With the continuous progress and development of the adhesive/glue industry, the use of adhesives in all walks of life is increasing, and its application in the field of electronic information is quite extensive. Among them, adhesives are used in the bonding, sealing, potting, coating, structural bonding, co-lamination and SMT patch of electronic components, and the main glues are silicone glue, instant adhesive, UV glue epoxy glue, etc.
Among them, room temperature vulcanized silicone rubber or silicone gel is used for the potting of electronic and electrical components, which can play a role in moisture-proof, dust-proof, anti-corrosion, shockproof, and improve the use of performance and stable parameters, and it is liquid before vulcanization, easy to perfusion, easy to use. When applying silicone gel for potting, no low molecular weight is released, no stress shrinkage, can be deeply vulcanized, without any corrosion, vulcanized into a transparent elastomer, the components encapsulated in the rubber layer are clearly visible, and the parameters of the components can be measured one by one with a needle, which is convenient for detection and repair.
Room temperature vulcanized foam silicone rubber is used for the memory core board in the electronic computer, and it fully meets the requirements after many tests such as vibration, impact, cold and hot alternating. The flame-resistant potting glue prepared on the basis of molding room-temperature vulcanized silicone rubber is very effective for the molding of high-pressure caps and high-voltage cable wrappings for televisions.
For applications where hermetic encapsulation is not required or impregnation and potting protection is inconvenient, one-component room-temperature vulcanized silicone rubber can be used as a surface coating protection material. Generally, the surface protection coating of electronic components is coated with room-temperature vulcanized silicone rubber, and the internal coating is carried out with a molded silicone gel. In recent years, glass resin coated electronic appliances and instrument components have been widely used.
