feuchteabweisenden

Feuchteabweisend describes the property of a material or surface to repel moisture. This means that liquids, particularly water, are not easily absorbed by or do not penetrate the material. Instead, the liquid tends to bead up and roll off. This characteristic is achieved through various means, often involving the surface properties of the material itself or the application of specific coatings or treatments.

In the context of textiles, feuchteabweisend finishes are common in outerwear, sportswear, and camping gear. These treatments create a barrier that prevents water from soaking into the fabric, keeping the wearer dry. However, it's important to distinguish this from waterproofness. Feuchteabweisend materials may still allow water to pass through under significant pressure or prolonged exposure, whereas waterproof materials are designed to be completely impermeable.

In construction and building materials, feuchteabweisend properties are crucial for preventing water damage, mold growth, and degradation of structures. Sealants, paints, and membranes used on walls, roofs, and foundations often incorporate feuchteabweisend characteristics to protect against rain, humidity, and ground moisture. This helps to maintain the integrity and longevity of buildings. The effectiveness of a feuchteabweisend treatment can be measured by its water contact angle, with higher angles indicating better repulsion.
