There are many kinds of ink additives, generally used are desiccant, thinner, anti-friction agent,

varnish, varnish, etc. Matting powder is generally used in uv inks on the market to achieve

the matting effect. The viscosity of uv ink has a great influence. The small holes on the surface

will absorb the solvent in the uv ink. When the solvent is absorbed into the matting powder,

the uv ink itself will become viscous and even agglomerate. As time goes by, the agglomeration

problem and the performance of the uv ink will be affected. The impact is growing. The special

wax powder for uv ink has no effect on the viscosity of uv ink; there is no foaming during

the stirring process, no defoaming agent is used at all, no need to go around in circles,

saving time and worry, and low risk. In addition, micronized wax is widely used in printing inks,

paints, and coatings due to its excellent performance, which can improve the surface's scratch

resistance, wear resistance, increase slip, improve anti-adhesiveness, and inhibit the gloss of

printing inks. To prevent pigment from settling, and to produce high-performance matt ink

with matt powder, it has become an indispensable and important additive in ink production.

Wax can effectively improve the surface properties of the coating film. It mainly includes

improving the smoothness and scratch resistance of the coating film, improving water

resistance, changing the rheological properties of the coating, and matting agents.

The specific functions and mechanisms are as follows:

1. Anti-slip, anti-adhesion, stain resistance, stickiness mainly refers to the adhesion between

the coating film and the surface of the coating and external substances, as well as the adhesion

of dust, dirt and pressure when exposed to the atmosphere. Wax additives can

effectively solve anti-blocking properties.

2. Anti-friction and anti-scratch. One of the factors to improve anti-friction and anti-scratch is

to reduce the friction coefficient of the coating surface, so that when the object touches the

coating surface, the sliding tendency is greater than the scratching tendency. The migration of

micro-wax powder to the surface of the coating film can greatly reduce the dynamic friction

coefficient of the coating film surface, and only a small amount is needed to achieve scratch

resistance. Adding wax micropowder into paint can greatly reduce the tendency of

the paint film to be polished by friction, while maintaining the durability of low gloss.
