Characteristics and applications of silane-modified polymers
Excellent bonding performance: Silane-modified polymers can form strong chemical bonds with a variety of substrates, such as metals, plastics, glass, ceramics, etc., and provide reliable bonding effects. Whether in the connection of building structures, the assembly of automotive parts, or the packaging of electronic equipment, it can ensure the close bonding between components and effectively improve the overall performance and stability of the product.
Good weather resistance: It has excellent resistance to UV rays, high and low temperature, moisture and chemical corrosion. Under long-term exposure to outdoor environments or harsh industrial conditions, its physical and chemical properties change little, and it can maintain good sealing and bonding effects and extend the service life of the product. For example, when used in sealants for building exterior walls, it can effectively resist erosion by natural factors such as wind, rain, and sunlight.
Excellent environmental performance: The polymer is usually a single-component, solvent-free or low-solvent product, with less volatiles during use, less impact on the environment and human health, and meets environmental protection requirements. This makes it widely used in fields with high environmental protection requirements such as interior decoration, food packaging, and medical devices.
Good construction performance: moderate viscosity and thixotropy, easy for construction operation. It can be applied by brushing, spraying, extrusion and other methods. It can quickly solidify to form a glue layer with certain elasticity and strength under different working environments and construction conditions, improving construction efficiency.
Construction industry: used for building sealants, such as door and window sealing, curtain wall sealing, expansion joint sealing, etc., which can effectively prevent rainwater and air infiltration, improve the waterproof and thermal insulation performance of buildings; it can also be used as structural adhesives for bonding building components, such as stone, concrete, metal, etc., to enhance the stability of the structure.
Automobile industry: can be used for bonding of automobile windshields, body sealing, fixing of engine components, etc. It can withstand vibration, impact and temperature changes during the driving process of the car to ensure the safety and comfort of the car.
Electronic appliances: in the production of electronic equipment, it is used for packaging of electronic components, bonding of circuit boards, fixing of display screens, etc. It can protect electronic components from the influence of the external environment and improve the reliability and stability of electronic equipment.
Other fields: It is also widely used in aerospace, rail transportation, new energy and other fields. For example, it is used for bonding and sealing of aircraft structural parts in aerospace; in the field of new energy, it is used for encapsulation of solar panels and assembly of lithium batteries.
