Basic Info

This construction grade iron oxide black colorant is a special inorganic pigment for concrete and building materials, which can provide stable and uniform jet black color for concrete products, bricks, tiles and other building materials. It has excellent alkali resistance, which can adapt to the strong alkaline environment of concrete mixing and solidification, and will not fade or discolor during the service life of building materials. It also has a certain reinforcing effect on concrete, improving the compressive strength and durability of building components, solving the problems of poor color fastness and short service life of general building pigments.

Customer reviews

Michael · Construction Project Manager
The Construction Grade Iron Oxide Black Colorant for Concrete has been a reliable choice for our projects. It provides deep, long-lasting color to concrete surfaces, even under harsh weather conditions. The color doesn't fade over time, and the application process is straightforward. It's a cost-effective solution for enhancing the aesthetic appeal of our structures.

Product Description

Product features:

Compared with ordinary building pigments, this product has high color strength, which can achieve the required black color with less addition amount, reducing the production cost of building materials. It has excellent alkali resistance, light fastness and water resistance, and can maintain stable color for more than 20 years in outdoor building environments. Adding this pigment to concrete can improve the compressive strength of concrete by 3-5%, and improve the freezing-thawing resistance of building components, extending the service life of buildings. The product is packaged in 50kg woven bags with inner PE liner, which is convenient for transportation and construction use.
