The main components of UV glue ink are polymerizable prepolymer, nylon + PC bonding, and plastic materials, and the auxiliary components are coloring pigments, fillers, and so on.

The use of UV inks in offset printing can eliminate powder spraying and avoid the trouble of post-printing processing caused by powder spraying. UV ink can also prevent the occurrence of ink skinning, which solves the worries of the offset printing machine when it is shut down, and at the same time can obtain a higher ink curing speed. UV offset printing ink has the characteristics of bright colors and good abrasion resistance, so it is very suitable for packaging printing, book cover and record sleeve printing. UV offset printing ink curing has no penetration problem. The following UV adhesive ink manufacturer Moore will talk to you about the composition of UV adhesive ink.

UV glue ink

1. Polymeric prepolymer

Polymerizable prepolymer is an important component that determines the performance of UV varnish coatings, and is generally classified according to the skeleton structure. The skeleton structure affects the hardness, friction resistance, adhesion, light resistance, chemical resistance and water resistance of the coating.

A.P+R bonding, silica gel + plastic, silica gel + metal, bonding of silica gel to spray ink bond, etc.

b. Fast curing;

c low odor

d Environmental protection;

e Great operability

2. Photoinitiator

The function of the photoinitiator is to absorb the energy of ultraviolet light, generate free radicals, and cause the ink to polymerize. The choice of photoinitiator should follow the following principles:

a. High light absorption efficiency in the UV glue range;

b. Good relative stability;

d. Good compatibility with prepolymer and monomer;

e. Little smell;

f. Low cost.
