Driven by the rapid development of prefabricated buildings, the construction sealant industry has huge development potential

Sealant refers to a sealing material that deforms according to the shape of the sealing surface, is not easy to flow, and has high adhesion. There are a wide variety of sealant products. According to different main components, they can be divided into polyurethane, polysulfide, rubber, acrylic, silicone polymer sealants, etc. Construction sealants refer to sealants used in the construction field. The main application scenarios include building curtain walls, door and window sealing, insulating glass processing, building decoration, etc.

Building sealants are used to seal various joints and holes in buildings and decorations to prevent gases, liquids, and solids from penetrating and preventing structural damage caused by displacement. Therefore, building sealants are required to have good temperature resistance. Bonding performance, displacement performance, paintability, thermal stability, anti-corrosion performance, weather resistance, creep resistance, etc. At present, the common types of building sealants mainly include silicone (silicone) sealant, polyurethane sealant, and polysulfide sealant. Among them, silicone sealant is the current mainstream product in the domestic construction sealant market.

In recent years, with the strong support of national policies and the continuous advancement of low-carbon and environmentally friendly construction goals, the domestic prefabricated construction industry has developed rapidly, and the construction area has continued to expand. According to data from the Ministry of Housing and Urban-Rural Development, the area of ​​newly constructed prefabricated buildings nationwide in 2021 will reach 740 million square meters, an increase of 18% from 2020, accounting for 24.5% of the newly built building area.

As a type of prefabricated spliced ​​building, construction sealant is an indispensable key material for prefabricated buildings. The performance of construction sealants has an important impact on the quality and quality of prefabricated buildings. According to the “China Construction Sealant Industry Application Market Demand and Development Opportunities Research Report 2023-2027” released by the Industrial Research Center, In 2021, my country’s construction sealant market will be close to 22 billion yuan. Among them, building curtain walls are the largest application scenario for building sealants, and their application proportion will be approximately 45.0% in 2021.

Driven by the continued growth in demand, many domestic companies have poured into the construction sealant market. Major companies include Silicon Bao Technology, Baiyun Chemical, Jitai Chemical, Huitian New Materials, Yongan Rubber Industry, Lingzhi New Materials, and Zhijiang Silicone Chemicals. wait. At present, there are a large number of construction sealant companies in my country, and the market structure presents a situation of fierce competition and price competition in the middle and low-end markets, prominent branding in the high-end market, and a relatively stable market structure.

Industry Analysts personnel said that as a key raw material in the construction field, construction sealants have seen significant investment in domestic infrastructure in recent years. Against the background of the continuous expansion of scale and the rapid development of the prefabricated construction industry, its market demand continues to increase and its scale continues to expand. As a country with major infrastructure construction, my country will continue to develop the construction sealant industry in the direction of green and environmental protection under the background of rising green and low-carbon development trends in the domestic construction industry in the future, and the industry has broad room for development.
