High temperature resistant adhesive（THO4098）
Outline It is heterocyclic adhesive which cures fast when heated. it is temperature resistant and easy to operate. No bubbles appear after curing thus making the surface smooth and bright.
Applications It applies to the coating and encapsulating of device surface, electronic components and chips to protect them against moisture, chemicals, excessive heat, vibration, mechanical impact and thermal shocks. It also applies to the coating of sensors which works in tough conditions such as extreme weathers, temperature shocks and so forth.
Features It is one-component white viscous fluid.
It cures within 20 minutes when heated with the temperature 120-140°C.
It is resistant to shock, ultraviolet light and extreme weather once it cures because it is durable and with good ductility and low contraction coefficient.
Being heat-resistant, it adapts to a wide range of temperature and bonds well under high temperature.
Being moderate in viscosity, the surface appears smooth and bright after curing.
Apply the adhesive to the surface of the substrates directly or fill it into the gap, then heat it...
You'll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes.
Flame retardance: comply with UL94-V0.
Non-toxic after it cures and it is upto the RoHS standard.
Being stable, its shelf life is one year when stored at the temperature of 5°C.
The main technical parameters are as follows:
Heat resistance scope：- 52 °C—+ 450 °C
Non-yellowing test: it stays white when heated at the temperature of 280°C for 6 hours viscocity: 10000-15000mpa.s
voltage withstand 28-35.5kV/mm hardness: shore D85
Tensile strength≥25MPa; bending strength≥23 Mpa compressive strength≥75MPa shearing strength≥28.8Mpa shock strength≥17KJ/m*m
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 or smear the substrates with the special liquid.
- Spray the adhesive on the substrates, put them together and apply some strength on them, heat it with 120°C, wait for one minute and let it dry
Notes 1. Better to keep the working place well ventilated.
2 .If it has contact with skin, you should wash with soap. - It can be stored at well-ventilated places with low temperature, and keep them away from fire. Cover the lip after using it.
