fuktsensitive

Fuktsensitive is an adjective used to describe materials, components, or systems whose performance or reliability is affected by moisture in the environment. The term is often used in technical contexts to indicate sensitivity to humidity, water ingress, or condensation.

Moisture sensitivity can arise from chemical reactions, swelling, diffusion, or corrosion. Common fukt-sensitive items include polymers and coatings that absorb water, metals prone to corrosion, wood, textiles, and many electronic components with imperfect seals. Water exposure can change mechanical properties, electrical resistance, or adhesion, and may accelerate aging or lead to failure under operating conditions.

Assessment typically involves humidity or damp-heat testing, humidity storage, or moisture sorption measurements. Standards for electronics and materials reliability provide procedures for damp-heat exposure and condensation testing to evaluate fuktsensitivity.

Mitigation strategies include moisture barriers, conformal coatings, desiccants, proper sealing, and careful material selection with low moisture uptake. Designing for environmental control, robust packaging, and appropriate quality assurance can reduce the risk of moisture-related degradation in fuktsensitive products.

The term is not widely standardized in international nomenclature and is more common in language-specific technical literature and product documentation. It is closely related to concepts such as moisture sensitivity, hygroscopicity, and moisture ingress susceptibility.
