Chemical Resistant Pigments Powder

Specialist in High-Stability Pigment Chemistry

Deqing Demi Pigment Technology Co., Ltd. provides the global market with pigments designed for the most challenging chemical environments. Our expertise in synthesis and calcination allows us to produce inorganic powders that outperform organic alternatives in terms of chemical durability. We serve manufacturers of industrial plastics, specialized coatings, and laboratory equipment, providing them with the coloring solutions needed for chemically sensitive applications.

Chemically Demanding Application Areas

• Laboratory Furniture: Pigmentation for acid-resistant work surfaces and storage cabinets.
• Industrial Floor Linings: Coatings for battery rooms and chemical processing areas.
• Food Processing Equipment: Colorants for materials exposed to acidic foods and caustic cleaning agents.
• Fertilizer Industry: Pigmentation for storage and handling equipment exposed to corrosive chemicals.

Chemical Resistance Technical Table

Core Chemical Characteristics

• Inert Crystalline Structure: Resists the breaking of chemical bonds when exposed to strong electrolytes.
• Zero Migration: Does not dissolve in plasticizers or solvents, preventing the contamination of adjacent materials.
• Low Reactive Impurities: Minimized levels of soluble metals prevent the pigment from acting as a catalyst for chemical reactions.
• Thermal Stability: Retains chemical resistance even when the temperature of the chemical environment increases.

• Q: Can these pigments be used for coloring chemical storage tanks?

  A: Yes, their inherent resistance to a wide range of chemicals makes them suitable for integral coloring or surface coatings of fiberglass and steel storage tanks.

• Q: Do these pigments react with oxidizers?

  A: Our inorganic iron oxides are in their highest oxidation state and are generally very stable toward common industrial oxidizing agents.

Verification of Resistance

We subject our chemical-resistant grades to immersion tests in various industrial reagents to verify their performance. This data is available to help our customers select the correct grade for their specific chemical environment.

Custom Chemical Compatibility: If a client has a unique chemical exposure requirement (e.g., a specific proprietary solvent), we can conduct a customized compatibility test in our lab to verify the pigment's performance.

Analyzing Surface Integrity after Exposure

The science of chemical resistance is measured through the change in the surface morphology and color. We use Glossmeters and Colorimeters to detect any degradation of the binder-pigment interface after chemical exposure. A stable pigment will show a Delta E of less than 0.5 after standard spot tests. We also use microscopic analysis to ensure that no "micro-pitting" or surface erosion has occurred, ensuring that the colored surface remains easy to clean and maintains its protective function over time.
