Silicone structural adhesive is a one-component polyurethane sealant, which is sealed with stone, glass, aluminum-plastic plate, ceramics, cement pipe, flange, oven, high-temperature mechanical seal, automobile, motorcycle and other high-temperature cylinder instead of the traditional gasket. The product is resistant to oil, sewage, antifreeze and automatic shift oil, with high temperature resistance of 350 ℃; it has excellent adhesive compatibility, high adhesive strength and good thixotropy , no solvent, excellent weather resistance, water resistance, oil resistance, low temperature resistance, aging resistance, no corrosion, no pollution, high strength, salt fog resistance, convenient construction, can be coated with a variety of coatings on the surface, overcoming the shortcomings of water resistance of acrylic sealant and oil resistance of polysiloxane, and can also be used for waterproof sealing of joints between various ceilings and walls, decoration, caulking, waterproof sealing of bathroom facilities and air conditioning of cold storage , automobile waterproof, dyke nuclear power station, airport runway and other special areas of sealing and bonding.

Silicone sealant is prepared by adding various fillers and auxiliary materials according to performance requirements. The silicone sealant is applied on the contact surface, and the glue liquid can fill the uneven contact surface. After curing, the silicone sealant will form a continuous viscoelastic adhesive layer which can bear a certain pressure and has a sealing effect.

Silicone structural sealant has more advantages than solid gasket. Such as good pressure tightness, simple and convenient coating, wide range of use temperature, low production cost, beautiful appearance, free forming, reducing the weight of components and so on. If silicone sealant and solid gasket can be used at the same time, the sealing performance will be better.

In the process of production and use of mechanical devices, the first sealing material used is solid gasket, but the effect is general, and the sealing effect is not very good. The appearance of silicone sealant, instead of solid gasket, provides the sealing effect for the device. So, which is better, silicone sealant or solid gasket?

Leakage refers to the leakage of working medium (such as lubricating oil) inside the mechanical equipment to the outside of the equipment, or the mineral particles, dust, moisture and other impurities in the external environment of the mechanical equipment invade the inside of the equipment. Silicone sealant is committed to solving the problem of oil leakage of the mechanical equipment, and silicone sealant has super oil resistance, even if it is in the corrosion state of oil immersion for a long time, it can still protect Stable.

Sealing is a measure to prevent leakage of mechanical equipment. Silicone sealant is a kind of adhesive used to prevent leakage of mechanical equipment. It is widely used in static sealing of mechanical equipment. It is a traditional static sealing method to add a solid gasket (piece) between two sealing surfaces.
