Silicone sealant has been widely used in curtain wall, doors and Windows, insulating glass and interior decoration and other architectural fields, play the role of bonding and sealing. Building silicone sealant according to the use, can be roughly divided into the following five categories: silicone structural sealant, silicone weather sealant, ordinary silicone sealant, hollow glass with two silicone sealant, special purpose silicone sealant.

1.silicone structure sealant

Uses: mainly used for glass and aluminum frame structure bonding, also used for hidden frame curtain wall insulating glass two sealing.
Features: bear wind load, gravity load, high requirements on strength, aging resistance, elasticity has certain requirements.

2.silicone weather resistant sealant

Purpose: curtain wall joint sealing function, to ensure the curtain wall air tightness, water tightness and other properties.
Features: need to bear large joint width change, elasticity (displacement capacity), high aging resistance, does not require strength, high modulus, low modulus can be.

3. ordinary silicone sealant

Application: door and window joints, wall sealing and other positions.
Features: to withstand the change of joint width, there is a certain displacement capacity requirements, do not require strength.

4. hollow glass with two silicone sealant

Purpose: double sealing of insulating glass to ensure the structure stability of insulating glass.
Features: high modulus, not too soft, some have structural requirements.

5. special use silicone sealant

Application: used for sealing joints with special requirements, such as fireproof, mildew proof etc.
Features: Need to have some special performance (such as mildew, fire, etc.).
