Intuitively understand MS glue
What is MS glue
MS glue is the abbreviation of silane modified polyether glue, which is mainly polymerized with MS One-component or two-component elastic sealants are based on polymers, combined with fillers, plasticizers and other functional additives. They are developed after silicone glue (SR) and polyurethane glue (PU). A new generation of construction sealants. Mainly used in bonding, caulking, joints, sealing, waterproofing, reinforcement and other fields of construction engineering and decoration. As people’s understanding of the advantages of MS glue continues to deepen, its application in the refrigerated trucks, containers, and elevator industries is also expanding.
What kind of development has MS glue experienced
In 1979, Kaneka of Japan successfully developed silicone modified Polyether sealant (also called silyl-terminated polyether sealant) base polymer.
In 1980, Kaneka Company of Japan first prepared silane-terminated polyether-based It is an elastic sealant made of raw materials and began to be promoted and applied in large buildings and high-end buildings in 1981.
After 1982, Japan, the United States and European countries competed for terminal silyl polyethers Research on basic polymers and their elastic sealants and elastic adhesives has promoted the rapid development of MS adhesives.
In recent years, MS glue has emerged as a new force, with the number of manufacturing companies increasing and related technologies advancing rapidly. It occupies an increasing share of the world’s construction sealant market.
MS glue composition
The main raw materials of MS glue include: terminal alkyl polyether (MS pre-With the yearning for life and the pursuit of environmentally friendly decoration, MS glue has broad development space.

Application of MS glue in construction
With the rise of high-rise buildings and the specialization of construction methods The development of plastics has put forward higher requirements for the performance of waterproof materials, adhesives, sealants and other materials, especially in terms of environmental protection, energy saving, aesthetics, etc. Therefore, MS glue with excellent performance has received widespread attention as soon as it appeared. And its share in the world’s sealant market has steadily increased. According to relevant survey reports, in the European sealant material market, MS glue’s market share is about 10%. With the growth of China’s economy, especially construction methods With the development and upgrading of residential buildings, concepts such as residential industrialization and local material selection are gradually becoming familiar to people. The development of MS glue suitable for Chinese architectural characteristics is highly anticipated by the market. See Figure 9 and Figure 10 for details.

The current situation of MS glue in China
The MS glue market is booming in 2017, according to statistics , as many as 17 seminars on MS glue were held between March and October 2018. Participants were enthusiastic and the organizations holding the meetings made a lot of money. However, recently, a large number of manufacturers that were tempted by high profits and transformed into the production of MS glue began to stall? Mainly The reasons are as follows:
1. Prices of silicone oil and 107 glue in the first half of this year The continuous surge has attracted many silicone glue manufacturers to transform into MS glue production. However, due to the lack of mature MS glue production technology, and the uneven quality of domestic silane-modified polyether resin (the basic raw material of MS glue), it is difficult for them to Maintain the stability of product quality.
2. Real estate construction continues to fall and market demand decreases . At the end of October 2018, silicone oil and 107 glue dropped sharply to about 21 yuan/Kg, causing the production cost of MS glue to lose its advantage.
3. Overcapacity and following the trend are serious. According to statistics , as of 2018, there are more than 500 MS glue production devices in China that have followed suit, leading to the reappearance of overcapacity and the emergence of low-price competition and price wars.
