Also, functional fillers like ATH (aluminum trihydrate) or MDH (magnesium hydroxide). For this purpose, the mineral surface of the filler or pigment must be chemically modified in order to adapt it to the respective resin it will be incorporated in.
For a high quality surface modification, functional organosilanes and silane oligomers are used. They chemically bond to the inorganic surface while the right choice of functionality of the silane result in:
- Reduced viscosity
- Better adhesion
- Higher degree of filling of the filled compound
