Functional Paint Additive to Prolong Solar Reflectance
A novel functional additive has been developed for use on solar reflective paints to improve dirt pick-up resistance, enhancing overall longevity and effectiveness.
Technology overview
Solar reflective paints are widely used on exterior walls to reduce the interior temperature of buildings, save energy costs, and decrease the carbon footprint. However, dirt accumulation reduces their efficiency and lifespan. To address this issue, a novel functional additive has been developed. The dirt pick-up resistance (DPUR) improves when the resulting additive is incorporated into a paint post-production. This enhances overall longevity and effectiveness while maintaining paint properties, such as consistency and opacity.
Technology features
The functional additive seamlessly mixes with normal paint via post-addition, preserving essential properties like consistency and opacity
Offers commercial solar reflective paint manufacturers a post-addition route to enhance DPUR properties and extend solar reflectance effects without altering fundamental paint properties
Enables manufacturers to improve paint durability and solar reflectance without compromising underlying paint integrity
Potential applications
Interior and exterior wall paints and functional coatings
Construction, automotive, and infrastructure
Benefits
Unlike typical coating formulations with DPUR properties, the technology introduces a functional additive
No reformulation of the existing commercial solar reflective paint
Enhances existing commercial solar reflective paints' DPUR and prolonged solar reflectance
Commercialisation
The technology is available for licensing and deployment.
