Conventional and polymeric waterproofing technologies
High-performance leather waterproofing begins at the wet-end of the tanning process. With our Densodrin® product portfolio, we offer both conventional and polymeric technologies for standard and high-performance waterproofing. Our waterproofing auxiliaries for neutralization and dispersion optimize distribution and prepare the leather for further treatment. With the incorporation of BASF’s Leather Chemicals division and Densodrin® and Densotan® brands, Stahl offers the broadest and most advanced range of waterproofing products on the market. Our waterproofing technologies are part of our Stahl Neo® portfolio, which ensures that they comply with the ZDHC MRSL.
Product | Type | Main features |

Full polymer silicone leather waterproofing
Meet our full polymer silicone waterproofing products: Densodrin® Polymeric Generation and polymeric Densotan® that together transform leather waterproofing. This is because they work every bit as well as conventional water-soluble waxes and silicones – but have a much lower environmental impact. Employing Densodrin® Polymeric Generation with the polymeric Densotan® auxiliary enables tanners and shoe manufacturers to benefit from full polymeric neutralization, re-tanning and waterproofing.
Standard and high performance conventional waterproofing
Our conventional waterproofing systems, using our synthetic Densodrin® DS, CD and CS fatliquors, offer very good waterproofing performance. Densodrin® CS is especially suitable for aniline full grain and nubuck leathers that require high Maeser flexes; Densodrin® DS is recommended for use as the sole fatliquor applied to shoe upper leathers; Densodrin® CD has high fastness properties that make it an excellent choice for use on white and pastel shades. It also is particularly recommended for leather tested by the Maeser method.
Densodrin® EN, ENS and ER are the solutions for conventional waterproofing. For leathers that need a medium to high level of water resistance, Densodrin® ENS is the waterproofing agent of choice. When it is important that the leather retains its grain tightness, but also has a very soft and smooth touch after waterproofing, we recommend Densodrin® ER, which also improves dyeing results. Densodrin® EN is suitable for waterproof leathers that are tested via the Bally method.
Densodrin® and their waterproof effect
Waterproofing auxiliaries Densodrin® and Densotan®
Our waterproofing auxiliaries for neutralization and dispersion – Densotan® A and CP – optimize distribution and prepare the leather for further treatment. Densodrin® OF and S are additives for boosting the water-resistance even further. Densodrin® OF also softens the leather and gives a smooth, silky handle to the leather.
