This time last year we bid farewell to our old website by it “glitching “transforming” into our new website. A year on since that faithful day a lot has changed.
From hundreds of new products arriving onsite, to our new RFQ system we’ve been constantly building and improving our site. While this is only a small milestone, there is a lot more to come over the coming months and we hope that our efforts are worthwhile as our site continues to grow in age!
Bergquist (From Henkel) are one of our key Thermal Management brands. Providing products spanning from Gap Pads & Sil Pads to Hi-Flow and Bond-Ply. Their products come in a multitude of thicknesses and dimensions allowing for them to excel as thermal solutions.
Today’s #TechnicalTips is from @Henkel, and it is all about Degassing Adhesive products.
Sometimes undesirable gasses get trapped when using polyurethane/epoxy materials. As such the process of degassing is needed to remove them. Check out the article here where you can find out about how the process works and more specifically the affect of not degassing adhesives.
Today’s #ProductSpotlight focuses on @ParkerChomerics Cho-Therm 62-15-0808-1671 (with PSA)!
Cho-Therm insulator pads are designed for use where thermal, dielectric and mechanical properties are needed at their highest level. With a solid history spanning multiple decades in varying situations, Cho-Therm is the go-to product for industrial, Aerospace and Military applications
Today we bring you a Technical Tips on how to measure resistance of materials.
There are two main methods used to calculate resistance of elastomeric materials, a pressure probe or a surface probe (in this case a CHO-PROBE). With the use of these probes different methods can be used to calculate the Volume resistivity,

Today’s #ProductSpotlight focuses on @ParkerChomerics Polastrip 07-0201-0158-77!
Polastrip is a type of sponge material capable of shielding against electromagnetic interference. Available in different sizes it can easily be used in many different situations. With less force being needed to compress the material it provides greater strength over traditional methods of solving EMI shielding.
Todays #ProductSpotlight focuses in on Loctite Ablestik 59c!
Loctite ABLESTIK 59C is a high-temperature, thixotropic adhesive designed for applications that need electrical conductivity and a minimal need for a high bond strength. This product can be used with a variety of catalysts.
Introducing Bergquist Gap Pad TGP 40000SF and Bergquist Gap Pad TGP 18000SF, the two newest silicone free gap pads from Henkel. These fantastic thermally conductive fillers excel with heat transfer thanks to their z-axis orientation which allows for heat to transfer effectively from component to heat spreader.
Due to the no-cure system these products have, it makes it simple to pick and place them allowing for them to be reworkable. On top of this, due to their non-silicone polymer binder there is very low amount of bleed/ outgas from these Gap Pads. With their elastomeric properties, both the 40000SF and 18000SF have a high temp reliability for a non-silicone gap pad.

Aerospace and Defence – embedded processors and satellite payloads
High thermal performance requirements
Optical transceivers, lasers and Satellite payloads
Thicker bondline requirements.
Where disassembly may occur
No post-processing is preferred – power modules using solders requiring reflow
Immersion cooling applications in datacentres

As we usher in a new month, it is time to announce last months #BestSeller. June’s Best selling product was @permabond’s TA4208.
Product info
Permabond TA4208 (50ml) is a 2-part, 1:1 toughened acrylic adhesive. It can be used to bond a wide variety of materials including metals, plastics, composites, ceramics, wood and other substrates. The adhesive can provide excellent shear strength on many substrates with little surface preparation.
Crystallisation is a process where organic compounds go from a liquid state to a solid crystalline structure. In some cases this prove to be an unwanted phenomenon. In the case of epoxy systems, the risk of crystallisation increases when stored at low temperatures. Crystallisation happens in a very random way and is therefore hard to predict. The process is ultimately dependent on the purity of the raw materials used in the polymer system. The lower the number of contaminants that are present in the system, the higher the risk of crystallisation.
However, the process of decrystallization is possible when necessary. To learn more take a look at the below PDF!
