Pigment Brown 25 (PB25) is an inorganic brown pigment, typically based on mixed metal oxides, offering stable color performance, good opacity, and excellent resistance to light and weathering.
Pigment Brown 25 is widely used in industrial coatings, construction materials, and general-purpose coloring applications where durability, heat stability, and outdoor resistance are more important than high chroma or brightness.
Due to its inorganic nature, PB25 provides consistent performance across demanding environments, making it suitable for long-term use in exterior and industrial systems.
PBr25 – DuraPaint®6925-1 ⬇️TDS
It provides a neutral brown shade with good gloss development and stable color performance, suitable for industrial coating applications.

Pigment Brown 25 is commonly used in applications that require stable brown coloration combined with mechanical and environmental durability:
Industrial and protective coatings
Architectural and exterior coatings
Anti-corrosion primers and metal coatings
Concrete, cement, and construction materials
Plastic products with moderate to high processing temperatures
These applications benefit from PB25’s inorganic structure, which supports consistent color retention and resistance to environmental stress.
Pigment Brown 25 exhibits excellent resistance to UV exposure and weathering, making it suitable for outdoor coatings, construction materials, and long-term exterior use.
PB25 maintains color integrity under elevated processing and service temperatures, which is especially important in industrial coatings and certain plastic applications.
The pigment provides reliable opacity, enabling effective coverage in coatings, concrete, and molded products where uniform coloration is required.
Pigment Brown 25 demonstrates strong resistance to common chemicals and solvents, supporting stable performance in industrial environments and protective coating systems.
Despite its stable performance, Pigment Brown 25 has certain limitations that should be considered during formulation and product selection:
Lower Color Strength Compared to Organic Pigments
PB25 generally offers lower tinting strength than organic brown pigments, which may require higher pigment loading to achieve deep shades.
Limited Shade Brightness
As an inorganic pigment, Pigment Brown 25 produces more muted, earthy brown tones and is not suitable for applications requiring high chroma or vivid coloration.
Dispersion Requirements
Due to its inorganic particle structure, PB25 may require sufficient dispersion energy to achieve optimal color uniformity, especially in coatings and plastics.
Understanding these limitations helps buyers select Pigment Brown 25 appropriately based on performance priorities rather than appearance alone.
Pigment Brown 25 is recommended when buyers prioritize:
Long-term durability over color brightness
Outdoor or industrial exposure conditions
Heat resistance and weather stability
Cost-effective inorganic pigment solutions
For applications where high color strength, transparency, or decorative brightness is required, organic brown pigments or blended systems may be more suitable alternatives.
When selecting PB25, buyers should consider processing temperature, dispersion method, and end-use environment to ensure optimal performance.

Pigment Brown 25 is mainly used in industrial and protective coatings, architectural coatings, construction materials, concrete products, and certain plastic applications requiring durability and heat resistance.
Yes. Pigment Brown 25 offers excellent lightfastness and weather resistance, making it suitable for long-term outdoor and exterior applications.
Pigment Brown 25 can be used in plastics with moderate to high processing temperatures. Proper dispersion is important to achieve uniform coloration.
PB25 provides good opacity but generally lower color strength compared to organic pigments. Higher pigment loading may be required for deeper shades.
Depending on performance requirements, alternatives may include organic brown pigments for higher chroma, or other inorganic pigments when specific shade or regulatory needs apply.
