Diamond Dotted Paper which coating and baking modified epoxy resin rhombic on the electrical insulation paper is widely used in oil-immersed transformers, reactors,and turn insulation between layers.

During using, the coating layer in the process of coil drying and at a certain temperature, it will began melt and resulting in adhesion. With the temperature rises again the solidification , and the adjacent layers of the winding reliably bonded into a fixed unit. The bonding strength of the epoxy resin is sufficient to prevent the displacement of the various layers of the winding in the short circuit, so as to ensure the long-term mechanical and electrical properties of the insulation structure.
