Industrial customers pay more attention to the quality and stability of their products.

Although the price of silicone products is higher than that of epoxy resin, the market scale can still maintain stable growth.

The building curtain wall sealant mainly includes silicone weatherproof sealant and silicone structural sealant.

Organosilicon products are mainly composed of silicone and modified silane, with unique environmental quality.

Polysulfide adhesive is applicable to window or framed glass curtain wall, and silicone adhesive is mainly applicable to concealed framed glass curtain wall.

Its ultraviolet resistance and strength are higher than polysulfide adhesive.

The overall structure needs to be fixed by the second layer of sealant to bond the glass plate with the spacer strip.

It is estimated that the market scale of organic silica gel in China’s construction field (including traditional buildings+precast buildings) will reach 903000 tons in 2025.

In the future, we believe that the demand of organic silicone sealant for building curtain wall, insulating glass, door and window plastic sealing and decoration will continue to grow.

The demand for building glue can be divided into traditional buildings, precast buildings and other three fields, and other fields mainly include bridges, dams and other infrastructure.

The first layer of butyl adhesive is used for sealing.

It is estimated that the demand of organic silicone sealant for building curtain wall will reach 300000 tons by 2025.

The butyl adhesive itself has low adhesive strength and low elasticity.

Due to the surface characteristics of concrete components and plate displacement in precast buildings, higher requirements are put forward for the adhesive performance, elasticity, weather resistance and coating ability.

To sum up, we predict that the market scale of organic silica gel in China’s construction sector (including traditional buildings+precast buildings) will reach 903000 tons in 2025, with a CAGR of 14.33% in 2020-2025.

In the field of precast construction, the demand for rubber is expected to reach 943000 tons in 2025.

According to the “Fourteenth Five-Year Plan” for the Development of the Construction Industry and the “Carbon Peak Implementation Plan for Urban and Rural Construction”, the proportion of precast buildings in new buildings will reach 30% in 2025, and 40% in new urban buildings in 2030.

The demand for rubber for insulating glass will reach 195000 tons.

Adhesives in the traditional building field mainly play a sealing role in building curtain walls, insulating glass, door and window plastic sealing and decoration: curtain wall engineering, the design and treatment of joints in the design of building curtain walls mainly include the connection of transoms and metal mullions, the connection between buildings and curtain wall structures, the connection between metal frames and glass, and the connection of various connectors and embedded parts.

Silicone sealant is mainly used for sealing the joints of aluminum alloy doors and windows, plastic steel doors and windows, copper doors and windows, wood doors and windows, steel doors and windows, etc.

Large customers in the construction industry tend to use well-known products to highlight the quality and grade of their own buildings.

Building adhesives can be divided into structural adhesives (building structural adhesives, curtain wall structural adhesives, etc.) and non-structural adhesives (adhesive adhesives, sealants, etc.) according to their uses, including organic silicone adhesives, epoxy resin adhesives, polyurethane adhesives, acrylate adhesives, etc.

It is estimated that the total demand scale of organic silica gel will reach 652000 tons in 2025.

Silicone structural sealant has good adhesiveness and ductility, and is usually used for sealing aluminum alloy joints; Silicone weatherproof sealant has extremely strong ultraviolet resistance, which can be used between decorative panels and curtain wall panels, and also between metal frames and structural surfaces.

Although the traditional silicone sealant for building has good weather resistance and low modulus (high elasticity and displacement capacity), it is poor in the adhesion and finishing of concrete components.

The sealant for precast building mainly consists of polyurethane sealant, silane modified polyether sealant (MS sealant) and silicone sealant, MS sealant has good comprehensive performance.

The insulating glass is divided into two seals.

The precast construction industry has entered a period of rapid development.

The sealing and decoration of doors and windows mainly include silicone rubber and silicone rubber sealing strip.

We believe that the incremental market of precast building mainly comes from silicone sealant, which is mainly due to three reasons: 1.

The second layer of sealant mainly includes polysulfide adhesive and silicone adhesive.

In addition, sealant can also be used for indoor and outdoor decoration, including the sealing of glass, ceramic tiles, decorative materials, walls, floors, ceilings, anchor line joints, etc., as well as the sealing of furniture assembly, furniture hardware, wood, glass and other materials.

The demand for decoration glue will reach 107000 tons.

In the construction field with increasingly stringent environmental requirements, silicone products will continue to replace acrylic adhesives, epoxy resin adhesives and traditional rubber products.
