Chrome 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 canvary from greenish to reddish yellow (lowest number indicates to most greenish hue, highest number most reddishhue). The HORNA® Chrome Yellow GU range consists of stabilized, brilliant shade yellows. HORNA® Chrome Yellow GMproducts 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 numberindicates yellowest hue, highest number bluest hue). The HORNA® Molybdate Orange ML range offers higher light fastness and SO2-resistance.

The Ciba® TINUVIN® and the Ciba® CHIMASSORB® ranges consist of light stabilizers with different chemistries. The rangecontains 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 oncethey 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 inaddition 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.

For Absorbance Spectra of selected Ultraviolet Light Absorbers (UV-Absorbers), see Appendix.

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

Color IndexNames and numbers refer to entries in the Colour IndexInternational, Society of Dyers and Colorists, Bradford,England, 2000.

DensityMeasured in accordance to ISO 787/X and quoted ing/cm3 at 20°C.

Surface Area (Specific Surface)Determined by the “BET” nitrogen adsorption methodand is expressed in m2/g. (Ref. Brunauer, Emmet, Teller,“Journal Amer. Chem. Soc.” 57, 1954.)

Heat StabilityPowder coated panels of PES/TGIC are cured at differenttemperatures from 20 min. at 160 °C up to 20 min. at220°C. The panels are assessed versus the 20 min. at160°C panel. The classical pigments are tested in anepoxy polyester resin, In this case the temperatures rangeis between 20 min. at 140°C and 20 min. at 200°C. Thegiven value is the temperature at which only a very slightdiscoloration occurs.

Overpaint Resistance/BleedingDetermination carried out on full strength PES/TGICstoved finish coated with white alkyd melamine paintand restoved for 30 minutes at 130 °C. Discolorationagainst white background assessed using the ISO GrayScale 105 A02 (1–5) for color change (scale: 1 = severechange, 5 = no change).

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

Fastness to Weathering ISO11341Resistance to weathering is determined on panels coatedwith PES/TGIC powder coating. Exposure was carried outin ATLAS Weather-0-Meter according to ISO11341(Method 1, Cycle A). The panels were exposed for2000 hrs. The assessment was made by using the GrayScale ISO 105 A02 (1 = lowest rating, 5 = highest).

OpacityThe opacity/hiding power was assessed in full shadebased on the contrast (∆E-value) over a black/whitepanel (Description: low = low opacity, transparent;med = medium opacity; high = high opacity).

Color Strength ISO 784/24The data for the color strength indicate how many partstitanium 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 powdercoating system, the dispersion was carried out on a double screw extruder. These figures should be takenonly as a guide. Absolute ISD data is influenced verymuch by the specific polymer system used and by individual processing conditions.

Soluble LeadMeasured in accordance to ISO 6713-2 and quoted aspercentage of soluble lead.

Chemical Fastness0.5% of dry pigment was mixed with 15 ml 5% HCI or1% NaOH solution. After 1 hour, the color differenceswere assessed against the ISO Gray Scale 105 A02 (1–5)(scale: 1= severe change, 5 = no change).

Solvent Fastness0.2 g of pigment was suspended in 10 ml of solvent in afolded filter. After 24 hrs the filter containing the pigmentwas removed and the staining of the solvent wasassessed using the ISO Gray Scale 105 A02 (1–5) (scale:1= severe change, 5 = no change).

SO2 ResistancePES/TGIC coated full strength panels were exposedaccording to DIN 50018 (3 cycles, 2 liters SO2). Assessment versus ISO Gray Scale 105 A02 (1–5) (scale:1= severe change, 5 = no change).

Weathering/DurabilityPanels at full shade and at 1:10 white reduction (TiO2)based on a PES/TGIC resin system were exposed for1000 hours in an Atlas Weather-0-Meter (Xenon burner,DIN 53–387). Assessment was made using the ISO GrayScale 105 A02 (1–5) for color change (scale: 1 = severechange, 5 = no change).
