Sun Chemical’s Functional Black Pigments for Solar Heat Management Applications

Sun Chemical's functional black pigments can be used to formulate systems that reflect sun radiation for effective solar heat management.

With solutions for solar heat management, Sun Chemical, a leader in the pigment industry, empowers modern design possibilities. While dark surfaces with standard black pigments intensively absorb solar energy and convert it to heat, functional black pigments can be used to formulate systems that reflect sun radiation. In this post, we delve into the utilization and the benefits of functional black in various solar heat management applications.

The functionality of solar heat management pigments

While conventional black pigments absorb the energy of sunlight and turn it into heat, functional black pigments ensure cooler surfaces by significantly reducing energy absorption of sunlight. Being transparent to near infrared radiation (NIR) pigments of the SpectrasenseTM family enable sun radiation to pass through to a reflective surface, while Sicopal® pigments and their related pigment preparations Xfast® and Luconyl® NG bring NIR reflective properties into a coating system.

Application examples

Roof tiles

Functional roof tiles reflect more infrared light than traditional roof tiles. The roof stays cooler and also cools the surrounding air, which leads to an improvement of the air in the living space and increases the lifetime of the tiles.

Exterior insulation finishing systems

Especially for darker surface colors, surface temperatures can be reduced to avoid cracking of the plaster and deformation of insulation materials.

Window frames

For bigger sized windows with dark coated window frames it is beneficial to reduce the surface temperature to achieve a better structural integrity.

Entrance doors

Coatings of entrance doors with functional pigments may reduce the temperature of the entrance hall, help to maintain structural integrity, and increase the durability of the door material.

Garage doors

Cool pigments reduce the heat absorption, may prevent warping and breaking, and extend the durability of the garage doors.

Automotive exterior

Keeping the surface of cars cooler may reduce energy consumption of air conditioning, enhances comfort, and maintains constructional strength and surface material durability when exposed to the sun.

Automotive interior

Black dashboards, instrument panels, seats, arm rests, steering wheels in a car grow unbearably hot in the sun which the usage of non-absorbing pigments may prevent. In addition to increasing the personal comfort, a reduced heat-up prevents materials getting brittle, ensures dimensional stability, avoids material degradation, and saves energy by reducing need for air conditioning.

Asphalt coatings

In asphalt coatings, functional black pigments and pigment preparations support cool city projects fighting the urban heat island effect.
