KondensationCureSilikone

KondensationCureSilikone, also known as RTV-1 (Room Temperature Vulcanizing - 1 component) silicones, are a type of silicone rubber sealant that cures through a chemical reaction with atmospheric moisture. These sealants are typically supplied as a paste or liquid and, upon exposure to humidity, undergo a condensation reaction that crosslinks the silicone polymer chains. This process transforms the uncured material into a flexible, durable, and elastic rubber.

The curing mechanism of kondensationCureSilikone involves the release of a byproduct during the reaction. The type of byproduct released depends on the specific formulation. Common byproducts include acetic acid (producing a vinegar-like odor during curing), oximes, or alcohols. This byproduct release is a key characteristic that distinguishes them from other silicone cure types.

KondensationCureSilikone are widely used in various applications due to their ease of use, good adhesion to many substrates, and resistance to temperature extremes, UV radiation, and weathering. They are commonly found in construction for sealing joints and gaps, in automotive applications for gaskets and sealing, and in electronic encapsulation. The curing time is dependent on factors such as temperature, humidity, and the thickness of the applied sealant. Over time, the uncured material in the container can also begin to cure if exposed to ambient moisture, necessitating proper storage.
