Guest Post by Jeremy Pasatta, Advanced Polymer Coatings One of the largest drivers of new product development for thermosets, and in particular epoxies, is sustainability, and the curing agents for epoxies are no exception.  Today there are a variety of biobased curing agents for epoxy resins, and perhaps the most widely known and utilized are the phenalkamine family of ...

Guest Post by Jeremy Pasatta, Advanced Polymer Coatings All the epoxy curing agents in the last set of blog posts (amines, mercaptans and anhydrides) required mixing of the epoxy with the curing agent just prior to curing and are therefore considered two component formulations.  The common element between all these curing agents is that they immediately start reacting with the ...

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 ...
