| 1. Introduction |
| |
In the outfit working process of automobile, it makes airtight & watertight in door trim sealing.
Butyl rubber is a main composition with good adhesion in black color.
Once applied, it shows semi-permanent adhesive strength. |

function |
synthetic rubber |
base polymer |
functional filler |
complement for fluidity |
impregnating resin |
adhesiveness |
softener |
control viscosity |
extra components |
stabilizer, anti aging agent |
|
|
|
| |
| 3. Characteristics |
|
| |
1) not be stiffened in boiling condition or room temperature, keeping semi permanent adhesion. |
| |
2) not flow out of adhesive due to no fluidity of glue, maintaining stable quality of goods. |
| |
3) not contain hazardous materials, and safe to human body. |
| |
4) good in storage & stable preservation due to physical stability. |
|
| |
| 4. Application |
|
| |
necessary for process equipment because it’s provided in roll type of tape. |
| |
1) bond door access hole cover |
| |
2) apply to various decorative components in assembly. |
| |
 |
|
| |
| 5. how to use |
|
| |
1) remove the liner attached one side of product, and apply to preferred area, and cut away after application of necessary
length. |
| |
2) not integral dryness, if inevitably need to heat the material, be referred that thermal resistance is 180℃×20min. |
|
| |
| 6. Product Standard |
|
| |
Standard size is 3.5T×7m/m×20M ROLL but other sizes are available upon client’s request. |
|
| |
| 7. Product control |
|
| |
1) can be preserved for 3 months upon normal temperature. |
| |
2) cautious not to be deformed upon loading by the weight. |
| |
3) cautious not to be exposed on sunray or long term high temperature. |
|
