Enhance fullness with low-formaldehyde Relugan® technologies

Relugan® DLF and Relugan® DLF liquid are amino-resin-based retanning technologies made with a byproduct of melamine. Both technologies enhance the fullness of the skin, especially in the loosely structured regions. Relugan® technologies are highly recommended for all types of leather where very low formaldehyde content is a requirement, such as automotive leathers and children’s shoe uppers.


Renektan® technologies that use dicyandiamide-based resins

Our Renektan® portfolio offers two retanning alternatives based on dicyandiamide resins. Renektan® DC-7-IT p enables tanners to enhance fullness in the looser areas of a skin, plus it has good heat and lightfastness properties, and good grain tightening properties. Renektan® DCT-IT p can be used for strong and selective filling and tightening. It has good buffing properties and a medium handle.


Achieve excellent skin fullness with Tergotan® technologies

The amino resin retanning agents in our Tergotan® portfolio create excellent skin fullness. Tergotan® RE-5020 p is free of formaldehyde and has high filling properties. Tergotan® RE-5021 liquid is a copolymer that, when used in retanning, creates excellent grain tightness and fullness, especially in the belly area.
