water absorption coefficient

The water absorption coefficient is a measure of how easily a material soaks up water. It indicates the rate at which water penetrates into the material's surface over time. A higher coefficient means the material absorbs water quickly, while a lower value shows it resists water penetration. This property is important for evaluating durability, waterproofing, and suitability for specific uses, such as construction or textiles. Understanding this coefficient helps in selecting materials that meet the needs of a project, ensuring they perform well in environments where water exposure is a concern.
