EB curing is a form of radiation curing. It is a process of inducing specially prepared one hundred percent reactive liquid to be quickly converted into solid by taking electron beams as radiation sources. The principle is as follows: firstly, high-energy electrons interact with paint or ink molecules to decompose the paint or ink molecules into free radicals; then, the free radical reacts with the C ═ C double bond to form a propagating chain; finally, the chain-extending chain reacts with the rest of the components of the coating or ink, so that the cured coating is crosslinked and the crosslinking density is increased. Due to the high energy of the irradiated electrons, the above reaction is often accompanied by negative reactions such as molecular degradation and molecular ion rearrangement. The EB cured coating thus produces a greater degree of branching and a higher crosslink density.

EB curing requires dedicated curing equipment. The working principle is as follows: after the electrons are emitted from a group of linear cathode plates, the electrons are accelerated by a vertical uniform electric field, and curtain-shaped electron beams are obtained under an accelerator irradiation box. The acceleration voltage is not high (less than 500kV) because the irradiated article is closer to the electric field, but the power is higher because of the large output current. The linear cathode gun is far more compact than scanning type equipment, is easier to install on a production line and is easier to shield.
