How to Apply and Troubleshoot B-Stage Film Epoxy Adhesives

Posted by Dan Griffin on Sep 8, 2023 11:44:42 AM

Resin Designs TechFilm is a product line consisting of high-performance, partially cured epoxy adhesive films. These specialized film adhesives are designed as alternatives to two-part liquid epoxies. Techfilm advantages include clean, precise bond thickness and borders, low and high-temperature resiliency, and harsh environmental conditions resistance. 

An important question arises: what makes these films different than opting for traditional adhesive coatings? Let's review the unique strengths of TechFilm adhesives and discuss how to best implement their unique application process.

One of the most common terms that you hear when discussing polymers used as adhesives and coatings is the “glass transition temperature” (often abbreviated Tg). This property is in fact one of the most critical to consider when choosing the correct material for your application. Since many of us never got further than high school physics and chemistry, this term can be a little confusing and deserves explanation.

A layman’s definition of the glass transition temperature of a polymer is the temperature at which an amorphous polymer moves from a hard or glassy state to a softer, often rubbery or viscous state.

Processing and Troubleshooting Epoxy Adhesives and Encapsulants

Posted by Resin Designs Editor on Apr 6, 2020 11:30:00 AM

Two-component epoxies are versatile, viable adhesives and encapsulants that have demonstrated their value in the manufacture of electronics, medical devices, aerospace components, and many others. They provide superb electrical and mechanical properties along with the ability to resist extreme environments such as high and low temperatures and chemical exposure.

As part of our commitment to industry and customer support, we believe that our experience with two-component epoxies can be of value to manufacturers faced with certain processing and troubleshooting issues. While far from a comprehensive guide, we present below two common issues experienced when working with epoxies, as well as some tips on how to fix them.

5 Important Reasons Why You Should be Mindful of Glass Transitions Temperatures When Selecting an Epoxy Adhesive

Posted by Resin Designs Editor on Nov 8, 2017 11:03:00 AM

Unlike thermoplastic alternatives such as hot melt adhesives, cured thermosetting epoxies will not re-flow or melt when heated. Instead, epoxies will undergo a transition from a hard-rigid state to a more pliable, rubbery state. The temperature range during which this transition takes place is known as the glass transition temperature, Tg.
