Water-repellency

Water-repellency describes the characteristic of a substance, material, or surface that resists the penetration of water. This property is achieved through surface tension and molecular interactions that prevent water molecules from readily spreading or adhering. Water-repellent materials cause water to bead up and roll off, rather than absorb or soak in. The degree of water-repellency can vary, from a slight resistance to complete impermeability, and is crucial in many applications to protect against moisture damage and maintain performance.

Water-repellency meaning with examples

• The durable water-repellency of the tent fabric kept us dry even during a torrential downpour. The special coating on the tent caused the rain to bead up and roll off, protecting the interior from getting wet.
• Our hiking boots feature a water-repellency treatment that effectively prevents water from seeping in. This is crucial for keeping feet dry and comfortable during long treks through wet terrain or puddles.
• The water-repellency of the car's windshield allows for improved visibility in rainy conditions. The coating promotes water beading and run-off, minimizing the need for windshield wipers.
• The water-repellency of the tablecloth meant accidental spills could be wiped away easily. It saved the table from staining and made the cleanup a much quicker process.
