Chromtex has a documented commercial use as CHROMTEX™, a range of synthetic chrome oxide green pigments offered by ZWUKSO, a Polish supplier of inorganic pigments. Based on chromium(III) oxide, Cr₂O₃, these products are listed for coloring paints, plastics, concrete, rubber, ceramics, and other industrial materials.
For buyers, the main questions involve grade specifications, compatibility with the intended material, and handling requirements. Similar names in textile-related search results can also complicate identification. Checking the supplier’s catalogue, technical data sheet, and safety data sheet helps separate documented product information from general claims about color technology.
What Does Chromtex Refer To?
In ZWUKSO’s catalogue, CHROMTEX™ identifies a branded series of finely milled chrome oxide green powders used for industrial coloration. The supplier lists several grades, including GA-U, GA-R, GN, and GA, alongside additional GA variants. The series name therefore provides a starting point for identifying a product, while the grade specifies which listed option is being considered.
The spelling matters when researching the name. Chromatex Chemicals Pvt. Ltd., which includes an extra “a,” is a Pakistan-based manufacturer of textile-processing auxiliaries. Its products support pretreatment, dyeing, and finishing. Those company details should not automatically be attributed to ZWUKSO’s pigment range simply because the names look similar.

ZWUKSO and Its Chrome Oxide Green Range
ZWUKSO Sp. z o.o. Sp.k. is a Polish pigment supplier based in Siemianowice Śląskie. The company states that it was founded in 1989, initially manufacturing synthetic iron oxide pigments. It later expanded into importing inorganic pigments through cooperation with European manufacturers.
CHROMTEX™ is its chrome oxide green offering within a broader catalogue covering iron oxides, titanium dioxide, and liquid, granulated, and micronized pigments. ZWUKSO also states that it checks declared product quality through regular laboratory testing. Its company information establishes the supplier’s background, while individual product documents provide the specifications needed to assess a particular grade.
Understanding Chromium(III) Oxide and Its Green Color
Chromium(III) oxide is the chemical basis of the range. Its formula, Cr₂O₃, expresses a ratio of two chromium atoms to three oxygen atoms, and its CAS number is 1308-38-9. The “III” identifies chromium’s +3 oxidation state, which forms part of the substance’s chemical identity.
The International Chemical Safety Card describes chromium(III) oxide as a light-to-dark-green powder that is insoluble in water. ZWUKSO offers the material in a synthetic, finely milled form for pigment applications. In a formulation, these solid particles must be dispersed through the host material, with the finished appearance influenced by the pigment and other ingredients.
Available Grades: GA-U, GA-R, GN, and Other Options
The official product page lists eight grades: GA-U, GA-R, GN, GA, GA-3, GA-6, GA-40, and GA-60. These codes identify the available catalogue options. The page names the grades but does not provide a numerical comparison showing how their properties differ.
GN illustrates why the accompanying documents matter. Its safety data sheet, updated January 7, 2025, lists chromium(III) oxide at 95–100% by weight. That is a declared composition range for this particular product. Comparing shade, particle characteristics, dispersion, and processing performance requires the relevant technical specifications rather than assumptions based on the grade codes alone.
Coloring Strength, Hiding Power, and Dispersion
ZWUKSO describes the CHROMTEX™ range as having good coloring power, high hiding power, and good dispersibility. These terms address different properties. Coloring strength describes how strongly a pigment influences a mixture’s color. Hiding power relates to a coating’s ability to conceal the surface beneath it.
Dispersion involves breaking down pigment agglomerates and distributing the particles throughout a formulation. Uneven dispersion can produce inconsistent color or visible particles. Practical performance depends on the grade, pigment concentration, surrounding ingredients, and processing conditions. Comparisons are therefore most useful when samples are prepared and evaluated under matching conditions.
Uses in Paints, Primers, and Coatings
Paints and coatings are among the applications named in the supplier’s product information. Chrome oxide green provides the green color component in formulations such as primers, coating systems, and fillers. Its influence on the finished appearance depends on both the pigment grade and the surrounding formulation.
Developers can compare dried samples on the intended substrate, examining shade, coverage, smoothness, and consistency. Keeping application thickness and test conditions comparable makes differences between batches or grades easier to assess. The selected binder, other pigments, and additives also contribute to the final finish, making the complete coating formulation the appropriate basis for evaluation.
Coloring Concrete Roof Tiles, Bricks, and Building Materials
ZWUKSO lists concrete roofing products, colored bricks, tiles, and facade mixtures among the range’s construction applications. In cement-based products, manufacturers can incorporate a suitable pigment into the mix to color the material throughout. The pigment then becomes part of the product’s body color.
