Welcome to the sixth entry of The Dianhydrides Diaries, a bi-weekly series that will explore all the benefits of dianhydrides, along with the chemistry, applications, tips, and advice on how to gain a competitive edge with your next project. In earlier entries in this series, I described the high-temperature performance of epoxy formulations cured with dianhydrides. The high crosslink densities achieved from the use of dianhydrides lead to high glass-transition temperatures (Tg) and high [...]

Welcome to the fifth entry of The Dianhydrides Diaries, a bi-weekly series that will explore all the benefits of dianhydrides, along with the chemistry, applications, tips, and advice on how to gain a competitive edge with your next project. The core of any electrical wire is typically copper metal, which carries current for the larger device. However, another important but understated component is the wire insulation, which prevents the circuits from getting shorted or [...]

Welcome to the fourth entry of The Dianhydrides Diaries, a bi-weekly series that will explore all the benefits of dianhydrides, along with the chemistry, applications, tips, and advice on how to gain a competitive edge with your next project. You have heard this before. Dianhydride curing agents allow for very high glass transition temperatures (Tg) in epoxy resin formulations. A fair question would be how high, especially in comparison with other more commonly used [...]

Welcome to the third entry of The Dianhydrides Diaries, a bi-weekly series that will explore all the benefits of dianhydrides, along with the chemistry, applications, tips, and advice on how to gain a competitive edge with your next project. Epoxy resins cured with dianhydrides serve high-end polymer applications such as composites, adhesives, powder coatings and molding compounds. The performance of the overall system certainly relies upon the main ingredients in it, e.g., resins and [...]

Welcome to the second entry of The Dianhydrides Diaries, a bi-weekly series that will explore all the benefits of dianhydrides, along with the chemistry, applications, tips, and advice on how to gain a competitive edge with your next project. Have you ever seen images of space probes, satellites, or space stations and noticed that they are blanketed in what looks like gold foil? If so, did you know that this blanket owes its golden [...]
