Colour intensifying agents

Due to their refraction index silicones excellently refresh or deepen the colours.

Gloss improving agents

An agreeably silky gloss is achieved on numerous surfaces, particularly with silicone waxes. These products are therefore ideal as components for a successful care product.

Water repellency / oil repellency

HANSA carboxy-functional siloxanes are suitable for a permanent hydrophobic finishing of leather as well as for giving a touch modification. These hydrophobic agents can be used in the wet-end leather process for achieving a special hydrophobic finishing for the high quality shoe industry, like for example sports, trekking or safety shoes, as well as for leather garment applications. The CHT special acrylic acid stearyl methacrylate copolymers are ideally used in combination with the carboxysiloxane portfolio to improve the water repellency in the high quality shoe industry or leather garment. HANSA special water repellent siloxanes can be applied on nubuck/suede or finished leather by spraying either the pure product or diluted 1:1 in water to improve water repellency after

Surface and touch modifiers

HANSA special siloxane emulsions may impart a surface modification thanks to their reactive groups. These products can be easily incorporated in a topcoat formulation, but can also be used as handle modifiers for the final leather finishing. The main advantage of special reactive siloxanes is to keep leather soft and elastic, to modify the look and the feel as well as to improve the rubbing fastness. Special epoxy-modified siloxanes improve the soil-release properties in many leather finishing sectors like for example for the automotive industry.

Process aids

HANSA silicone polyethers are mainly recommended for wet back solutions just before the re-fatting process; they are very versatile products to improve the penetration of chemicals into leather pores and to reduce the demand of water in the drum. CORIOLEN LPD is a chemical auxiliary to be used in wet-end applications especially for improving the level penetration in dyeing processes, in particular on nubuck.

Soft handle agents

HANSA silicone emulsions improve the natural, authentic look of leather providing important properties such as water repellency or softness with a waxy, silky or fatty handle. Our organomodified silicones make synthetic leather softer and more breathable and may improve the abrasion resistance in many leather finishing formulations. Elastomeric or grippy touch modifications can be achieved using special amino siloxanes.

Wetting and levelling agents

Silicone polyethers are highly efficient surface, wetting and levelling agents. They can decrease the surface tension between the solid substrate and the liquid of a waterborne leather formulation and are therefore the perfect additives to improve the wetting and levelling behavior for an excellent finishing result. In general, polyether siloxanes are ideal for almost all kinds of leather finishing formulations. CHT has a wide range of polyether siloxanes and is one of the market leaders in this respect thanks to tailor-made solutions.
