PRODUCT FEATURES AND TYPICAL USE
| ITEM NO | APPLICATION | PERFORMANCE
CHARACTERISTICS |
|
3102 General purpose |
For general electronic components potting and circuit board closure.
Room temperature can be cured, curing process exothermic temperature is low, low shrinkage |
Cured bright surface,
no cracking, moisture, insulation |
|
3105 Thermal type |
For high-power electronic components on the heat requirements of the
higher modules and circuit board potting protection. |
After the glue has cured heat dissipation,
and other properties, like 3102 |
|
3108 Transparent type |
Required for a transparent potting of electronic components and modules,
particularly for use in normal lighting requirements transparent potting |
Room temperature curing, curing after the high
transparency, other properties ,like 3102 |
|
3115 Heat-resistant type |
For general heat-resistant electronic components potting and circuit
board closed |
Mixing glue after a long time to use, heated at 80 ℃ in 2 to 3 hours full curing, and could be used at temperature 180 ℃ . |
| 3112
Flame retardant type |
For the requirements of flame retardant small and medium-sized electronic
devices potting and circuit board closed, such as capacitor enclosures, solid state relay potting, etc |
Otherproperties like 3102 |

- Mix the glue: the glue componentin the original packaging after the full mixing (no filler can not stir), the A and B components according to the provisions of the quality ratio of mixing (see the table above the mixing ratio), stir even after potting, The time available after mixing is shown in the table above. More than the available time, glue viscosity will be high, no longer suitable for perfusion. So each time with the amount of plastic should not be too much, otherwise it will cause a waste.
- Curing:Cure conditions See table above. Curing speed and temperature related, high temperature fast curing, winter temperature is low, curing time will be extended, a variety of plastic can be used curing curing method, at 80 ℃ under the conditions of curing 2 to 3 hours. After the hardening of the glue can be assembled, the test generally need to cure 24 to 48 hours after the. TYPICAL PROPERTIES
