Dynasylan® for Mineral Filler Treatment

Inorganic minerals like kaolin, clay, talc, mica, or quartz are widely used as fillers in the thermoplastic or rubber composite industry. Also, functional fillers like ATH (aluminium 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.
