The quality of our lives and the quality of our community experience largely depend on whether we have safe and healthy places for living, working, and entertainment. We need homes, schools, entertainment, hospitals, and religious venues that are safe, comfortable, fashionable, and durable. High performance and high-tech organic silicon polymers are applied in various ways to new types of buildings and innovative designs, resulting in better performance and longer lifespan of thousands of building materials. Nowadays, more design choices mean that we can save more resources for future generations.

有机硅烷偶联剂可以提高建筑材料的强度及结构性能

Organic silicon coupling agent enhances strength: Organic silicon can improve the strength and structural properties of building materials. It can even bond various materials together, such as concrete, glass, granite, marble, aluminum, steel, and plastic. Organic silicon coupling agents protect buildings: Organic silicon coupling agents can protect the integrity of building structures and withstand the test of time. Organic silicone sealants (commonly known as organic silicone), adhesives, structural assembly materials, and coatings have excellent resistance to heat, moisture, and chemical corrosion, and can slow down external erosion of buildings and building materials even under extreme weather conditions.

 

Organic silicon coupling agent improves performance: The requirements for materials in modern construction are incredible. Organosilicon meets these requirements by enhancing the strength of materials and endowing designs with a high degree of flexibility. For example, silicone sealants and assembly materials can enhance the heat resistance, UV resistance, and seismic resistance of insulated glass panels, enabling them to achieve sufficient strength for use in large building structures. Buildings can obtain more natural lighting without sacrificing structural integrity or isolation. Therefore, it is not surprising that some of the most spectacular buildings in the world use organic silicon materials for good lighting.

 

Organosilicon coupling agents protect heritage: Organosilicon can be used to restore historical buildings without causing damage to their appearance. The protective layer formed by silicone sealant and adhesive can reinforce natural materials and enhance their water resistance and breathability. Therefore, organosilicon can help restore the strength and breathability of peeled walls, damaged structures, and aging joints without damaging the integrity of the original material.

 

Typical applications of organosilicon coupling agents: The following applications fully demonstrate that organosilicon can meet the performance requirements and aesthetic standards of construction personnel, architects, designers, engineers, and other types of building professionals in the long term.

 

Exposure of building sealants and adhesives to the natural environment remains the primary concern for architects and construction workers in industrial and commercial buildings. Organic silicon used in structural assembly systems can provide long-term protection for the appearance and quality of buildings. Whether using materials produced from organic silicon or materials coated with organic silicon surface, the final product is almost unaffected by sunlight, rain, hail, snow, heat, cold, ultraviolet radiation, and air pollution. Due to design characteristics such as elasticity, tensile strength, hardness, and adhesion that do not undergo significant changes over time, buildings have a longer service life and require less maintenance. In adverse weather conditions, fires, earthquakes, explosions, or illegal intrusion, structural sealants used in protective or impact resistant windows can provide more protection for residents or passing pedestrians. The silicone assembly system can be used for industrial laminated windows in new buildings as well as adhesive film for existing windows. The effect reduces the possibility of broken glass fragments falling off the window frame, improving safety. Structural sealants also have excellent isolation properties. Manufacturers typically use silicone to make insulated glass panels and components for building exterior walls. Glass can effectively withstand external environments such as cold winter, hot summer, ultraviolet radiation, and humidity, and has the low water absorption and high adhesion characteristics of organic silicon.

 

Application of organic silicon coupling agent in engineering sealants and adhesives: Organic silicon is very suitable for material bonding and can be used for expansion, construction, connection, and moving joints (such as bridges). The physical elasticity of elastic joints can fix the position of objects while also buffering the natural displacement and motion between materials caused by changes in temperature, humidity, wind, and other environmental factors. The use of organosilicon at the joints of newly laid and repaired concrete pavement can increase the service life of highways, airport runways, bridges, docks, garages, and residential streets. Organosilicon can withstand severe expansion and contraction changes. Meanwhile, organosilicon does not undergo chemical reactions with materials such as fuel, hydraulic oil, and cleaning solvents commonly found on busy industrial roads.

 

Application of Organic Silicon Coupling Agents in Architectural Coatings: Coatings with added organic silicon can withstand years of outdoor weather conditions without erosion, making them suitable for decoration and commercial purposes. Organosilicon can be easily added to various coatings, including powder coatings, liquid coatings, primers, and varnishes, making them "readily available" water-based, powder, and emulsion materials. In materials such as stone, poured and precast concrete, grooved stones, bricks, plaster, etc., the role of coatings is more prominent. Organic silicone resin latex and gypsum are the most modern and successful external coatings. Organic silicone resin adhesive can not only block pores and make them resistant to water, but also enhance their structural strength. Organic silicone primer can also strengthen the underlying material and enhance the adhesion performance of the surface coating.

 

The term 'industrial strength' for industrial coatings and maintenance refers to materials made from organic silicon. Industrial surface—— Bridges, drilling platforms, and railway cars must be able to withstand various destructive conditions excellently, while also being more durable than consumer coatings. The organic silicon in anti-corrosion coatings and gypsum can protect industrial surfaces and structures, making them longer and more aesthetically pleasing. Thanks to the rapid advancement of organic silicon technology, today's external coatings are not only more durable, but also have better ability to withstand sun exposure, salt corrosion, pollution, and aging. Organic silicon coatings have excellent adhesion, pigment dispersion, and resistance to chemicals, harsh weather conditions, and various pollutants. The new silicone enhanced coating can maintain the elasticity of external coatings, making them resistant to freezing/thawing without cracking, powdering, peeling or foaming. Effectively reduce the erosion of surface coatings by chemical substances such as oil, gasoline, salt spray, and acid rain. Stains and wear caused by pollution, vehicles, and other adverse factors will not affect the lifespan of industrial surfaces.

 

Application of organic silicon coupling agents in water-resistant additives: Water can cause the most serious damage to buildings. Moisture and dampness can erode the exterior, consume adhesives at joints, reduce the insulation of structures, and may transfer harmful substances such as bacteria to the interior of buildings, increasing health risks. Organic silicon stone water-resistant agent can provide the most effective waterproof protection. Waterproofing agents can be added to any type of coating, gypsum, and topcoat to enhance the waterproofing performance of building materials and optimize the coating's water resistance, waterproofing, and water vapor permeability. Unlike other coatings, silicone waterproofing agents do not seal holes, but instead form an extremely thin layer of protective film on the hole wall, reducing the entry of moisture without sacrificing the material's breathability or breathability. External moisture cannot penetrate the material, but accumulated moisture inside can still escape. Water resistant treatment is particularly effective in ordinary and reinforced concrete, aerated concrete, natural stone materials, limestone, brick laying, and gray sand bricks. Organic silicon can prevent glass from fogging due to moisture infiltration.

 

Many important cultural relics in the world are protected and restored using natural materials such as porous sandstone and porous limestone, making them particularly susceptible to climate influences. Organic silicone sealants and adhesives can penetrate into the stone material (directly to the undamaged core) and reinforce natural materials, thereby restoring their original strength. This process does not affect the physical properties of the stone or structure, such as breathability or permeability, as well as thermal and hydrophilic properties. In fact, organosilicon can enhance many of the aforementioned characteristics. In addition, the application of organosilicon is uniform, so it can avoid stains or stripes.
