Achieving the deepest black possible is a challenge. In this article, we first analyze the most advanced black pigments in the industry, such as Vantablack and MIT’s Blackest Black, and then focus on specific and technical options for using black pigment in concrete for modern construction.
Advanced Deep Black Pigments
Among the most notable advancements in black pigments are Vantablack and the pigment developed by MIT—revolutionary materials in terms of darkness and light absorption. However, these pigments were primarily designed for space missions and scientific and technological applications.
These materials can absorb more than 99.95% of visible light, eliminating virtually any reflection. They are composed of carbon nanotubes and are not considered traditional pigments but rather advanced coatings that require specific application conditions.
The Deepest Black in the Art World
In the art world, contemporary artist Anish Kapoor obtained exclusive rights to use the Vantablack pigment in his projects, making him the only artist authorized to work with this black pigment.
Vantablack in Architecture
Vantablack was originally developed for space missions and scientific applications, but it also caught the attention of the architectural world. This led to the creation of the Hyundai Pavilion, designed by British architect Asif Khan for the 2018 Winter Olympics in South Korea. This pavilion is coated with Vantablack and is considered the darkest building in the world, creating the illusion of a deep void or a portal to outer space.
Regarding Vantablack’s application in architecture, it is important to note that this material is not a traditional pigment. Its application requires specific conditions and advanced techniques, which significantly limit its use in conventional architectural projects.
Black Pigment in Concrete: Innovation and Limitations
For concrete, there are several black pigment options that vary in intensity, durability, and ease of application. The most commonly used option is iron oxide black (SC Pigments References 51, 53, 55). These pigments are UV-resistant and ensure complete color stability for both interior and exterior applications. Iron oxide pigments are ideal for achieving gray tones, which can be lighter or darker depending on the dosage applied. However, when a project requires a more intense black, this pigment needs to be enhanced with another type of pigment.
To achieve very dark tones in concrete, carbon black can be used—the most intense and opaque black pigment available, capable of producing deep black shades.
The Solution for Deep Black in Concrete
Our Intense Black 5990 pigment is an ultrafine formula that incorporates carbon black, enabling blacks that cannot be achieved with iron oxide pigments. To ensure optimal color results, we recommend prior consultation, as its application may require more precise control to achieve the desired shade.
