Chrome Yellow Yellow and Molybdate Orange Powder Pigments Ciba® HORNACHROME® Yellow and Ciba ® HORNA® Chrome Yellow pigments are widely used in many application fields. HORNACHROME ®-A products are distinguished by extremely high color strength and opacity. The standard hues can vary from greenish to reddish yellow (lowest number indicates to most greenish hue, highest number most reddish hue). The HORNA ® Chrome Yellow GU range consists of stabilized, brilliant shade yellows. HORNA ® Chrome Yellow GM products are highly stabilized. HORNA ® Chrome Yellow GMX products are highly stabilized and SO2-resistant. The standard hue of Ciba ® HORNA® Molybdate Orange product ranges from yellowish to bluish orange (lowest number indicates yellowest hue, highest number bluest hue). The HORNA ® Molybdate Orange ML range offers higher light fastness and SO2-resistance. Weather fastness

Light Stabilizers The Ciba® TINUVIN® and the Ciba ® CHIMASSORB® ranges consist of light stabilizers with different chemistries. The range contains two types of light stabilizer: Ultraviolet Light Absorbers (UV-A) and Hindered Amine Light Stabilizers (HALS). UV-A filter harmful UV light and prevent mainly discoloration and delamination of coatings. HALS trap free radicals once they are formed and are mainly effective to retain surface properties such as gloss and prevent cracking and chalking of paints. HALS and UV-A show when used in combination a synergistic effect. Some of the HALS presented below in addition to their light stabilizers properties enhance triboelectric charging activity of powder coatings. Our extended product range enable to offer solutions for nearly all types of coatings technologies, including conventional and UV-curable powder. Applications

Test Methods – Fastness Properties of Pigments The test methods used to assess chemical and physical fastness properties of Ciba Specialty Chemicals coatings pigment products are described below below..

Pigments – Organic and Inorganic Powder Pigments Color Index Names and numbers refer to entries in the Colour Index International, Society of Dyers and Colorists, Bradford, England, 2000.

Chemical Fastness Resistance was tested on a PES/TGIC film against the ISO Gray Scale 105 A02 (1–5) for color change (0.5 N HCl, 2.5% NaOH) (scale: (scale: 1 = seve severe re change, change, 5 = no change). change).

Density Measured in accordance to ISO 787/X and quoted in g/cm3 at 20°C.

Fastness to Weathering ISO11341 Resistance to weathering is determined on panels coated with PES/TGIC powder coating. Exposure was carried out in ATLAS Weather-0-Meter according to ISO11341 (Method 1, Cycle A). The panels were exposed for 2000 hrs. The assessment assessment was made by using the Gray Scale ISO 105 A02 A02 (1 = lowest ratin rating, g, 5 = highes highest). t).

Surface Area (Specific Surface) Determined by the “BET” nitrogen adsorption method and is expressed in m 2/g. (Ref. Brunauer, Emmet, Teller, “Journal Amer. Chem. Soc.” 57, 1954.)

Opacity The opacity/hiding power was assessed in full shade based on the contrast ( ∆E-value) over a black/white panel (Descri (Description: ption: low = low opacity, opacity, transparent; transparent; med= med medium ium opacity opacity;; high = high opacity). opacity).

Heat Stability Powder coated panels of PES/TGIC are cured at different temperatures temperat ures from from 20 min. at 160 °C up to 20 min. at 220 °C. The panels are assessed assessed versus versus the 20 min. at 160°C panel. The classical pigments are tested in an epoxy polyester resin, In this case the temperatures range is between between 20 min. at 140 °C and 20 min. at 200 °C. The given value is the temperature at which only a very slight discoloration occurs.

Color Strength ISO 784/24 The data for the color strength indicate how many parts titanium dioxide to one part color pigment or one part color pigment preparation. The higher the white pigment content needed, the higher the color strength. The data were determined in a Polyester/TGIC powder coating system, the dispersion was carried out on a double screw extruder. These figures should be taken only as a guide. Absolute ISD data is influenced very much by the specific polymer system used and by individual processing conditions.

Overpaint Resistance/Bleeding Determination carried out on full strength PES/TGIC stoved finish coated with white alkyd melamine paint and restoved for 30 minutes at 130°C. Discoloration against white background assessed using the ISO Gray Scale 105 A02 A02 (1–5) for color change change (scale: 1 = severe change, chang e, 5 = no change). change).

SO2 Resistance PES/TGIC coated full strength panels were exposed according to DIN 50018 (3 cycles, 2 liters SO2). Assessment Assessme nt versus ISO Gray Scale 105 A02 (1–5) (scale: 1 = seve severe re change change,, 5 = no change change). ).

Soluble Lead Measured in accordance to ISO 6713-2 and quoted as percentage of soluble lead.

Weathering/Durability Panels at full shade and at 1:10 white reduction (TiO 2) based on a PES/TGIC resin system were exposed for 1000 hours in an Atlas Weather-0-Meter Weather-0-Meter (Xenon burner, burner, DIN 53–387). Assessment was made using the ISO Gray Scale 105 A02 A02 (1–5) for color change change (scale: 1 = severe change, chang e, 5 = no change). change).

Chemical Fastness 0.5% of dry pigment pigment was mixed mixed with 15 ml 5 % HCI or 1% NaOH solution. After 1 hour, the color differences were assessed against the ISO Gray Scale 105 A02 (1–5) (scale: (scal e: 1= seve severe re change, change, 5 = no change). change). Solvent Fastness 0.2 g of pigment was suspende suspended d in 10 ml of solvent in a folded filter. filter. After 24 hrs the filter containing the pigment was removed and the staining of the solvent was assessed using the ISO Gray Scale 105 A02 (1–5) (scale: 1= sev severe ere chang change, e, 5 = no change) change)..
