Chemtan, headquartered in Exeter, New Hampshire, USA, is an international leader in developing, producing and marketing chemicals for the leather tanning industry. We specialize in American Style Specification Leather.

Donald T. Pine, President
December 2016

In 2016, the leather industry has experienced unprecedented change charac-terized by reductions and shifting of leather production worldwide.

Leather produced world wide is down 10-12%. Wet blue exports down 25% from the USA, and a 20-25% reduction in shoe, garment, and glove exports from China.

By anyone's estimate, one would expect a major correction to be forthcoming in the world market towards much lower hide prices given supply and demand imbalances.

Leather should, and will regain some if not all of its previous position from recent losses in demand posed by less durable, higher carbon footprints measured in the life cycles of non leather materials into finished goods.

The market forces are driving us all towards a cleaner, safer work environment which is good as long as regulations make sense and are well supported in terms of scientifically based achievable standards.

The opportunities next year to grow, and to better service our customers with new products and customized service has never looked better.

Once again we thank our customers, suppliers, employees, and local community who collectively make it possible for our company to succeed.

No one says that finishing waterproof leather is easy but what if you had a finish oil that didn't compromise waterproofing physicals?

Chemol® 588 is a versatile finish oil. It provides a permanent rich feel and a moderate degree of darkening that does not fade over time.

What makes Chemol® 588 truly unique is that it is excellent for use on waterproof crusts and will maintain all waterproofing properties. No more sacrificing water absorptions just to get feel.

Chemol® 588 can be applied using either a hot or a cold rollcoater depending on your desired application amounts or needs.

Sometimes smaller is better. This is certainly the case when it comes to developing a leather retanning polymer needed to selectively fill the flanks and empty areas of your skins.

Chemtan® R-108 is a versatile retanning polymer which can be used to produce a wide range of leathers, from soft glove and nappa leather to firm shoe upper.

Chemtan® R-108 improves the break without compromising lightfastness. Leathers retanned with Chemtan® R-108 are also more receptive to impregnation.

Let's make white leather together.

Chemtan® M-5 is a novel approach to making chrome free leathers. It is non-yellowing, making it supremely suited for white athletic and automotive leathers. But it also imparts numerous reactive sites needed to make bright and dark shades.
