Electronic glue is a wide name, mainly used for bonding, sealing, potting and coating protection of electronic components.
The main representatives of electronic glue are silicone sealant and silicone potting compound.
Room temperature vulcanized silicone rubber or silicone gel is used for potting of electrical and electronic components, which can protect against moisture, dust, corrosion and shock, improve the performance and stability parameters, and it is liquid before vulcanization. Perfusion, easy to use. When silicone gel is used for potting, it does not emit low molecular weight, no stress shrinkage, deep vulcanization, no corrosion, and vulcanized into a transparent elastomer. The components encapsulated in the adhesive layer are clearly visible and can be used for needle punching. The component parameters are measured one by one to facilitate inspection and rework. The room temperature vulcanized foamed silicone rubber is used in the memory magnetic core board of the electronic computer, and the tests such as vibration, impact, cold and heat alternating are fully met. The flame-resistant potting compound prepared on the basis of the addition of room temperature vulcanized silicone rubber is very effective for molding of products such as TV high voltage caps and high voltage cable sheaths. One-component room temperature vulcanized silicone rubber can be used as the surface coating protective material for the case where it is not required to be hermetically sealed or inconvenient to perform the impregnation and potting protection. The surface protection coating of general electronic components is performed by using room temperature vulcanized silicone rubber and internally coated with an addition silicone gel. In recent years, glass resin coated electronic appliances and instrument components have been widely used.
Electronic glue classification
Folded silicone sealant
Silicone sealant is a one-component, non-flowing paste, dealcoholized room temperature vulcanized silicone rubber. The condensation reaction by the moisture in the air releases low molecules to cause cross-linking and solidification, and vulcanizes into a high-performance elastomer. Excellent resistance to cold and heat alternation, aging and electrical insulation. It has excellent insulation, moisture resistance, shock resistance, corona resistance, leakage resistance and chemical resistance. It can be used continuously at -60~~200°C and maintains its performance. It can seal and bond electronic components and not pollute the surrounding environment, and fully meet the requirements of the EU ROHS directive.
This product is suitable for various structural adhesive seals in industrial production, such as: structural bonding of steel plates in automobile compartments; insulation bonding and sealing of high voltage parts such as TV, power supply, CRT picture tube, DY deflection coil; PCB sensitive Fixation and bonding of components, capacitors, triodes, etc.; refrigerator, microwave oven, induction cooker, circuit board, electronic components, solar cell bonding and sealing; delicate electronic components for moisture-proof and waterproof packaging; automotive headlight gasket sealing; Adhesive sealing of wear-resistant ceramic sheets and window frame mounting glass; elastic bonding to most metal and non-metal materials, especially suitable for elastic bonding under special temperature requirements; electric power, electronics, electrical appliances, medical Machinery, sensors, mechanical equipment, refrigeration equipment, shipbuilding industry, automotive industry, chemical light industry, wire and cable insulation bonding reinforcement protection.
Folded silicone potting compound
Silicone potting compound is a one-component, low viscosity, dealcoholized room temperature curing silicone high temperature bonding potting compound. The condensation reaction by the moisture in the air releases low molecules to cause cross-linking and solidification, and vulcanizes into a high-performance elastomer. It has excellent resistance to cold and heat changes, resistance to stress changes, high temperature resistance, high flexibility and stability at high temperatures, UV resistance and aging resistance. It has excellent insulation, moisture resistance, shock resistance, corona resistance, leakage resistance and chemical resistance. It can seal and bond electronic components and not pollute the surrounding environment, and fully meet the requirements of the EU ROHS directive.
