Key Performance Advantages

Selecting the right colorant is vital for the longevity of the final product. Pigment Red 176 offers several distinct advantages over standard alternatives:

  • Exceptional weatherfastness ensures color retention in exterior applications exposed to UV radiation.
  • High heat stability allows for processing in thermoplastics without significant shade deviation.
  • Superior solvent resistance prevents bleeding or migration in coating systems.
  • Consistent particle size distribution facilitates smooth dispersion and high gloss finishes.
  • Compliance with global regulatory standards for industrial chemical safety.

Industrial Applications

This specialty chemical is versatile and widely utilized across multiple sectors. Its primary use case involves high-grade exterior paints where durability is paramount. Automotive manufacturers rely on this pigment for original equipment manufacturer (OEM) finishes as well as repair paints that must match existing colors precisely. Beyond coatings, it is extensively used in the plastics industry for coloring engineering polymers that require thermal stability during molding.

In addition to automotive and plastic applications, the pigment is suitable for high-quality printing inks and rubber products. The robust chemical structure ensures that the color remains vibrant even when subjected to mechanical stress or chemical exposure. Formulators appreciate its reliability when developing products intended for harsh outdoor environments.

Quality Assurance and Packaging

We maintain a rigorous quality management system to ensure every shipment meets the specified purity of greater than 99.0 percent. Each batch is accompanied by a Certificate of Analysis (COA) detailing test results for identity, purity, and physical properties. The product is packaged in 25kg drums designed to protect the material from moisture and contamination during transit.

Proper storage is essential to maintain product integrity. We recommend storing the pigment in a tightly closed container within a cool, dry, and well-ventilated area. It should be kept away from incompatible substances and sources of ignition. By adhering to these storage guidelines, manufacturers can ensure the material remains in optimal condition until it is ready for use in production processes.
