| Dynamar polyetherdiamine HC 1101 is a linear polyether diprimary amine which contains tetramethylene oxide as the principal recurring unit and has a molecular weight of approximately 10000. HC 1101 is characterized as follows - Primary amine and end group functionally of 2
- High molecular weight
- Low toxicity
HC 1101 can be utilized as the flexible reactive segment in block-type copolymer 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. High use levels will form elastomers characterized by the following properties: - High tensile strength and elongation
- Hydrolitic stability
- Adhesion properties similar to epoxy resins
- Excellent abrasion resistance
- High resilience and low heat build-up during dynamic use
- Wide range of available hardnesses
