Overview
Pigment Grade Chrome Oxide Green is a high-performance inorganic pigment derived from chromium(III) oxide. It is valued for its vibrant green hue, exceptional durability, and resistance to environmental factors. Unlike organic pigments, it does not fade under UV exposure or degrade in harsh chemical environments, making it ideal for long-lasting applications. This pigment is manufactured through high-temperature calcination processes, ensuring consistent quality and color stability. Its non-toxic nature and compliance with international safety standards further enhance its suitability for industrial and consumer applications, including coatings, plastics, and construction materials.
Physical and Chemical Properties
Chrome Oxide Green exhibits remarkable physical and chemical stability. It is insoluble in water, acids, and alkalis, which contributes to its longevity in outdoor and chemically aggressive environments. The pigment has a high melting point of 2435°C, making it suitable for high-temperature applications such as refractory materials. Its density of 5.22 g/cm³ and fine particle size ensure excellent coverage and opacity. The pigment's chemical inertness prevents reactions with other materials, maintaining color integrity over time. These properties make it a preferred choice for applications requiring durability and resistance to weathering.
Main Applications
Pigment Grade Chrome Oxide Green is extensively used in the coatings industry for architectural and industrial paints, providing long-lasting color and protection. In plastics, it is employed for coloring products ranging from automotive parts to consumer goods, offering UV resistance and thermal stability. The ceramic industry utilizes this pigment for glazes and decorative tiles, where high-temperature firing is required. Additionally, it is used in inks, construction materials like concrete and mortar, and even in military applications for camouflage due to its infrared reflectance properties.
Safety and Storage
While Chrome Oxide Green is generally non-toxic, precautions should be taken to avoid inhalation of dust particles, which can cause respiratory irritation. Proper personal protective equipment (PPE), such as masks and gloves, is recommended during handling. Storage conditions are critical to maintaining the pigment's quality. It should be kept in a dry, cool environment, away from moisture and incompatible materials. Sealed containers are ideal to prevent contamination and ensure long-term stability.
B2B Procurement Guide
When procuring Pigment Grade Chrome Oxide Green, B2B buyers should prioritize suppliers who provide detailed specifications, including CAS number, purity levels, and particle size distribution. These factors directly impact the pigment's performance in specific applications. Buyers should also consider the supplier's reputation, certifications, and ability to provide consistent quality. Bulk purchasing may offer cost advantages, but it's essential to verify storage capabilities to prevent degradation. Sampling and testing before large-scale orders are recommended to ensure compatibility with intended uses.
