There is an idiom to describe passionate feelings and inseparable feelings, called "like glue like paint", which originally means to stick together like glue and paint, and later refers to the love of husband and wife. The word "like glue like lacquer" originally originated from Sima Qian's "Historical Records: Biography of Lu Zhonglian and Zou Yang" in the Western Han Dynasty: "It feels in the heart, fits in the action, and is close to the glue paint. Brother Kun can't leave, so it will confuse everyone." At the beginning, it was used to describe the relationship between husband and wife. Although no idioms were formed, the terms "glue" and "lacquer" appeared in the Western Han Dynasty more than 2,000 years ago.
If you ask what "glue" is, you may not think about it, it must be rubber. In fact, although the utilization of rubber has a certain history, natural rubber is originally produced in the rubber tree (Hevea brasiliensis) in Central and South America, which has no direct relationship with China more than 2,000 years ago, so we will not discuss it in depth.

Use of Silicone Silicone in China
Although the development of household silicone began in the 1960s, it was primarily used in the defense industry. In the 1980s, it began to turn to civilian use. However, due to conditions, there are not a large number of products on the market. After entering the 1990s, the speed of development has been greatly accelerated.
In the early 1980s, my country began to use silicone structural adhesive products in the installation of the first glass curtain wall of the Great Wall Hotel in Beijing. In the 1990's a lot of silicone structural adhesives were used to glue and seal frames that were completely hidden. Semi-hidden frame curtain walls, the highest Shenzhen Diwang Building, Guangzhou CITIC Plaza and Shanghai Jinmao Tower were completed in the 1990s, all using hidden or semi-hidden frame glass curtain walls, and all silicone structural adhesives used are imported products.

What is a silicone sealant?
Silicone sealant is an important part of silicone polymer materials. It can be cured into elastic strips at room temperature without heat, light or other conditions. It is very convenient to use except for general purpose. In addition to excellent properties such as high low temperature resistance, weather resistance, and high electrical insulation, silicone materials also have good adhesion and displacement resistance to various substrates. They have developed into an important stamp of modern architectural decoration. In terms of materials, users can choose corresponding types of products according to different uses. Silicone sealant is a type of silicone product.

Silicone sealant is divided into two types
One-component and two-component.
One-component silicone glue, its curing is the change of physical properties when exposed to moisture in the air.
Two-component means that the silicone glue is divided into two groups, A and B. Either group alone cannot form a cure, but once the two groups of glue are mixed, they will be cured. One-component sealants are common on the market.
One-component silicone glass glue is an ointment-like material that cures to a tough, rubber-like solid upon exposure to moisture in the air. Silicone glass glue has strong adhesive force, high tensile strength, and at the same time has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptability to large changes in cold and heat. Coupled with its wider applicability, it can realize the bonding between most building materials, so its application value is very large.
