Coloring Tiles

Colored bricks (such as permeable bricks, bread bricks, pavement bricks, etc.) need to be exposed to outdoor environments for a long time, facing challenges such as sun exposure, rain, freeze-thaw cycles, and alkaline cement environments. Iron Oxide Pigments have the following advantages:

Strong weather resistance: UV resistant, non fading

Good alkali resistance: able to stably exist in cement matrix with high pH value

● Non toxic and environmentally friendly: meets building material safety standards

Rich colors: a complete range of mainstream color schemes including red, yellow, black, brown, green (composite), etc

Low cost, strong coloring power: suitable for large-scale industrial production

1. Light resistance: ≥ Grade 7 (ISO 105-B02)

2. Alkali resistance: Soak in NaOH solution with pH=12.5 for 7 days without significant discoloration

3. Dispersion: Uniform and non clumping in cement slurry

4. Impact on strength: When the dosage is ≤ 10%, the 28 day compressive strength loss is ≤ 5%

5. Environmental friendliness: The content of heavy metals (Pb, Cd, Cr ⁶⁺, etc.) complies with GB/T 25821 or EN 12878 standards
