We know that architectural Silicone Adhesive plays a pivotal role in the construction field of curtain wall, doors and Windows, insulating glass and interior decoration. When purchasing or selecting silicone glue, we must know where different types of sealant are suitable for, are there any concerns? The industry believes that according to the use of sealant can be roughly divided into the following five categories: silicone Structural Sealant, silicone weather resistant sealant, ordinary Silicone Sealant, insulating glass with second silicone sealant, special purpose silicone sealant. Different types of silicone sealant have different characteristics and different uses. 1, silicone structural sealant Usage: Mainly used for the structural bonding of glass and aluminum sub-frame, and also used for the second seal of hollow glass of hidden frame curtain wall. Features: withstand wind load, gravity load, high requirements for strength, aging resistance, elasticity has certain requirements. 2, silicone weather resistant sealant Application: joint sealing function to ensure air tightness, water tightness and other properties. Features: need to withstand larger joint width changes, elasticity (displacement capacity), high aging resistance requirements, do not require strength, high modulus, low modulus can be. 
Local profile 3, ordinary silicone sealant Uses: door and window joints, external wall caulking and other position sealing. Features: Withstand the width of the joint changes, there is a certain displacement capacity requirements, do not require strength. 
House doors and Windows 4, insulating glass with second silicone sealant Use: insulating glass two seal, to ensure the stability of the insulating glass structure. Features: High modulus, not too soft, some have structural requirements. 
Figure 3: Insulating glass 5, special purpose silicone sealant Uses: Used for joint sealing with special requirements, such as fire, mildew and so on. Features: Need to have a special performance (such as mildew, fire, etc.). 
Curtain wall fireproof partition sealant must have fireproof performance 
Kitchen, bathroom joint sealant should have mildew resistance The adhesive sealing of different substrates should be correctly selected according to its use characteristics. Different uses of silicone sealant have their own different performance characteristics. In general, they cannot be used in place of each other. For example, using weatherproof sealant instead of structural sealant, using door and window sealant instead of weatherproof sealant, etc., using the wrong sealant may lead to serious quality accidents and safety accidents in the project. Many people want to ask: There is a small gap between the window and the wall, what glue is used to fill it? What is the difference between civil glue and engineering glue? The right choice is: small gaps between doors and Windows and external walls can be filled with Neutral Silicone Sealant, which is also the reason why neutral silicone sealant is more common in civil rubber. In simple terms, civil glue generally refers to the doors and Windows glue and home decoration glue used by ordinary residents; Engineering glue generally refers to the glue used in large building curtain walls and doors and Windows. The performance of civil adhesive is lower than that of engineering adhesive, and it should not be used in engineering in a large area.
