Surface Modification for Inorganic Materials
Before being introduced to organic resins, inorganic filler materials can be treated on their surfaces using one of two general techniques.
Wet Approach
A highly uniform and accurate surface treatment of the inorganic material can be achieved by combining a slurry of the inorganic materials with a diluted solution of the silane coupling agent.Dry Approach
In order to disseminate the silane coupling agent into the inorganic components, a high-shear, high-speed mixer is used. Typically, the silane is applied neatly or as a concentrated solution. The Dry Method is frequently chosen over the Wet Method for large-scale manufacturing because it can treat a lot of filler quickly and produces very little mixed waste, although it is more challenging to provide uniform treatment with this method.Supplementing Organic Materials
Although curing may be more challenging, adding silane to the organic resin is more frequently utilized in industries than methods for treating the surfaces of inorganic materials due to its superior process efficiency. There are two standard approaches.
