Suberstrate:Selected natural mineral materials,which have a certain hardness and adsorption capacity but no crystals.


Coating:Inorganic pigments are infiltrated into the substrate through patented technology,significantly improving the color fastness of the colored sand.


Protective layer:Special nanomaterials are applied for surface wrapping to enhance the color and antibacterial properties of the colored sand,greatly enhancing its weather resistance and insulation effect.At the same time,it also adds an auxiliary role in improving the color fastness of the colored sand.
