Adding highly conductive carbon black to the epoxy resin during the solidification process, will the resin become conductive after solidification?

Usually to make conductive resin, conductive carbon black should be added in liquid state, and fully stirred to disperse the carbon black completely. If the dispersion effect is not ideal, some dispersants can be used to help disperse. If carbon black is added during the curing of the epoxy resin, it usually does not cause the resin to conduct electricity.

One is that conductive carbon black does not form a carrier, but only a layer attached to the surface, even if it conducts electricity, it will not be too uniform;

The second is that the conductive carbon black has not been dispersed, and cannot be compatible with the resin and solidified, so a good conductive path is not formed, so it is difficult to achieve a conductive effect.

Application requirements of environmentally friendly carbon black in epoxy floor coatings

Almost all epoxy floor coatings are two-component coatings, in which component A is mainly composed of epoxy resin, diluent, pigments and fillers and additives, component B is curing agent, and the main components are amine curing agent and accelerator , a small amount of epoxy resin and solvent.

In order to improve the compatibility of environmentally friendly carbon black and epoxy floor coatings, and reduce the impact of the addition of environmentally friendly carbon black on the performance of epoxy floor coatings, environmentally friendly carbon black should be selected from the same raw materials as epoxy floor coatings. The main components There are epoxy resin, diluent, dispersant and pigment powder (black is mainly carbon black).
