Dynamar Polyetherdiamine HC 1101 is a linear polyether diprimary amine which contains tetramethylene oxide(-C4H80-) as the principal recurring unit and has a molecular weight of approximately 10,000.
HC 1101 is characterized as follows.
- Primary amine end group functionally of 2
- High molecular weight
- Low toxicity
HC 1101 can be utilized as the flexible reactive segment in block-type copolymers containing both flexible and rigid segments.
It may be readily converted into very tough cured elastomers, for instance, by reaction with epoxy resins having an oxirane equivalence greater than one.
The reaction mixtures are characteristically liquids which can be poured, cast or molded and subsequently cured at room temperature, or more rapidly at elevated temperatures. |
