
    Light weight bovine Nappa: up to 4
    Upholstery: up to 5
    Retanning of vegetable leather: up to 4
    Nubuck: up to 5
