| Name | UV curing high temperature resistant adhesive（THO4094-4） |
| Outline | It is heterocyclic adhesive which cures fast with UV light. 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, infiltrating and encapsulating of device surface, electronic components and chips in electric engine, capacitor, thermocouples, transformers, rectifiers, electronic modules LSI and other products to protect them against moisture, chemicals, excessive heat, vibration, mechanical impact and thermal shocks. It also applies to the bonding of metals, alloy, ceramics, glass and transparent compound. |
| Features | It is transparent thick liquid. It cures within 55 seconds to 5minutes when exposed to 1KW UV light with its wavelength from 360 to 400 nm. 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 shine it with UV light. You.ll get long term durability and resistance to moisture, chemicals, oils, and temperature extremes. Non-toxic after it cures and it is upto the RoHS standard. Being stable, its storage time is one year. The main technical parameters are as follows: Heat resistance scope：- 70 °C—+ 350°C weather resistant(non yellowing when exposed to 300°C for 1hour, 250°C for 8 hours 200°C, 10000hours) , ; tensile strength:48Mpa compression strength: 223Mpa bending strength:103.6Mpa impact toughness: 15KJ/m*m shear strength: 28.8 MPa （25℃） 15.4 MPa 200℃ volume resistance: 1.7×1015Ω.cm sheet resistance 2.5×1015Ω voltage withstand 28-35.5kV/mm hardness shore D 80 dielectric coefficient:4.1 |
| 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. 2. Spray the adhesive on the substrates, put them together and apply some strength on them, expose it to 1000W UV light(360-400nm) 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. 3. It can be stored at well-ventilated places with low temperature, and keep them away from fire. Cover the lip after using it. |
