Hardening Type Paste |
|
|
|
| |
| |
Hardening Type Paste : The function shall be activated by additive strength to material and binding of
Filler by cross linking between resins |
 |
Composed Elements of Hardening Type Paste |
|
| |
1. Resin : Major substance which affects to the type of work and speed of chemical reaction
(Applied temperature)
2. Hardening Substance : Cross linker which has solubility with resin and additives.
3. Filler : Metal substance (Ag, Cu) which affects to liquidity and heating expansibility, heating conductivity, and conductivity.
4. Solvent : Substance which maintains certain level of viscosity and shape according to the work method and time. |

Application Purpose of Hardening Type Paste |
|
| |
1. It shall be applied to unstable adhered substance by heat and limited sustainability.
2. Hardening Temperature
:
| Heating hardening type is in general being made of over 90% crossing linking for 10-60 minutes under the temperature of 150~200℃, and in particular case, it is possible to be hardening for 4-24 hours at normal temperature, and for 5 minutes at 250℃. |
3. Stability of Hardening Substance
:
| If hardening type paste is being made cross link over 90%, it has chemical resistance in organic liquid such as acetone, and is has heating stability against change and decomposition under 200℃. |
4. Paste Storing
:
| In general, the storing conditions for hardening type paste are in indoor refrigerator under the temperature of 5~10℃ without direct ray of light. In specific case, it could be stored in under below -10℃. It shall be stored in lower humidity without direct ray of light and radiant heat after effusion in the refrigerator. |
5. Cautions for Handling of Hardening Type Paste
| 1) |
After effusion of paste in refrigerator, it shall be leaved in normal indoor temperature for 2-3 hours without open. |
| |
| 2) |
Dew condensation shall be on the surface of Paste, and clean it with cloth and leave it in the normal temperature continuously. |
| |
| 3) |
Pleas open the Paste when the temperature is normal, and it shall be mixed for 30-60 minutes by the mixer. |
| |
| 4) |
After mixing work, please make sure the paste by before the work. (Please do not try to use the Paste which is lump together or not color evenly.) |
| |
| 5) |
The moisture could cause adhesive strength and pinhole, and thus attention on the paste temperature shall be made during rainy season or winter season. |
| |
| 6) |
In the event of increased level of paste viscosity, please use the diluent as designated. |
| 7) |
After the work has finished, the remained paste shall be managed separately, and please check the lump together when it shall be used again. (More than 2 time of usage shall be prohibited.) |
| |
| 8) |
Please clean the clothes and skin after the work, because it contains composition to be injected into the skin. |
