Silicon Dioxide Powder For Backlit Film Printing

The relationship between silica Matting Agent and advertising film coating

Silica is a common chemical material that is used in various coatings. But natural silica can not be direct used in coating. 

It should be processed by technology. Normally synthetic silica is designed to used in coating. Cause natural silica's self 

features is changed by chemical process.Silica is often used in advertising film coating. It is added into coating to enhance 

surface properties of coating like smoothness, glossiness and ink adhesion property. When there is silica matting agent is 

existing in coating,it can prevent the ink from moisture to improve coating's printing quality. In addition, silica matting agent 

can also provide the property of adhesion-resistance in coating.With this property, the coating will not be caking or gluing 

together with others.

How can coating form as a transparent film?

Coating has four main materials include film-forming substance, pigment, additive and solvent. There are many types of coating 

in the market. Different coating types can  be classified by its production ways like coating methods, uses, coating film formation

methods, coating functions, object materials, drying methods, etc.

There are several important keys that affect the quality of the coating process include: coating quality, coating technology and 

equipment, and coating management.

Coating quality is the basic condition for forming a good outer coating film on an object.Coating technology and equipment are 

necessary conditions for giving full play to the quality of coatings. In addition to forming a good coating film,a large number of 

operations can reduce production costs and improve economic benefits.

Coating management is to ensure its technical implementation. Due to human and mechanical factors, it is easy to affect the 

stability of coating quality. Therefore, achieving standardized operations through coating management is an important condition 

for the coating process.

Although there are many coating methods, the coating process must be based on the type of coating, product requirements, 

materials, size and shape, etc., and the appropriate coating method must be selected.

Common drying methods include cooling drying and baking drying。

The coating is processed on the surface of the object through coating and then dries and hardens to form a so-called coating film.

Therefore, the storage period or usable time of the coating, the coating and drying processes are all closely related to the formation 

of the coating film.

Coating is composed of different elements. Therefore, the process of forming a coating film must go through several different 

processing methods and be completed after drying and hardening. Therefore, improper handling during the process, such as 

problems with the coating manufacturer itself, problems with the operation of the painting technicians, etc., are the main factors 

affecting the quality of the finished product. It must also rely on communication and cooperation between both parties to achieve 

the desired result.
