thomas structural adhesive bonding magnets

Product name

High temperature resistant magnet steel adhesives（THO4058+）

Outline

It is double-component epoxy adhesive. It is easy and convenient to use for it solidifies fast at normal temperature and bonds well. The surface of the bonding is bright and smooth.

Applications

This product is widely applied to the bonding of such materials as motor magnetic ring (magnetic coil), magnetic metal, ceramics and composite materials in especially the high-speed electric machines. It also applies to the bonding, sealing, filling, repairing such materials as magnetic steel and magnet. 

Features

The A component is dope with various colors, The B component is transparent liquid.

Fast curing speed. At 25 °C, within 1-3 hour, the surface cures, and 2 days later, it reaches its maximum bonding strength.

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 directly, which makes it so convenient to use.

You.ll see long term durability and resistance to moisture, chemicals, oils, and temperature extremes.

Non-toxic after solidification, though it is a little smelly.

Shelf life is one and half a year.

The main technical parameters are as follows:

Temp. resistance scope：-52 °C－+225 °C

at room temperature: Tensile strength≥35MPa; Shearing strength≥28MPa peeling strength: 29KN/M

at 150°C  tensile strength 3-5 Mpa    volume resistance: (25°C) 1×1015Ω.cm      

surface resistance 2.5×1015Ω.cm   

voltage resistance 20-25kV/mm   hardness shore D 85   water absorbing capacity  24h＜0.1%   Tg:200°C

Instruction

1. Clean the surface of the material, make sure they have no dust or oil on them, wait until they are dry.

2. Mix A and B in a proportion of 3:1-1.2 to get perfect bonding result at fastest speed at 25 °C

3. Spread the mixture on the substrates, put them together and apply some strength on them, finally, let them dry for 2-4 hours.

Notes

1. Use another can or container to blend A with B. The tools used to get A and B should be different.

2. A and B should be mixed well.

3. It is necessary to keep it well ventilated and away from fire.

4. If it has contact with skin, you should wash thoroughly with soap and water.

5. It can be stored at well-ventilated places with low temperature, and keep them away from fire.

6. Cover the lip after using it.
