High temperature resistant adhesive used in circuit board soldering（THO4059）
Outline It is double-component epoxy adhesive. It is easy and convenient to use for it cures fast at room temperature and bonds well,
Applications It is applicable to the bonding of metals, the ceramics, the composite materials (PCB) materials working under the hot conditions. It also applies to the bonding, sealing repairing or soldering of electrical heating parts and components.
Features The A component is the tinted thick liquid, non-solid particle. The B component is in tinted paste shape.
Fast curing speed. At 100°C, within 0.45-1 hour, its surface cures, it reaches its maximum bonding strength when cooling down.
Being durable and resistant to ultraviolet light, once the bond has formed.
Being heat-resistant, it adapts to a wide range of temperature and bonds well under high temperature.
Mix the two components in a certain proportion, apply it to the surface of the substrates acquiring no strict treatment, which makes it so convenient to use.
You'll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes.
Non-toxic after solidification, though it is a little smelly.
Being stable, its shelf life is half a year.
The main technical parameters are as follows:
Heat resistance scope：-40°C—+380°C
Cementation intensity: room temperature: Tensile strength≥25MPa; Shearing strength≥20 MPa
At 150°C : Tensile strength 3－5 MPa
Instruction 1. To get the best results, the two surfaces being bonded should be free of oils, dirt, moisture and other contaminants and should be slightly roughed or sanded to remove gloss.
- Spread the mixture on the substrates, put them together and apply some strength on them, finally, heat it for 1 hour at 100℃.
Notes 1. Use another can or container to blend A with B. The tools used to get A and B should be different. - A and B should be mixed well.
- It is necessary to keep it well ventilated and away from fire.
- If it has contact with skin, you should wash thoroughly with soap and water.
- It can be stored at well-ventilated places with low temperature, and keep them away from fire.
- Cover the lip after using it.
