Cold embedding plastics
Demotec 10
A triple-component plastic based on modified polyester resin. Due to the extremely low material shrinkage, fissure-free embedding bases can be achieved. The product also has a very high viscosity.
| Components | powder / syrup / liquid |
|---|---|
| Mixture proportions | 4:2:1 |
| Time to harden | approximately 10 minutes |
| Colour | white |
Demotec 15 Plus
A dual-component plastic based on modified polyester resin.
The number 1 product amongst rapid-hardening cold embedding materials.
By means of a special combination of materials and by using new substances
it has been possible to develop for the very first time a rapid-hardening embedding material
which does not shrink but expands during the process of polymerisation!
In this way ideal circumstances are provided to enable the fissure-free embedding of materialographical samples
even in difficult shapes.
| Components | powder / liquid |
|---|---|
| Mixture proportions | 2:1 |
| Time to harden | approximately 10 minutes |
| Colour | light blue |
Demotec 20
A dual-component plastic based on methyl methacrylite for transparent section embeddings. The opaque transparency achieved by means of air polymerisation can be improved to a clear as glass transparency when the hardening process is performed in a pressure chamber (approximately 2 bar pressure). Demotec 20 is ideally suited to target preparations.
| Components | powder / liquid |
|---|---|
| Mixture proportions | 2:1 (can be varied) |
| Time to harden | approximately 8 minutes |
| Colour | opaque-transparent to clear as glass transparency |
Demotec 30
A dual-component plastic based on methylmethacrylat for quick, trouble-free section embeddings. Extremely easy to use.
| Components | powder / liquid |
|---|---|
| Mixture proportions | 2:1 (can be varied) |
| Time to harden | approximately 6 minutes |
| Colour | green-transparent |
Demotec 35
A dual-component plastic with a filling compound based on methyl methacrylate for quick, extremely hard section embeddings. High resistance to friction and high innate hardness.
| Components | powder / liquid |
|---|---|
| Mixture proportions | 2:1 |
| Time to harden | approximately 6 minutes |
| Colour | optionally light-green or black |
Demotec 70
A dual-component plastic, electrically conductive and based on methyl methacrylate and conductive carbon. Especially suited for examinations in the REM electron microscope, in the microprobe and for electrolytic polishing.
| Components | powder / liquid |
|---|---|
| Mixture proportions | 2:1 |
| Time to harden | approximately 15 to 20 minutes |
| Colour | black |
Auxiliary materials and accessories
We recommend the following as useful auxiliary materials in dealing with the plastics mentioned above:
