A New Breakthrough for Vinyl Silicone Fluids

Silicone sealant is a major application field of silicone oil. Silicone sealants are found in various electronic appliances, vehicles, and buildings in life. Just as mountains cannot be separated from sand, and buildings cannot be separated from pillars, vinyl silicone oil and silicone sealant are inseparable.

1. The main application of silicone sealant

1. Traffic equipment manufacturing

Mainly used in field forming gaskets and bonding and sealing of automobile engines, windshields, door and window frames, reflectors, exhaust pipes, lights, instruments, containers, car boxes and other equipment susceptible to water spray. Silicone sealant has excellent water resistance and lubricating oil resistance, and can be used in water-based systems such as pumps and water tanks, and systems with lubricating oil as a medium such as engines, gear boxes, cam boxes, transformers, and hydraulic systems.

2. Power Materials

Silicone sealant has low thermal expansion coefficient and excellent insulation and heat preservation performance; excellent waterproof performance, the cured colloid can effectively prevent the entry of condensed water; corrosion resistance can ensure long-term work in acid and salt environments; outstanding aging resistance Its service life can be as long as 50 years, so silicone sealants are widely used in insulation, moisture-proof sealing, environmental protection and anti-corrosion, encapsulation and bonding of cable accessories.

3. Electronic components and radio industry

Room temperature curing silicone sealant is widely used in the field of encapsulation, sealing, bonding, dipping and coating, etc., to seal integrated circuits, micro-film components, thick-film components, electronic assemblies or the whole machine. The inner components are clearly visible and the component parameters can be accurately measured. With the continuous development of the industry, in order to ensure the stability and durability of the performance of power supply equipment in the application of various industries, and to eliminate the impact of environmental factors (moisture, salt spray, dust, vibration, heat, etc.) on power supply equipment As a result, the reliability of the equipment is reduced, and the application of silicone sealants in the power supply industry is becoming more and more extensive.

2. When silicone sealant encounters vinyl silicone oil

Silicone sealant can improve the stability of electronic components and the whole machine, so that it can avoid being polluted and eroded by water vapor, impurities and various chemical substances in the atmosphere, so that the whole machine can stably perform normal electrical functions. Therefore, in order to ensure the stable performance of the sealant, vinyl silicone oil is usually used as the base material in production, and cross-linking agent, powder, etc. are added through a certain formula ratio, and it is produced into one or two components according to specific use requirements. In the production of silicone sealant, vinyl silicone oil requires low water content and low ion content. In order to ensure the fluidity and mechanical properties of the sealant, vinyl-terminated silicone oil with low viscosity is often used, and when the side-chain vinyl silicone oil is selected, the cross-linking points are denser and the mechanical properties are better.
