Acetoxy-curing silicone, also known as acetoxy silicone, is a proven type of silicone sealant widely used for standard applications in sanitary and construction areas. During curing, acetic acid is released, which causes the characteristic vinegar-like smell. This curing system has been successfully used for many years and is known for its excellent adhesion to smooth, non-porous surfaces. Our premium bathroom silicone sealant belongs to this type of silicone.
Acetoxy-curing silicone remains permanently elastic, is waterproof and cures relatively quickly. Due to its chemical properties, it offers reliable adhesion to typical sanitary substrates.
Acetoxy silicone adheres particularly well to glass, ceramic and enamel. For this reason, it is commonly used as sanitary silicone in bathrooms, showers or for glazing applications. For classic sanitary joints on non-sensitive substrates, acetoxy-curing silicone is a proven solution.
During the curing process, acetic acid is released, which causes the characteristic vinegar-like smell. This odour disappears completely once the silicone has fully cured. The vinegar smell is a clear indicator of this type of silicone and distinguishes it from neutral-curing variants.
Acetoxy-curing silicone is not suitable for all substrates. On sensitive materials such as natural stone or certain metals, it may cause discolouration or material reactions. In these cases, neutral-curing silicone should be used, as it offers higher material compatibility.
Acetoxy-curing silicone is mainly suitable for sanitary joints and applications on smooth, non-sensitive surfaces. Proper surface preparation is essential to ensure optimal adhesion. When selecting the product, make sure that the silicone is suitable for the intended application, such as bathrooms or showers.
You can find acrylic sealants and other types of silicone in the category silicone caulk.
