The image showcases three products from THAL Technologies, based in the Netherlands: a sealant tube in a caulk gun labeled "G270 Graphene," a small plastic jar labeled "G330 Graphene," and another sealant tube with a nozzle. A blue tool with teeth is also visible, ideal for applying thermal interface material.
A blue circle is filled with evenly spaced horizontal black lines, creating a striped pattern reminiscent of LED modules. The lines make the blue color appear as alternating light and dark blue horizontal stripes within the circle against a white background.

G320 – Glue

Heat-conducting adhesive with Graphene filler

G320 is a one-component epoxy featuring  high thermal conductivity and adhesive strength. Graphene, acting as the heat carrier, provides remarkable stability to the material. G320 demonstrates effective adhesive strength, not only with metallic but also with plastic materials.
