Silane coupling agent can improve the strength and structural properties of building materials
Author:LongKom  Time:2018-4-12

The quality of our life and the quality of our community experience largely depend on whether we have safe and healthy living, work and entertainment places. We need safe, comfortable, fashionable and durable housing, schools, entertainment, hospitals and religious places. Silicone polymers with high performance and high technology have been used in new architecture and innovative design in many ways, making thousands of building materials have better performance and longer life. Today, more design choices mean that we can save more resources for future generations.

Silicone coupling agent improves strength: Silicone can improve the strength and structural properties of building materials. It can even bond various materials together, such as concrete, glass, granite, marble, aluminium, steel and plastics. Silicone coupling agent for building protection: Silicone coupling agent can protect the integrity of building structure and make it withstand the test of time. Silicone sealants (commonly known as organosilicon gel), adhesives, structural assembly materials and coatings have excellent resistance to heat, rheumatism and chemical erosion, even in extreme weather conditions can also slow down the external erosion of building and building materials.


Silicone coupling agent improves performance: the material requirements of modern buildings are incredible. Silicone meets these requirements by enhancing the strength of materials and giving them high flexibility in design. For example, silicone sealants and assembly materials can make hollow glass panels have better thermal, ultraviolet and seismic properties, making them strong enough to be used in large building structures. Without sacrificing structural integrity or isolation, buildings can get more natural lighting. 


Silicone Coupling Agent for Heritage Protection: Silicone can be used to repair historic buildings without causing damage to their appearance. The protective layer formed by silicone sealants and adhesives can reinforce natural materials and enhance their water resistance and air permeability. Therefore, silicone can help to restore the strength and permeability of peeled walls, damaged structures and aging joints without destroying the integrity of the original materials.

Typical applications of silicone coupling agent: The following applications fully illustrate that silicone can meet the performance requirements and aesthetic standards of constructors, architects, designers, engineers and other architectural professionals for a long time.


Exposure of building sealants and adhesives to the natural environment remains a major headache for architects and builders of industrial and commercial buildings. Silicone used in structural assembly system can protect the appearance and quality of buildings for a long time. The final product is almost free from sunlight, rain, hail, snow, heat, cold, ultraviolet radiation and air pollution, whether it is made of silicone or coated with silicone. Because the design characteristics such as elasticity, tensile strength, hardness and adhesion will not change greatly with time, the service life of buildings is longer and the maintenance requirements are less. Structural sealants used in protective or impact-proof windows can provide more protection for households or passers-by in harsh weather, fire, earthquake, explosion or illegal intrusion. Silicone assembly system can be used for industrial laminated windows of new buildings and film of existing windows. Effectiveness - Reduce the possibility of broken glass debris falling off the window frame, and improve the safety. Structural sealants also have excellent isolation. Manufacturers usually use silicone to make hollow glass panels and components for building exterior walls. Glass can effectively withstand the cold winter, hot summer, ultraviolet radiation and humidity and other external environment, and has the characteristics of low water absorption and high adhesion of organosilicon.


Silicone coupling agents are used in engineering sealants and adhesives: Silicone is very suitable for bonding materials and can be used for expansion, construction, joining and moving joints (such as bridges). The physical elasticity of the elastic joint can fix the position of the object, but also buffer the natural displacement and movement of materials caused by the changes of temperature, humidity, wind and other environmental factors. The use of silicone in the joints of newly paved and repaired concrete pavement can increase the service life of expressways, Airport runways, bridges, docks, garages and residential streets. Silicone can withstand drastic expansion and contraction changes. At the same time, silicone will not react with fuel oil, hydraulic oil and cleaning solvents commonly found on busy industrial roads.


Silicone coupling agent used in building coatings: After adding silicone, the coatings can withstand many years of outdoor climatic conditions without erosion, so they can be used for decoration and commercial purposes. Silicone can be easily added to various coatings, including powder coatings, liquid coatings, primers and varnishes, making the above coatings "readily available" water-borne, powder and emulsion materials. In stone, pouring and precast concrete, grooved stone, brick, mortar and other materials, the role of paint is more prominent. Silicone latex and gypsum are the most modern and successful external coatings. Silicone resin adhesives can not only plug holes and make them water-resistant, but also strengthen their structure.
