20-Mar-2002

03/20/02 - Very low VOC content - High fastness - For all types of leather

Lepton®Top HT is based on BASF's innovative chemistry, and this new product offers tanners many advantages in finishes applied to leather. "HT" stands for High Transparency, High Technology and high stability at High Temperatures, which are the most important features of this new product.

High Transparency The new Lepton Top HT dries to form a crystal-clear film on the surface of the leather. It is particularly effective in combination with other products, and it ideally complements the other acrylic and polyurethane top coats and binders supplied by BASF. It can be used in combination with the other auxiliaries in BASF's range of products for the leather industry. A particularly useful advantage of Lepton Top HT is that it remains transparent at all times. The leather retains its natural appearance and has an elegant, natural handle.

High technology and stability at high temperatures Lepton Top HT is the product of the latest manufacturing techniques. It consists of an aqueous dispersion of an acrylic polymer with a special particle structure. The advantage for tanners is that this new acrylic top coat enables the same high standards of lightfastness and rub resistance to be achieved that could previously only be obtained with top coats based on polyurethane or cellulose acetobutyrate. Lepton Top HT also has excellent resistance to hydrolysis and a high glass transition temperature, and it dries to form a tack-free film.

Economical and environmentally friendly This new finishing product reconciles the demands of economics and ecology.

Only a thin layer of finish needs to be applied to the leather.

It may be possible to dispense with crosslinking agents, depending on the application.

Lepton Top HT has a very low VOC content of less than 0.2 %.

Lepton Top HT makes it possible to obtain leather with a natural appearance and a pleasant handle, and it also satisfies ecological and economic requirements. This new top coat from BASF fulfils the demands from consumers for high performance and the demands from manufacturers of leather goods for high fastness.

The range of performance chemicals for leather and fur supplied by BASF consists of standard products and specialities for beamhouse, retanning, dyeing and finishing. BASF's integrated network strategy in the fields of research, development and production, known in German as "Verbund", is one of its strengths in the leather sector. BASF occupies a leading international position in finding solutions to technical problems, which ensures that the company and its customers have a decisive competitive advantage.