The finished shade also depends on the cement, aggregates, and formulation. A green pigment can produce different appearances in white and grey cement. Cured samples made from the proposed mix provide a more useful basis for color approval than the dry powder alone. Consistent raw materials and processing conditions help manufacturers maintain appearance between production batches.
Applications in Plastics, Rubber, and Flooring
Plastics, rubber products, and flooring are also named in ZWUKSO’s application list. In these settings, the pigment supplies green color within a compounded or formulated material. Achieving an even appearance requires appropriate distribution of the particles through the polymer, rubber compound, or flooring binder.
Grade selection should account for processing conditions and the intended finished product. Trial samples can be examined for shade uniformity, visible agglomerates, and surface finish. For flooring, evaluating the complete binder-and-filler formulation is especially useful because other ingredients affect the appearance. Testing the actual material provides a clearer assessment than comparing pigment powders by eye.
Uses in Ceramics, Enamel Frits, and Colored Glass
ZWUKSO lists enamel frits and colored glass among the applications for its green pigment range. The underlying compound, chromium(III) oxide, is also used as a ceramic colorant. These applications involve incorporating the coloring material into glass, glaze, or enamel formulations.
Processing conditions matter because the final appearance develops within the surrounding material. Glaze composition, firing temperature, and kiln atmosphere can influence the result. A representative fired or melted sample helps establish the shade and finish achievable with the selected grade. Testing under the intended manufacturing conditions provides a firmer basis for selection than judging the original green powder alone.
Choosing a Grade and Testing Sample Performance
Begin with the intended material and processing conditions, then request technical information for the grade being considered. Catalogue codes alone cannot establish which option will perform best. An approved reference sample provides a target for comparison, while the trial formulation should represent the actual binder, cement, polymer, or glaze system.
Prepare comparative samples using consistent pigment loading, mixing conditions, and application or firing procedures. Examine shade uniformity, dispersion, surface finish, and other relevant performance requirements. Recording the grade, batch number, and test conditions makes comparisons easier to repeat. Small-scale trials help identify a suitable candidate before committing to full production.
Reading Technical Data Sheets and Safety Data Sheets
Technical data sheets and safety data sheets serve different purposes. A TDS describes product specifications and intended applications, potentially including shade, coloring strength, particle characteristics, and processing information. An SDS addresses chemical identity, hazards, exposure controls, handling, storage, and emergency measures.
Both documents should match the selected grade, and their revision dates should be checked. In the standard SDS layout, Sections 1–3 cover identification, hazards, and composition, while Sections 7–8 address handling, storage, and exposure controls. Reading both documents connects the product’s intended performance with the precautions needed for its use.
Dust Control, Protective Equipment, and Safe Handling
Fine pigment dust can irritate the eyes and respiratory tract. The GN safety data sheet calls for adequate ventilation and extraction where powder can become airborne. Handling should minimize dust during opening, weighing, transferring, and mixing, with containers closed when the material is not being used.
Safety glasses, gloves, protective clothing, and any required respiratory protection should follow the current SDS and workplace exposure assessment. Cleanup should prevent further dust dispersal and keep material out of drains and waterways. Wash hands after handling, and keep food and drink away from the work area. These precautions apply alongside the instructions for the specific product supplied.
Packaging, Storage, and Bulk Supply Options
ZWUKSO’s product page lists 25 kg net bags and 1,000 kg net big-bags for its chrome oxide green range. The choice affects how the material is delivered, stored, and transferred into production. When ordering, confirm the grade, packaging format, stock availability, lead time, and delivery arrangements.
For GN, the available safety data sheet recommends keeping the product in its original, tightly closed packaging in a dry, cool, well-ventilated area protected from sunlight. It also specifies separation from incompatible materials and food or drink. Storage and transfer arrangements should follow the current instructions for the particular grade purchased.
Comparing Supplier Quotes and Product Specifications
Compare quotations for the same grade and packaging size using a common price per kilogram. Check how freight, taxes, pallets, insurance, and minimum order quantities affect the delivered cost. Discuss sample availability or trial quantities before committing to a larger purchase.
Then compare the technical documents, including declared composition, shade, coloring strength, and any particle or dispersion data provided. Identify which figures are typical values and which are specified acceptance limits. Request current grade-specific documentation and, where available, batch test results. This connects the quoted price to a defined product and gives purchasing and quality teams a clearer basis for comparison.
