Innovative Solutions

Sustainability is a major challenge in our industry and Stahl is fully committed to the environmental and social responsibilities that come with our leadership position. We see our sustainable solutions as a great opportunity for Stahl, to gain a competitive edge and to drive operational excellence. We are constantly working on ways to improve the environmental footprint linked to our activities, and we believe our products and innovative solutions contribute to a better future.

Leather Chemicals & Finishing

Proviera® - Probiotics for Leather™
The early (‘beamhouse’) stage of the leather process requires the use of chemicals to clean and prepare the hide for tanning. Proviera® - Probiotics for Leather™ are metabolites derived from controlled fermentation using natural ingredients. The use of these products can reduce the effluent load during the cleaning process while improving leather quality. Stahl has acquired the rights to promote and sell the Proviera® - Probiotics for Leather™ product range into the industry. 

Stahl EasyWhite Tan™

The main environmental benefit of using the Stahl EasyWhite Tan™ chrome-free system is the significant reduction in consumption of water, salt and energy in the leather tanning process. Sales of this unique product doubled in 2015 vs. 2014 and it is becoming an increasingly common choice for customers who value a simpler, more sustainable tanning process without compromising on the quality of the leather.

The Stahlite® system of products enables customers to reduce the weight of leather while maintaining its full thickness. By using carefully selected processing chemicals, no concessions are made to the tear strength and natural look and feel of the leather. Lower weight leather has obvious benefits in the automotive and aircraft industries as 20-30% weight reduction vs. regular processed leather can be achieved. Sales of Stahlite® are growing steadily. 

Bio-based PolyMatte®
Stahl’s PolyMatte® technology is built around water-based polyurethanes which form a matt and smooth surface structure during the film forming of coatings. It is used extensively by Stahl customers in the coatings and leather industries respectively. As part of the PolyMatte® portfolio of products, Stahl has developed bio-based PolyMatte® which is partially based on renewable plant-based resources instead of traditional petroleum based materials. Its soft feel and matt surface properties have been maintained. 

Stahl Neo
Our portfolio of compliant and sustainable leather finishes.  The product line, launched in 2016, offers products that not only already comply with Zero Discharge Hazardous Chemicals (ZDHC) Manufacturing Restricted Substances List (MRSL), but even go beyond this standard, targeting an even wider range of chemical substances. The product portfolio is especially interesting to tanneries that value health, the environment and the future of their business. The leather finishing product group includes top coats, base coats, and so on.

Performance Coatings & Polymers

Stahl EVO®
This is our new generation of polyurethane based products for use in the manufacture of garment and footwear. Topcoats, skins, adhesives, foams and pigments are all part of this constantly expanding range of products. The Stahl EVO® portfolio is ZDHC MRSL-compliant and the products also allow customers to eliminate the use of DMF in their process, reducing water and energy consumption at the same time. Sales of Stahl EVO® products tripled in 2015 vs. 2014 and we expect the strong growth to continue as our customers switch away from solvent based products.

Powder Coatings

Homes and workplaces are increasingly being furnished with natural materials. As architects and interior designers opt for sustainablematerials, these spaces also contain fewer products that are harmful to your health. Powder coatings for wood are a good example, as they are free of heavy metals and have zero volatile organic content. In July 2015, Stahl entered into a joint venture with OEM NuTech, an innovator in powder coatings for heat sensitive surfaces. Like Stahl, OEM NuTech has a strong focus on sustainability and their eco-friendly coatings are now a key part of Stahl’s portfolio in the architectural coatings segment.

Bio-based Polyurethanes
Designing water-based polyurethanes using renewable raw materials is not new. Stahl has introduced several products based on this idea and bio-content levels of 35% can be achieved. Our vision, however, goes beyond that: we have begun working on high-performance polyurethanes which contain over 80% bio-content. More details about this breakthrough technology will follow soon.
