SILICONE, which is a partial product of organic silicon. It is mainly divided into deacetic acid type, dealcoholization type, deamination type and deoxime type. The chemical composition is polydimethylsiloxane, and the polymer of silica can be called silicone. Silicone sealant is an ointment-like material that solidifies into a tough, rubber-like solid once exposed to moisture in the air.
- Classification of silicone sealant
One-component and two-component.
One-component silicone sealant is cured by contact with moisture in the air and changes in physical properties;
Two-component means that the silicone sealant is divided into two groups, A and B. Neither group can be cured if it exists alone, but the two groups of glue will solidify once they are mixed.
Commonly seen on the market is single-component silicone sealant. Single-component silicone sealant is divided into acid and neutral according to their properties. Acid silicone sealant is mainly used for general bonding between glass and other building materials. Neutral silicone sealant overcomes the characteristics of acid silicone sealant that corrodes metal materials and reacts with alkaline materials, so it has a wider range of applications and its market price is slightly higher than that of acid silicone sealant. A special type of silicone sealant on the market is silicone structural sealant. Because it is directly used for the metal and glass structure or non-structural bonding assembly of glass curtain walls, the quality requirements and product grade are the highest among glass glues. The market price is also the highest.
- 1. Mainly used for structural or non-structural bonding devices between metal and glass of glass curtain walls.
- 2. It can directly connect glass to the surface of metal components to form a single assembly component, meeting the design requirements of curtain walls with fully or semi-hidden frames.
- 3. Structural bonding and sealing of insulating glass.
