Many people still don't know what Dow Corning's silicone is for?

Silicone based Dow Corning sealants have a longer service life and a wider range of applications than most organic polymer sealants. They are durable single component RTV sealants, and industrial silicone sealants cure into tough rubber like solids at room temperature with excellent performance characteristics. If the application requires industrial silicone sealant to withstand high temperatures or solvents, bond glass or metal, flow into cracks or gaps, or resist mold, I believe liquid silicone rubber can help meet your industrial needs.

Dow Corning's silicone is mainly used for assembly, bonding, sealing, gaskets, and other applications that require immediate bonding and high initial strength. It has unique characteristics: 100% silicone; Instant bonding; After curing, it becomes a long-lasting silicone sealant.

How long does it take for Dow Corning silicone sealant to cure? Allow curing: The sealant will cure within 5-10 minutes, and complete curing takes 24 hours, depending on environmental conditions.

Dow Corning 107 silicone rubber belongs to organic silicon products and is a colorless, transparent, flowing liquid. Its performance characteristics include:

1. Excellent weather resistance: able to withstand extreme temperatures and maintain elasticity even after continuous use from -62 ℃ to 232 ℃. Some products can be used intermittently at temperatures up to 280 ℃ and are not affected by sunlight, rain, wind, snow, ozone, etc.

2. Good electrical insulation: For example, Dow Corning 107 silicone rubber can be used in fields such as radio, electronic instruments, semiconductors, and other electronic components. It can be used as an insulation, moisture-proof, shock resistant, and heat-resistant sealing material.

3. Excellent sealing performance: such as Dow Corning 7091 silicone rubber, which has functions such as fixation, bonding, sealing, shock resistance, waterproofing, anti leakage, insulation, etc.

4. Good physical and mechanical properties: Some Dow Corning silicone rubber products have high tensile strength, ductility, and good wear resistance.

The application areas of silicone rubber are as follows:

1. In the industrial field, it is used for sealing and bonding equipment, as well as protective coatings for manufacturing equipment.

2. In the field of electronics and electrical engineering, it is suitable for packaging and encapsulation of electronic components, protection of circuit boards, and installation sealing of electrical components.

3. In the field of architecture, it can be used as a sealant for building doors and windows, for sealing glass, aluminum alloys, etc., such as Dow Corning NP neutral silicone sealant, SJ168 silicone weather resistant sealant, etc., which can be used for general building sealing and assembly applications.

4. In the automotive field, it is used for adhesive bonding of car decorations, assembly of car headlights and auxiliary lights, sealing of car body components, etc.

5. Medical field: Some medical grade silicone rubber materials, such as Dow Corning C6-265, C6-250, C6-235, etc., can be used for the manufacturing of medical devices.

How to choose the appropriate Dow Corning silicone rubber depends on its performance characteristics:

1. Physical properties: including hardness, tensile strength, elongation, tear strength, etc. If you need soft and elastic materials, you can choose models with lower hardness; For applications that require significant external forces, products with higher tensile strength and tear strength should be selected.

2. Chemical properties: Consider the chemical corrosion resistance, water resistance, oil resistance, etc. of silicone rubber. If there is a risk of chemical erosion in the usage environment, such as exposure to oils, solvents, etc. in industrial production, it is necessary to choose Dow Corning silicone rubber with good chemical resistance.

3. Electrical performance: If used in the field of electrical and electronic engineering, special attention should be paid to its electrical insulation performance, such as volume resistivity, dielectric strength, and other indicators. Like Dow Corning 107 silicone rubber, it has good electrical insulation and is suitable for insulation, moisture-proof, and sealing of electronic components.

4. Weather resistance: For outdoor use or applications exposed to different environmental conditions for a long time, the weather resistance of silicone rubber is crucial, including UV resistance, ozone resistance, high and low temperature resistance, and other properties. Many of Dow Corning's silicone rubber products have excellent weather resistance and can maintain stable performance within a temperature range of -55 ℃ to+180 ℃. The price of Dow Corning silicone rubber varies depending on different models and specifications.

When making a purchase, do not rely solely on price as the sole criterion. Consider the performance, quality, and actual needs of the product comprehensively, and choose products with higher cost-effectiveness. Sometimes, products with higher prices may better meet strict application requirements in terms of performance and quality, and in the long run, they may be more cost-effective.

In summary, Zhenkun Chemical has been operating silicone rubber for many years and has stable suppliers. In summary, the advantages of liquid silicone rubber include excellent processing performance, reduced cycle time, rapid thermal curing rate, reduced production costs, weather resistance, chemical stability, good adhesive strength, electrical performance, and low flammability.
