Composition of UV ink and its role in ink 

Reactive diluent (also known as diluent monomer): is a smaller molecular weight (low molecular weight) chemicals, it can reduce the viscosity of the dispersing of pigment and resin diluted, decided to ink surface properties, such as viscosity, hardness, softness. It does not evaporate, and is involved in the UV resin curing crosslinking reaction. 

The additives include: Paints, lubricants, thickening agent, filler, accelerator, it affects the color of the ink, ink layer thickness and curing speed, printability and ink weather resistance. 

The light solid resin: it is the main part of UV ink film, the binder of UV ink, ink gloss, adhesion UV. Different ink to the substrate of different materials with different resin. 

The initiator: it is chemical crosslinking reaction excitation. In the photochemical reaction, the initiator 

After optical excitation photon absorption becomes very excited, to produce free radicals, the energy is transferred to the other photosensitive polymer, the chain reaction, the single molecular matter, additive, light solid resin combined, form a reticular structure, and ink conjunctival firmly attached on the substrate.
