Overview of Epoxy resins - Session 2

Epoxy; Resin; Thermoset; Polymer; Chemistry of Epoxy; Producer of Epoxy resins @EpoxyChannel
This series of videos will cover all aspects of epoxy resins from a technical point of view. It has been designed in eight modules including 1- Introduction to Epoxy Resin, 2- Key Features of Epoxy Resins, 3- Types of Epoxy Resins, 4- Curing of Epoxy Resins and Common Hardeners, 5-Epoxy Resin Modifications, 6-Epoxy Adhesives, 7-Epoxy in Coating Industry, 8-Epoxies in Composites.
This course is beneficial for Technical Sales Engineers, Sales Engineers, graduated and undergraduate students and all people involved in epoxy science and industry.
In this video/session, we will discuss history of epoxy resins, chemistry and terminology of epoxies, major producers of epoxy resins, advantages and disadvantages of epoxy systems.

Hi Sir, I would like to know that we produce epoxy resin or polyurethanes using polycondensation. But nylon 6,6 is also produced by polycondensation. So, why Nylon6,6 is thermoplastic and epoxy or polyurethane are thermosetting resins in liquid form.

Hello Pavan,
Let me explain it here: Polycondensation is a method of polymerization. It can be employed in synthesizing different polymers (e.g. containing different monomers). Simply, you have monomers, that react via polycondensation, and finally, a polymer is produced. However, this polymer can be either a thermoset or a thermoplastic. It means that if the synthesized polymer contains "unsaturated groups" like epoxies, C=C bonds, etc. it can further react. Here, we have thermosets as the polymeric chains can react further to produce a network. this is what we call crosslinking.
On the other hand, in thermoplastics, like Nylon 6,6, or PET, there is no unsaturated group available for further reaction. After the polymerization, the polymeric chains have no ability to be cross-linked. Here, we have long chains of connected monomers, but the chains are not connected.
