Acetoxy silicone refers to a category of one-component, moisture-curing silicone sealants that form flexible, durable elastomeric seals by reacting with atmospheric humidity and releasing acetic acid during cure, which gives a characteristic vinegar-like odor. These sealants are prized for their rapid skin-over and full cure, strong adhesion to non-porous substrates such as glass, ceramics, metals and glazed surfaces, and excellent resistance to water, weathering, UV exposure and temperature extremes, making them suitable for a wide range of general-purpose sealing and bonding tasks in construction, sanitary and industrial applications.
