Versatile, high-performance acrylic polymer retanning agents

From retanning agents with high light fastness and heat resistance to retanning agents with a high-electrolyte stability or bleaching properties, we have your requirements covered.

High-fastness retanning with Relugan®

Relugan® FS is an alternative to conventional resin tanning. Besides offering excellent heat resistance, light fastness and migration resistance, it also creates excellent fullness, even in leather taken from the belly and flank areas. It is formaldehyde-free and the residual monomer and inorganic salt content is low. This increases the overall sustainability of the leather.
Relugan® SE is an acrylic polymer retanning agent with high-fastness properties. It is very effective in retannages applied to soft milled leather. Relugan® SE can be used to manufacture elegant chrome-tanned or chrome-free leather with a natural appearance and extremely high fastness. This makes it a very suitable retanning agent for automotive leathers.
For shoe upper and leather goods, Stahl recommends Relugan® RV as your tanning agent of choice. It improves the fullness of chrome-tanned leathers and the tightness of the grain. It also reduces the elasticity of the leather. Relugan® RV is very effective when used with vegetable tanning agents and speeds up the vegetable tanning process.

Improve grain tightness of leathers for shoe uppers

Another recommendation for all types of shoe upper is Renektan® ZY/C. It has good heat and lightfastness and improves the tightness of the grain. It is also suitable for tight nappa products.

Ensure excellent filling action and grain tightness with Tergotan®

For exceptional grain tightness, tanners can best use Tergotan® PR liquid. Suitable for garments and upholstery, Tergotan® S concentrated liquid can be used for all types of soft milled leather. It has excellent milling and buffing properties. Tergotan® S concentrated liquid is part of our Stahl Neo®sustainable portfolio.
