Infrared reflective pigment

What is Infrared Reflective Pigment?

Infrared reflective pigment is a functional material designed to reflect near-infrared (NIR) radiation while maintaining desired visible color appearance. It is widely used in thermal management coatings to reduce heat buildup on surfaces exposed to sunlight.

Unlike traditional pigments that mainly control visible color, infrared reflective pigments focus on controlling solar energy absorption, especially in the infrared spectrum that contributes most to heat generation.

How It Works

Infrared reflective pigments work by selectively reflecting infrared wavelengths (typically 700–2500 nm) while allowing visible light to pass or be selectively absorbed depending on formulation. This helps reduce surface temperature without significantly altering color design.
