MIL-PRF-85285E SRC Solar Reflective Coating
Cuts Heat. Not Light.
MIL-PRF-85285E SRC is an advanced Solar Reflective Coating engineered to reduce heat build-up caused by Near Infrared (NIR) radiation while maintaining visible light transmission.
Unlike conventional coatings that block both heat and light, MIL-PRF-85285E SRC selectively reflects heat-carrying infrared radiation while allowing visible light to pass through. The result is lower internal temperatures, improved equipment reliability, reduced thermal stress, and enhanced operational performance in demanding environments.
Developed using aerospace-grade polyurethane technology, the coating is ideal for defence platforms, aviation systems, radars, drones, electronic enclosures, and high-performance industrial applications.
The Problem Isn't Sunlight. It's What You Can't See.
Most conventional coatings treat sunlight as a single source of energy.
However, the majority of thermal loading is caused by Near Infrared Radiation (NIR), the invisible component of sunlight responsible for heat generation.
As equipment and structures absorb infrared energy, internal temperatures rise, resulting in:
MIL-PRF-85285E SRC addresses the real source of the problem by reflecting heat-carrying infrared radiation before it can be absorbed.
Advanced NIR Heat Reflecting Technology
MIL-PRF-85285E SRC is specifically engineered to:
The coating helps create cooler operating conditions without sacrificing visibility or functional performance.
