Aqueous composition for rendering a substrate hydrophobic

摘要

A substrate treatment method for imparting hydrophobicity to a substrate or for rendering the substrate hydrophobic. This method includes the step of treating an agricultural soil substrate by applying an aqueous solution that preferably includes a mixture of sodium and/or potassium methylsiliconate and sodium and/or potassium silicate. The method imparts hydrophobicity to the substrate and renders it hydrophobic.
