Silicone sealant is an indispensable sealing material in home renovation, used for gap filling, waterproof sealing, and more. However, many homeowners face a common post-construction issue: Why does silicone sealant emit a pungent odor? This unpleasant smell is not only irritating but may also pose health risks. In reality, the odor is closely related to low-molecular-weight substances released during the sealant's curing process. Different types of silicone sealants vary significantly in environmental performance. Today, we explore the reasons behind the persistent pungent odor after sealant application.
First, we need to understand the classification of silicone sealants based on the low-molecular-weight substances released during curing:
-Neutral alkoxy silicone sealant
-Neutral oxime silicone sealant
-Acetic silicone sealant
Origin of the Pungent Odor: The Risks of Oxime and Acetic Silicone Sealant
Oxime Sealants: During curing, these sealants release oxime compounds such as butanone oxime. These volatile compounds have a strong, pungent odor. Prolonged inhalation may irritate the respiratory tract, eyes, and skin. Especially in poorly ventilated indoor spaces, the irritating odor from oxime sealants lingers, negatively impacting occupants' quality of life and health. This conflicts with modern green and healthy living concepts.
Acetic Silicone Sealant: The curing process releases acetic acid compounds, which are highly irritating to the respiratory tract and eyes. Furthermore, acetic acid reacts with alkaline components in building materials (like ceramics and marble) and can corrode metal substrates, compromising renovation quality. Consequently, Acetic Silicone Sealants are unsuitable for whole-house finishing and sealing applications.
The Eco-Friendly Alternative: Advantages of Alkoxy Silicone Sealant
Alkoxy silicone sealants cure through a reaction with atmospheric moisture, releasing alcohol compounds. Compared to the oxime compounds released by oxime sealants, alcohols are significantly more environmentally friendly and have a much milder odor. Alkoxy silicone sealants are free from harmful substances like formaldehyde and benzene, safeguarding indoor environmental health from the source. Whether in high-humidity areas like kitchens and bathrooms or air-quality-sensitive spaces like bedrooms and living rooms, alkoxy silicone sealants deliver excellent sealing performance while protecting your family's health.
