We know that electronic adhesives are only one kind of industrial adhesive application classification, industrial for the same material or different materials with adhesive connected together technology. Generally speaking, industrial glue has the characteristics of high strength, wide range of applicable temperature, high strength, wide range of viscosity selection, low price, easy production and so on. Because of the convenience and efficiency, it replaces a lot of trouble to fix the way.
Common classification of electronic adhesives 1, conductive adhesive
Conductive silver adhesive, because of its conductive, electromagnetic shielding and other functions, is widely used in electronic products, especially in mobile phones, wireless communications for high frequency signal anti-interference circuit almost will be used.
2, quick drying glue
Single component adhesive, also known as instant glue or quick-drying glue, viscosity objects can be cured instantly, generally from 10S to 60 seconds, can have different viscosity, good adhesion to metal, plastic, rubber, the main application is headphones, data cable, selfie stick, mobile phone buttons, mobile phone shell, etc.
3, epoxy rubber AB rubber
Can be a single or two component acrylic acid, epoxy resin, heating and room temperature curing two kinds of curing, with high shear strength, fast fixing, high temperature and humidity, impact resistance, weather resistance and other advantages. It has high bonding strength for most substrates, and can bond metal, plastic, rubber, glass, etc. The main application has the mobile phone tablet back shell, laptop shell, large area of shell adhesion and mutual adhesion.
4, hot melt structural adhesive
There are many kinds of hot melt adhesive, and PUR hot melt adhesive is one of the best, has a strong adhesive, also known as hot melt structural glue, is a kind of moisture curing adhesive, due to irreversible curing, so more resistant to high and low temperature, is widely used in electronic products, such as mobile phone plate screen, TP frame, metal and plastic shell parts bonding, most product screen.
5, polyurethane adhesive
Single component or two component adhesive, slightly surface treatment of thermoplastic and thermosetting plastics have good bonding properties, catalytic curing, thermal curing, evaporative solvent curing three curing methods, generally slow curing. With good flexibility and durability.
6, anaerobic glue
A one component adhesive/sealant that can be curable only under air free conditions. Used for thread locking, cylinder holding, pipe thread sealing, plane sealing, etc.
7, UV Shadowless glue
UV curable adhesive single component, no solvent, also called shadowless glue or UV curing glue, long operation time, in UV light 10 seconds can be cured, this advantage makes it is also widely used, the disadvantage is that at least one side to light. Application of solder joint reinforcement, line reinforcement, fixing, coating.
8, industrial silicone
Single component silicone adhesive/sealant, RTV silicone has the advantages of weather resistance, high temperature resistance, mainly used in electronic products need to seal, waterproof, heat conduction and other functions of the product, such as waterproof mobile phone, waterproof watch, circuit board without fixing.
