OC-800 is a thermally conductive phase change material having a softening temperature of 50-65℃. The liquid phase of the material can fill interface irregularities with much higher efficiency than traditional gap filler. On the other hand, it is a solid at room temperature and can be handled easily during installation.

OC-800 is RoHS compliant and halogen-free. It is naturally tacky and additional adhesive is generally not required.
