  Guidelines for making stable prepolymers from glycols:

prepolymer synthesis

FX-9201

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
