It consists of a range of selected dyes and pigments, namely SELLA® COOL dyes and RODA® COOL pigments. Black Grey ✓ 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).

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 >> Application Scarlet Ocean Mint Citron 4 3–4 4 3–4 4–5 3–4 2–3 3 4 4 4 4–5 4–5 5 ✓ 3–4 2–3 3–4 4–5 4–5 4–5 ✓ 4–5 4 4 4 4–5 4–5 4–5 ✓ 3–4 3–4 4–5 4–5 * MIF (Migration into Finishing) is a TFL internal test method. 5 ✓ ✓ ✓ ✓ ✓ /// Measurement of the COOL effect >> TFL/COOL-001 test method: SELLA® COOL Wo Co 4–5 4–5 4–5 ✓ COOL dyes and RODA® COOL pigments Scarlet Ocean Mint Citron 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. Reflection in % 100 90 70% 80 70 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. 60 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. 10 >> Safety Please refer to our safety data sheet. 50 40 30 20 0 420 480 540 600 660 720 780 840 900 960 Wavelength (nm) Typical white leather A typical spectral reflection curve over the wavelength range from 420 to 960 nm for a black leather prepared according to the TFL COOL SYSTEM®.
