Building on 125 years of HeritageFrom our beginnings in 1891, the leather chemicals unit of BASF has built upon our strong heritage and chemical expertise to deliver a portfolio of industry-leading innovations. Ranging from the first synthetic tanning agent in 1912 to the new generation of top coat system in 2015, BASF has consistently set benchmarks and developed high performance solutions to the automotive leather industry.

As we celebrate 125 years of leather breakthroughs that attest to our dedication to quality and excellence, BASF continues to provide a comprehensive product range that covers the complete leather-making process, from beamhouse to finishing. Working continuously on product development and process optimization, we help our customers produce leather in a sustainable way which enable them to meet the stringent requirements set by the brands and OEMs. Our range of finishing solutions for automotive leather have zero add-on of NMP* and NEP*. At BASF, we offer value-added solutions that are backed by consistent high product quality, consumer safety and customer service.

Understanding Our CustomersAs part of the BASF automotive industry group, our leather chemicals unit along with other businesses, has participated in many automotive industry platforms and events globally. These occasions presented opportunities for networking and in-depth discussions. Over the years, these experiences have helped us foster stronger collaboration both internally and externally and kept us updated on the latest trends and challenges facing the automotive industry. Leveraging on our strong leather expertise and networking, our partners worldwide can count on our support to produce state-of-the-art automotive leather with exceptional quality. Customers can be assured of our know-how to meet the demanding standards that are expected from today´s automotive leather:

Soft but resilient

Durable, soil-resistant and easy to clean

Non-repolishable; matt and “soft touch” surfaces – in spite of intense wear

Perspiration- and migration-resistance – ideal for accommodating creative designs

Low in VOC*, fog and odor – reduced emissions in car interior

* NMP = N-Methylpyrrolidone, NEP = N-Ethylpyrrolidone, VOC = Volatile Organic Compounds

Choosing BASF as your working partner: 125 years of leather expertise

Saving with DryFast system for a sustainable beamhouse process

Eusapon® OC, Eusapon® W and Basozym® S20 are highly effective soaking auxiliaries that eliminate multiple washings

Mollescal® HW and Basozym® L10 facilitate the removal of hair roots, scud and reduce sludge in the effluent during the liming process

Main Benefits of DryFast Beamhouse Innovation

1. Saves WaterRequiring less washings, DryFast reduces waterconsumption in wet blue making by up to 60%*, thereby reducing costs and the amount of effluent produced. Less washing at all stages.

2. Reduces Effluent and SludgeCleaner effluent is produced with sludge reduction ofup to 50%* that lowers water treatment costs. WithDryFast, there is also zero discharge of hazardouschemicals that harms the environment. Lower emissions and low dosage of chemicals.

3. Saves TimeThrough process optimization, production time isshortened by at least 12 hours* as compared toconventional beamhouse processes.Improvedprocessefficiencythroughhigh exhaustionofchemicals.

Use high quality polymers with low residual monomer content and replace fatliquors based on e.g. fish oil with polymeric softening agents (Densodrin® DP, Relugan® Soft)

Replace conventional retanning agents by high quality synthetic tanning agents (Basyntan® IS, FO)

Use solvent free finishing products with zero add-on of plasticizers (Astacin®)

Taking Steps Towards Optimizing VOC in Leather Production:

Finishing solutions for natural-looking and high performance leather

Higher Durability Performance standards in automotive leather are exceptionally stringent due to the high expectations regarding the durability of the leathers.

End-consumers expect their automotive seats to deliver reliable and unsurpassed usage properties of leather and retain their beauty throughout the life cycle of their cars.

With this in mind, BASF’s new generation of top coat system is formulated to achieve outstanding results such as:

Highest level of rub-fastness Outstanding wear resistance Excellent heat resistance

The final result is an achievement of +20% long-lasting durability compared to conventional systems currently available in the market to ensure that leather seats last as long as possible.

Main Benefits With New Generation of Top Coat System

Highest Degree of Jet-blacknessCombining the deep jet-blackness of both Astacin® Novomatt DD and Astacin® Matting AR allows customers to achieve:

Highest degree of jet-blackness available in the market Deep, matt colors that will not be repolished by usage

The new top coat system helps our customers achieve natural long-lasting beauty effects of their leather automotive seats.
