Medical Film Coating Chemical Material Silicon Dioxide

Why WF-125-W silica Matting Agent can be used in medical film coating?

Using WF-25-W silica matting agent into medical film coating is crucial to produce high quality film coating. Due to medical 

film coating's special usage standards. Coating's additive should be selected strictly. Usages of silica matting agent are

different depend on different usages of medical film coating.When medical film coating is used in X-ray film, it is requested to 

have strong X-ray radiation resistance. When medical film coating is used in drugs, it is requested to have food safety test.

Here, our WF-125-W silica matting agent is suitable to used in X-ray film coating cause its excellent properties. We are 

changing the silica's original properties to make it fit with X-ray film coating.

Is there any advantages of using WF-125-W silica matting agent into medical film coating?

* Chemical stability: WF-25-W silica matting agent is chemically inertness so it will not act with other materials in medical film 

coating. With this property, it can avoid many unessential problems that might occur during production eventhough in different

environment.

*  Flow ability and disperation ability: dry powder silica matting agent has excellent flow ability which is disperse evenly

on the surface of coating and will not create caking situation in coating.

* Optical ability:  WF-25-W silica matting agent is different with other silica matting agents which have strong UV radiation

resistance. Depending on this type silica matting agent's special usage, we enhance its optical feeling ability to make images

can preform clearly on the X-ray medical film.
