Polyacrylic softening and retanning agent The leather chemical Syncothan TL is a polyacrylic softening and retanning agent. Characteristics Syncotan TL reacts with the fatliquor and improves the compactness and stabilizes the fibre structure without losing softness. The leather chemical Syncotan TL disperses fatliquor emulsions and promotes their deep and even penetration. This positively affects the exhaustion of the fatliquor bath. Syncotan TL can be added at almost any stage of the retannage and fatliquoring. TDS request Request a TDS of product TDS Sample request Request a sample of product Request
