what is silicone sealant

Silicone sealant is a kind of ointment, which will solidify into a tough rubber-like solid material once it comes into contact with moisture in the air. It is mainly divided into deacetic acid type, dealcohol type, deammoniation type, and deacrylic type. Silicone sealant is commonly known as glass sealant because it is often used for glass bonding and sealing. Single-component silicone glass glue is a kind of ointment-like material, which will solidify into a tough rubber-like solid material once it comes into contact with moisture in the air.

Silicone glass sealant has strong adhesion and high tensile strength. It is also weather-resistant, vibration-resistant, moisture-proof, odor-resistant, and adaptable to large changes in temperature. In addition, its wide applicability can achieve bonding between most building materials, so its application value is very large.

According to properties
Single-component silicone sealant is divided into acid glue and neutral glue according to its properties.
Acid silicone sealant is mainly used for general bonding between glass and other building materials. Neutral sealant overcomes the characteristics of acid glue corroding metal materials and reacting with alkaline materials, so it has a wider range of applications and its market price is slightly higher than that of acid glue.

A relatively special type of silicone sealant on the market is silicone structural sealant. Because it is directly used for metal and glass structures or non-structural bonding assembly of glass curtain walls, its quality requirements and product grade are the highest among glass silicon sealant, and its market price is also the highest.
