neutralkovettuvia

Neutralkovettuvia, a term derived from Finnish, refers to materials that undergo a curing process initiated by neutral conditions, typically involving ambient temperature and humidity, without the need for external heat, UV light, or specific catalysts. This type of curing mechanism is characteristic of certain adhesive and sealant formulations. The curing process relies on chemical reactions that are activated by the presence of water molecules or by reactions with atmospheric moisture.

These materials are often based on silane-terminated polymers, such as silane-terminated polyethers (STP) or silane-terminated polyurethanes (SPUR). Upon exposure to moisture from the air, the silane groups on the polymer chains react, forming cross-links between the polymer molecules. This cross-linking process transforms the liquid or paste-like material into a solid, elastic rubber. The rate of curing is influenced by factors like temperature, relative humidity, and the thickness of the applied material.

Neutralkovettuvia are valued for their ease of application and their ability to cure at room temperature, which makes them suitable for a wide range of applications where heat or UV exposure might damage the substrate or be impractical. Common uses include sealing and bonding in construction, automotive manufacturing, and general assembly. They often exhibit good adhesion to various substrates, including plastics, metals, and glass, and can provide durable, weather-resistant seals. Their neutral curing mechanism also means they typically do not release strong odors or corrosive byproducts during the curing process.
