vedenpitävyysominaisuuksia
Vedenpitävyys, or water impermeability, is the ability of a material or structure to prevent the passage of water under specified conditions. It is a critical property for protecting people, goods, and environments from moisture damage and is a key consideration in construction, textiles, packaging, and electronics.
The terms waterproof, water-resistant, and watertight describe degrees of protection. Waterproof typically indicates protection against water
Testing and standards vary by application. In electronics, ingress protection (IP) ratings describe protection against solids
Materials and methods to achieve vedienpitävyys include waterproof membranes (bituminous or polymeric), sealants and coatings, cladding
Applications range from roofs, basements, and bathrooms in construction to outdoor clothing, tents, and electronics housings.
