Functional Paint Additive to Prolong Solar Reflectance of Cooling Paint

With rising global temperatures, the demand for energy-efficient cooling solutions is becoming increasingly urgent, particularly in tropical regions. Conventional cooling solutions such as air-conditioning and mechanical ventilation not only consume large amounts of electricity also emit greenhouse gases, further accelerating climate change.

Solar reflective paints offer a sustainable solution by reducing heat absorption in buildings, thereby lowering indoor temperatures, cutting energy costs, and decreasing carbon footprint. However, their performance declines over time due to dirt accumulation, which reduces effectiveness and shortens the coating’s lifespan.

To address this challenge, the technology owner has developed a novel functional additive that significantly improves the dirt pick-up resistance (DPUR) of solar reflective paints. By post-production incorporation into the painting, the additive enhances overall effectiveness and longevity while maintaining essential painting properties such as consistency and opacity. This solution extending painting’s solar reflectance by up to 6 times longer than traditional paintings, significantly reducing building cooling loads and lowering maintenance.

The technology owner is actively seeking collaborations with relevant industrial partners to explore IP licensing opportunities.
