How to use hydrophilic in a sentence. Hydrophilic Hydrophilic means having an affinity or attraction towards water molecules, allowing the substance to readily absorb or interact with water, often leading to increased solubility or dispersibility in aqueous environments. In contrast, hydrophobic materials, or "water-fearing," do not dissolve or interact well with water, leading to distinct behaviors such as water beading on their surfaces. They have positive or negative charges or partial charges. Both types can be used to stop water in concrete crack repair, but hydrophobic systems are best suited for permanent repair of most leaking basement cracks unless there are structural issues (where epoxies coupled with carbon fiber itions on site (e. Once in contact with water, it expands and cures to a closed-cell, flexible foam.
