The precise control of light interaction is paramount in the development of advanced coatings. Near-infrared (NIR) absorbers are specialized additives that play a crucial role in applications requiring selective light manipulation, offering benefits from thermal management to specialized optical functions. As a manufacturer of these high-performance materials, we aim to illuminate their importance and accessibility.

The Functionality of Near-Infrared Absorbers in Coatings

NIR absorbers are designed to absorb light within the near-infrared spectrum (approximately 700 nm to 2500 nm). This capability is leveraged in several key areas:

  • Thermal Management: In coatings applied to surfaces exposed to sunlight, NIR absorbers can block a significant portion of the heat-generating infrared radiation, helping to maintain cooler surface temperatures. This is valuable for architectural coatings, automotive finishes, and protective films.
  • Optical Filtering: For specialized optical coatings, such as those used in sensors, cameras, or displays, precise control over the infrared spectrum is essential. NIR absorbers can be formulated to act as filters, allowing visible light while blocking unwanted IR wavelengths.
  • Antistatic Properties: Some NIR-absorbing materials, often based on metal oxides like Antimony Tin Oxide (ATO) or Indium Tin Oxide (ITO), also possess inherent conductive properties that can impart antistatic functionality to coatings, preventing static electricity buildup.

Product Spotlight: Specific Grades for Coating Applications

We offer a range of infrared absorbers suitable for various coating formulations:

  • IRA SYP 02: Described as a 'Light Green Powder' with a specific surface area of 30-50 m²/g and particle sizes of 5-10 nm, this product is well-suited for solar films and antistatic coatings, indicating excellent dispersibility in coating matrices.
  • IRA OYP 01: As a 'Yellow green powder' with a larger particle size range (10-100 nm), this variant may offer different absorption profiles and performance characteristics beneficial for transparent conductive coatings or radiation protection applications.
  • IRA CD 04 & IRA CD 05: These 'Dark Brown Powder' and 'Dark Green Powder' respectively, with specific absorption peaks around 1080-1090 nm and 895-905 nm, are excellent candidates for applications requiring strong infrared absorption, potentially for specialized optical filters or infrared dyes used in coatings.
