Guest Post by Jeremy Pasatta, Huntsman Corporation In the last three blog posts, we investigated the use of amines and mercaptans as curing agents for epoxy resins, and in general these curatives gave moderate properties through room temperature reactions.  But what if you needed higher chemical and thermal resistance than what was capable with an amine or mercaptan?  ...

Guest Post by Jeremy Pasatta, Huntsman Corporation In the last two blog posts we looked at amines as curing agents for epoxies, and one downside of amines is that they can take up to a couple of hours to cure at ambient temperature depending on the structure, with the fastest amines still only curing in 30 minutes to an hour.  What if you wanted to develop an adhesive or ...

Guest Post by Jeremy Pasatta, Huntsman Corporation In the Part 1 blog post on amine curing agents for epoxies, we reviewed in general how amines react with epoxies, how to formulate with amine curing agents, and some of the general structure-property relationships of amines.  In this post, we will take a closer look at these structure property relationships, and how amine ...

Guest Post by Jeremy Pasatta, Huntsman Corporation This is the first in a series of six guest posts by Jeremy Pasatta. Curing agents for epoxies are one of the most critical, and often overlooked, parts of a formulation.  The correct choice of curing agent can dramatically improve the properties of the formulation such as heat resistance and flexibility while also allowing ...
