To end #HenkelWeek24, we are highlighting our #HenkelBestSeller – Ablestik 45W1/Catalyst 15 (Twin Pack)!
LOCTITE ABLESTIK 45 W1 is designed as a general purpose, adhesive and is particularly useful when bonding dissimilar substrates such as metal to plastic. It is designed for use where shock and peel resistance are desired. This product is recommended to be used with Catalyst 15.
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.

For the last #ProductSpotlight of #HenkelWeek24 we are focusing on BERGQUIST GAP PAD TGP 2400!
BERGQUIST GAP PAD TGP 2400 is a thermally conductive gap pad reinforced for easy handling and versatility. Providing a conductivity of 2.4 W/m-K, it efficiently transfers heat away from electronic components. The soft, elastic material conforms well to uneven surfaces, ensuring optimal thermal performance. This reinforced pad offers improved tear resistance, electrical isolation, and easier conversion for various applications. Well-suited for low-pressure applications, GAP PAD TGP 2400 comes with natural tack on both sides for simple assembly. Alternatively, a non-tack version is available for specific needs.
• Thermal Conductivity: 2.0 W/m-K • Low S-Class thermal resistance at very low pressures • Highly Conformable, low hardness • Designed for low-stress applications • Fiberglass reinforced for puncture, shear and tear resistance • Part Number – GP2500S20-0.160-02-0816
Our second #ProductSpotlight of #HenkelWeek24 is Ablestik 45 Clear/Catalyst 15 Clear (Twin Pack)
LOCTITE ABLESTIK 45 CLEAR is an unfilled epoxy adhesive which, by using catalyst 15 clear, can adjust the hardness from flexible to rigid. It has an easy mix ratio and bonds well to a wide variety of substrates. LOCTITE ABLESTIK 45 CLEAR is an unfilled, clear version of ABLESTIK 45
For the first #ProductSpotlight of #HenkelWeek2024 we are focusing on a thermally conductive encapsulant Stycast 2850FT!
Stycast 2850FT is a powerful encapsulation solution for thermally sensitive electronic components. Its exceptional thermal conductivity, superior shock resistance, and low CTE make it a top choice for ensuring optimal performance and longevity in various demanding applications.
Features and Benefits:
• General Purpose • Low Viscosity • Cures at Room Temperature • Good Machinability • Reduced Abrasion • Good Chemical Resistance
As mentioned on Friday we are kicking of #HenkelWeek2024 by putting a spotlight on their brand. From Adhesives and Encapsulants to their incredible Thermal range we always have a wide array of products available.

Electrically Conductive Adhesives – This is products such as Ablestik 60L, Ablestik 59c, Ablestik 56c and Ablestik 64c
Thermal Insulating Pads – This is products such as BERGQUIST GAP PAD TGP 1350, BERGQUIST GAP PAD TGP 1500R, BERGQUIST SIL PAD TSP 1600 and BERGQUIST SIL PAD TSP 1800ST
Thermally Conductive Encapsulants – This is products such as Stycast 2850MT, Stycast 2851FT, Stycast 2850FT & Catalyst 9 (1kg) and Stycast 2850FT
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!
Todays #ProductSpotlight focuses in on @ABS Technics’ SLF SA!
ABS-SLF-SA absorbers are a premium range of multi-layered material designed for exceptional microwave absorption. Their unique construction utilises precisely graded layers, that achieve a broadband reflectivity level exceeding -17dB at typical microwave frequencies. This translates to superior performance in attenuating unwanted signal reflections. This ABS product comes with a self adhesive layer.
