Graphene high-conductivity composite screen printing ink is a coating that uses graphene as the main conductive material and is combined with resins, solvents, dispersants, and other auxiliary materials through a specific preparation process. It is mainly used in screen printing processes and can print conductive patterns on a variety of substrates, including paper, plastic films, and metal foils.

Note: The above data are from a single measurement; results may vary between different batches. The viscosity of the slurry increases over time.

Viscosity Test Reference: Under the condition of ensuring uniform stirring of the sample, use rotor No. 4 at a speed of 12 rpm for testing (Rotational Viscometer: NDJ-5S).
