Measuring the Toughness of Thermosets

October 2, 2023 By Jeffrey Gotro Leave a Comment

Guest post by Jeremy Pasatta, Advanced Polymer Coatings Now that we have looked at the theory of toughening thermosets with second phase tougheners along with the two most common tougheners (RLP and coreshell particles) let’s look at how we measure the toughness of thermosets.  There are several different methods to measure the toughness of thermosets, and the method that is ...

Toughening Thermosets with Coreshell Particles

September 18, 2023 By Jeffrey Gotro Leave a Comment

Guest post by Jeremy Pasatta, Advanced Polymer Coatings The previous two blog posts have looked at both the fundamentals of toughening thermosets as well as one of the most common technologies used to toughen thermosets – Reactive Liquid Polymers and CTBN.  In this blog post, we’ll look at toughening thermosets with coreshell particles. Coreshell particles are exactly as ... [Click to Continue...]

Toughening Thermosets with Reactive Liquid Polymers

September 5, 2023 By Jeffrey Gotro 1 Comment

Guest post by Jeremy Pasatta, Advanced Polymer Coatings In the previous blog post, we explored the reasons why thermosets benefit from the addition of second phase tougheners.  One of the most successful and widely used forms of second phase tougheners is Reactive Liquid Polymers, or RLP.  RLP can be any polymer that is low enough in molecular weight to be able to flow at room ...

The Need for Tougheners in Thermosets

August 21, 2023 By Jeffrey Gotro 2 Comments

Guest post by Jeremy Pasatta, Advanced Polymer Coatings Thermosets such as epoxies, vinyl esters, cyanate esters, and benzoxazines give excellent properties such as chemical and thermal resistance, dimensional stability, high modulus and good adhesion to a variety of substrates.  These properties are in part due to the crosslink density of the thermoset, where in general the ...

Polymer Innovation Blog

I’m Dr. Jeff Gotro and welcome to the Polymer Innovation Blog. Over the last 40 years I have been involved in polymer research, along with product and process development. I acquired invaluable experience working for IBM, AlliedSignal, Honeywell and Ablestik Labs (now Henkel). In this blog, I (along with some guest contributors) will share our experiences, tips, and “tricks of the trade” to get more out of your innovation efforts and discuss new trends and technical advances in the polymer industry.
