Five types of sealant introduction!

 Sealant can be roughly divided into the following five categories according to the application: silicone structural sealant, silicone weatherproof sealant, ordinary silicone sealant, two-way silicone sealant for insulating glass, special purpose silicone Sealant.

First, silicone structural sealant

Uses: Mainly used for the structural bonding of glass and aluminum sub-frames , and also for the two-way sealing of hollow glass in hidden frame curtain wall.

Features: Withstand wind load, gravity load, high requirements for strength and aging resistance, and certain requirements for elasticity.

Second, silicone weatherproof sealant

Uses: Seam sealing function, to ensure air tightness, water tightness and other properties.

Features: It needs to withstand the wide and narrow seam change, high elasticity (displacement ability), high aging resistance requirements, no strength, high modulus, low modulus.

Third, ordinary silicone sealant

Uses: Door and window joints, external wall caulking and other location seals.

Features: Withstand wide and narrow seam changes, have certain displacement capacity requirements, and do not require strength.

4. Two-way silicone sealant for insulating glass

Uses: Two-way sealing of insulating glass to ensure the stability of the insulating glass structure .

Features: high modulus, not too soft, some have structural requirements.

Five, special purpose silicone sealant

Uses: Used for joint sealing with special requirements, such as fire protection, mildew proof, etc.

Features: Need to have some special properties (such as mildew, fire, etc.).
