DuPont™ Hydrology™ helps leather accessories such as briefcases, handbags, wallets and suitcases last longer and look better—even after repeated tough use under challenging conditions—thanks to its superior protection against the weather; exceptional colorfastness; and ability to dry quickly. And, because DuPont™ Hydrology™ is a total systems approach, not a coating that is applied to leather, it will not have a negative effect on the breathability, feel or scent of the leather.

Superior resistance properties

In numerous standardized tests, leather tanned with DuPont™ Hydrology™ consistently resisted water penetration and absorption far better than conventionally-tanned leather.

For example, in a severe simulated rain test conducted according to ISO 9865, samples tanned with DuPont™ Hydrology™ exhibited no leak-through even up to four hours of testing.

DuPont™ Hydrology™ also helps leather resist staining.* Dry soil doesn’t stick and most spills—including tough challengers such as soy sauce, red wine, fruit drinks and coffee—wash right out. Soil resistance was tested according to a modified AATCC TM123 and stain release was tested according to a modified AATCC TM130.

Exceptional colorfastness
Accessories made of leather tanned with DuPont™ Hydrology™ maintain their original color and good looks over time, even after being exposed to the harsh conditions of daily life—and frequent cleanings. What’s more, these items have excellent resistance to color transfer, giving consumers peace of mind that their clothing or important documents won’t be damaged by picking up unwanted color from a wet suitcase, briefcase, handbag or wallet.

Colorfastness was tested according to ASTM D5053 on leather samples tanned with DuPont™ Hydrology™. The leather resulted in little to no transfer of color or dye.

Quick-drying nature
The ability to dry quickly is an important feature for leather accessories. After all, who wants to walk around with a damp briefcase or handbag the day after a storm? Leather tanned with DuPont™ Hydrology™ performs exceptionally well.

*Stain protection achieved by using DuPont™ Teflon® technology.
