The TFL COOL SYSTEM® is based on a sun reflective technology
where energy is reflected in the invisible part of the solar
spectrum. It consists of a range of selected dyes and pigments,
namely SELLA® COOL dyes and RODA® COOL pigments.

The TFL COOL SYSTEM is the first system offered to the leather
industry which is able to restrict the rise of temperature on the
leather surface, when coloured leather is exposed to sun radiation. The most significant effect can be reached with black and
dark shades, where the temperature reduction is up to 25 °C.
®
The main fields of application are automotive leather (e.g., seats,
steering wheels) and garment (e.g., motorcycle garment).

Of course the system can be applied whenever the reduction of
heat-up-effect is required. The TFL COOL SYSTEM® is patented,
which means, that the SELLA® COOL dyes as well as the RODA®
COOL pigments have to be used when exploiting this technology.
The advantages of the TFL COOL SYSTEM® through lower heating
up of the leather are:
• Improved thermal comfort
• Improved shrinking behaviour
• Improved ageing properties

Determination of reflectance in the near-infrared for the
TFL COOL SYSTEM®
TFL has developed a test method, TFL/COOL-001, to measure the
reflectance of a leather sample in the near-infrared region. The
percent reflectance at 900 nm is chosen in order to determine
if a leather sample complies with the TFL COOL SYSTEM®
specifications.
Commercially available equipment and software is used to
measure the % reflectance with an integrating sphere. The total
spectral reflectance is displayed over the wavelength range of
420–960 nm, see the diagram below. Of particular importance is
the near-infrared region from 750 to 950 nm, which determines
if the coloured leather remains cooler when exposed to solar
radiation.

To achieve the COOL effect and the other properties described,
it is mandatory to use only SELLA® COOL dyes and the RODA®
COOL pigments, and it is advisable to also use the other products
recommended in our recipes, since these products have proven
not to jeopardize the result. Please note that the system does not
work, if only one component of the recipe does not fulfil the
requi­rements regarding the reflecting properties.

Even milling drums and other equipment which was used for
“non-cool leather” prior to the treatment of “COOL leather” can
harm the COOL effect. So it is advisable to clean milling drums,
transport belt of the spray machine, etc., if you want to achieve
the optimum “COOL effect”. The system is applicable on wetblue as well as on wet-white leather.
