Fluidimpervious
Fluidimpervious refers to a property of materials or surfaces that resist or prevent the passage of liquids under defined conditions. The term is used in specifications to indicate that a product will not allow a liquid to permeate, seep, or leak through it, often under pressure, immersion, or other stressors. It can apply to coatings, films, fabrics, membranes, and engineered composites, and is common in contexts such as protective clothing, medical devices, packaging, and building or electronic enclosures.
Materials described as fluidimpervious achieve this behavior through a combination of low porosity, dense microstructure, chemical
Testing for fluidimperviousness typically involves controlled liquid exposure to a sample and monitoring for breakthrough or
Limitations include the specificity of the impermeability to certain fluids and conditions. A material that is
