Guidelines for making stable prepolymers from glycols:
|
prepolymer synthesis |
FX-9203 |
|
Isocyanate Type |
Only suitable for aliphatic isocyanates such as IPDI, HDI |
|
Parts of isocyanate |
>3-4% |
|
Catalyst for Prepolymer Reaction |
More stable without catalyst addition, but can also be added in small amounts |
|
Remark |
Suitable for prepolymer synthesis if the above conditions are met and guidelines are followed |
Thermal stability: prepolymer
