Introduction of insulating glass sealant

Introduction of insulating glass sealant

Insulating glass sealant is a new generation of green environmental protection sealing material born under the national policy on high efficiency, energy saving, sealing and environmental protection of construction projects.
Insulating glass sealants can be divided into two categories: thermoplastic and thermosetting.
Insulating glass sealants belonging to the thermoplastic category include hot-melt butyl rubber, polyisobutylene rubber and comfort rubber strips.
Insulating glass sealants belonging to the thermosetting category include silicone glue, polyurethane glue and polysulfide glue.
Generally speaking, thermoplastics are mostly used for the first seal, and thermosetting adhesives are mostly used for the second seal, that is, structural seals.

Hollow glass sealant structure

The hollow glass structure generally refers to the sealing structure of the hollow glass. There are two main sealing structures for insulating glass: single-channel sealing and double-channel sealing. The single-pass sealing structure means that the hollow glass structure only has one layer of glue, and you can choose polysulfide glue, hot melt butyl glue or comfort glue. The double-pass seal structure refers to the hollow glass structure with two layers of glue, usually polyisobutylene glue is used as the first seal, and structural glue such as polysulfide glue or silicone glue is used as the second seal. Generally speaking, in a dual-channel sealing system, the glue used for the first seal has a high water vapor transmission rate but poor structure, while the second sealant has a high structural performance and poor water vapor transmission rate.

What users say about JOINTAS

The sealant has a fine texture and no bubbles, and the taste is very small. It is very convenient to use and dries very fast. The instructions are very detailed. The effect is good after using it.


The packaging of this product is very good, very strict, and the design is very scientific.


The product I bought is really good. The other ones I bought before have a lot of particles in it. They are not smooth to the touch. I don’t know how to use it, and the beauty stitches I bought make it. I really don’t have to say.


The effect is very good! The smell is very small, almost no smell during construction.


The quality is very good. I made it at home by myself. It's okay. The effect is good. The quality is indeed better than the price bought in other stores.


The smell is very small, the gel is translucent, it is smooth to use, and it dries quickly. The anti-mildew effect needs time to test.

a) Butyl rubber has quality problems or is incompatible with silicone rubber b) Insulating glass is filled with mineral oil with a second sealant c) Contact with oil-extended glue, such as weatherproof glue for curtain wall joints or sealant on doors and windows d) Other factors such as desiccant or processing technology

In order to ensure the quality of the glue injection process, it is recommended to make the following preparations before using the second insulating glass sealant: a: Requirements for use environment and maintenance environment: The injection area of ​​the second insulating glass sealant should be clean, dust-free, and ventilated. The temperature should be kept at 10℃-40℃, and the relative humidity should be 40%-80%. The temperature should not be lower than 10℃. When the storage temperature in winter is relatively low, it should be placed in the greenhouse for several days before use. At the same time, the temperature of the insulating glass curing area should not be lower than 10℃. b: Requirements for the surface of the substrate: all the adhered parts of the substrate should be cleaned to remove dust, oil or other dirt; when using offline low-emissivity coated glass to make insulating glass, the side sealing area must be carried out first In addition to membrane treatment. Experience sharing: The curing of hollow adhesive is a chemical reaction process, and temperature has a greater impact on its curing process. The appropriate use environment and maintenance environment are important environmental factors to ensure the best curing and bonding performance of the hollow adhesive. Dirt and dust will affect the final bonding performance, therefore, the surface of the substrate to be adhered must be cleaned. The film layer of the low-emissivity coated glass has poor compatibility with the structural adhesive. It is recommended that the coated glass be removed first during the processing to ensure a good adhesion between the hollow adhesive and the glass.

The secondary sealant for insulating glass has a great influence on the quality and service life of the insulating glass. The structural sealant for insulating glass is even directly related to the safety of the curtain wall. Therefore, we must choose the right product and the good product. The problems caused by improper selection of the second sealant can be divided into the following two categories: one is the loss of the function of insulating glass, that is, the loss of the original function of the insulating glass; the other is related to the safety of the application of insulating glass— -That is, the safety hazard caused by the falling of the outer sheet of insulating glass.
