Anti Caking Agent Silicon Dioxide For Film Coating

What is film coating? And what is film coating technology?

Film coating is a type of common coatings. Nowadays, film coating technology is developed rapidly depends on the market's development.

Actually, using film coating on the goods is not so simple as you think. It is a special technology that is suitable to used in different surfaces of

different materials by powder state or by liquid state. Below are several steps to using film coating on the substrate.

1. Surface treatment: before using film coating on the substrate we should clean the substrate and start to preprocess the substrate.Through this

process, the dusty and other impurities on the coating's surface can be removed which can ensure the coating will be attached firmly to the substrate.

2. Painting: using inkjet tools, brushes, roller and other tools to paint the coating evenly on the substrate. Normally electrostatic spraying equipment will

be used for powder coating that will ionize the powder particles and adsorb it the  substrate firstly and raise the temperature to make the powder melt

curing.

3. Curing: making the coating be curing by raise the temperature or other ways. For liquid coating,drying process is used commonly. But for powder coating,

this might be related to curing process which is raising the temperature to melt the powder and form a hard outer.

4. Quality control: quality test must be acted in the very last. This can make sure the coating is arriving the expected quality standards include appearance,

thickness, adhesion property, anti-corrosive property and weather fatness.

How can Silica Matting Agent work in film coating?

1. Anti-caking: adding silica Matting Agent into film coating can help to decrease the situation of adhesion between powder particles. Making the coating disperse

evenly which is help to improve the products' final quality.

2. Enhancing flow ability: adding silica matting agent can enhance the flow ability of coating with silica's specific properties including  excellent flowing ability and

disperation ability.

3. Control release rate: By adjusting the amount of silica added, the thickness and porosity of the coating layer can be affected, and the release rate of the drug can

be regulated to meet the release characteristics of different drugs.

4. Improve stability: Silica itself is a chemically inert substance and does not easily react with most drugs. Therefore, it helps protect the drug from environmental factors

such as humidity and temperature, thereby extending the shelf life of the drug.

5. Improve appearance: Good anti-caking properties ensure the flatness and smoothness of the coating layer and improve the overall appearance of the drug, which has

a positive impact on consumer acceptance and brand image.

In short, as an effective anti-caking agent, silica plays an indispensable role in the film coating process. Its application not only improves the physical properties of the drug,

but also makes an important contribution to improving the safety and effectiveness of the drug.

Film coating with silica matting agent is used in various industries.

- Automotive Area-  film coating can be used in inner of the car to provide protection and specific properties like scratches resistance.

- Furnitures Production- using film coating in furnitures can enhance their durability, beauty and specific properties like water resistance and antibacterial ability.

- Electric Products- using film coating in electric products can protect the circuit board and its case from effects caused by bad environment.

- Industrial Area- film coating can be used in windows or doors that provides heat preservation, sound insulation, UV protection and other functions.
