Application of Silicone Sealant in Electronics and Appliances

Silicone sealant is a commonly used multifunctional polymer adhesive that can bond various substrates such as metals, organic plastics, glass, ceramics, etc. It has excellent properties and is widely used in the field of electronics and electrical appliances. Not only can it meet the design needs of electronic and electrical products, but it can also improve production efficiency and reduce costs. It is one of the indispensable important auxiliary materials in this field. From household appliances such as washing machines, water heaters, and rice cookers, to semiconductor devices such as integrated circuits, circuit boards, and chip packaging, silicone sealant can be found everywhere.

Specific advantages of silicone sealant

Wide operating temperature range, and the working performance changes little after forming an elastic body, with some elasticity and good tensile resistance. It can compensate for the deformation caused by thermal expansion and contraction of various substrates, reduce wear and tear of electronic components, extend their service life, and facilitate maintenance when faults occur.

Silicone adhesive sealants offered by professional silicone sealant manufacturers and suppliers has excellent electrical insulation properties. Test data demonstrates that these sealants exhibit good electrical insulation performance within a temperature range of -60°C to 200°C. Furthermore, variations in frequency and temperature have minimal impact on the dielectric constant and dielectric loss factor of the sealants. This effectively enhances the safety and stability of electronic and electrical operations.

Simple and flexible construction operation, with low-cost, efficient, and fast gluing equipment. For example, single-component silicone sealant can be accurately applied during use, suitable for adhesive bonding of small parts inside electronic and electrical components.

Excellent aging resistance can prolong the service life of electronic and electrical components and make them less prone to faults during use.

High flexibility in formula adjustment. By adding functional fillers to silicone based sealant material, special function silicone sealant can be achieved. For example, silicone sealant with thermal conductivity is used in electronic and electrical appliances to ensure that the internal heat dissipation components can achieve quick heat dissipation through thermal conductive silicone sealant, protecting electronic components and maintaining stable operation of electronic products. Other functional silicone adhesive sealants include conductive silicone sealant, flame-retardant silicone sealant, and high-temperature-resistant silicone sealant.

Excellent light resistance makes it have a special application in electronic and electrical appliances, such as photovoltaic silicone sealant used in solar cell modules.

Specific applications of silicone sealant

Silicone sealant can be used for fixing components, filling heat sinks, bonding glass panels and partitions, fixing storage boxes and frames in household appliances such as refrigerators, air conditioners, washing machines, etc.; for bonding kitchen appliances, such as range hood panels, microwave oven coil/microcrystalline plate bonding, microwave oven cavity doors, oven doors, door handles bonding; for bonding small home appliances, such as hot water kettle, health pot bottom and body bonding, electric iron heating plate, shell bonding, etc. You can also find silicone for window sealing as well as a weather-resistant neutral silicone adhesive in Zhongtian! 

It can also be used for sealing and bonding control panels of household appliances during cleaning, sealing and bonding washing machine and dishwasher cover/box, bonding vacuum cleaner water tank, and fixing soft hoses and metal sheets. It can be used in photovoltaic cell components as well. In the service process of photovoltaic buildings, they have to withstand harsh weather conditions such as sun and rain. Silicone sealant can be applied in adverse weather conditions, such as gaps between photovoltaic cell module frames, power junction boxes, photovoltaic glass, etc., to protect solar cell photovoltaic components and extend their service life.
