Tiivistymiskestävyys

Tiivistymiskestävyys refers to the ability of a material or structure to resist the penetration of moisture in liquid form, such as water. It is a crucial property in various applications, particularly in construction and engineering, where preventing water ingress is essential for durability and performance. Materials with high tiivistymiskestävyys are less likely to absorb water, swell, degrade, or be susceptible to damage from freeze-thaw cycles.

This property is often measured through standardized tests that simulate exposure to water under specific conditions. The performance of a material in terms of tiivistymiskestävyys influences its suitability for use in areas exposed to rain, groundwater, or other sources of liquid moisture. For example, in building envelopes, materials like certain types of membranes, coatings, and sealants are selected for their excellent tiivistymiskestävyys to protect the interior from water damage. Similarly, in marine applications, materials with high resistance to water penetration are vital for the longevity of vessels and offshore structures. The concept is closely related to hydrophobicity and water repellency, but tiivistymiskestävyys specifically addresses the resistance to *penetration* rather than just surface beading.
