Silane coupling treatment
Uniform surface treatment
Filler surface can be treated with a silane coupling agent at the monolayer level.
- ● Processing agent compatible with respective resin system is viable
- ● Reduced viscosity when mixed into resin
- ● Improved resin adhesion
Surface treatment improves compatibility with resin. This can reduce resin viscosity.
Difference in interface adhesion strength with resin caused
by presence/absence of the silane coupling treatment
Reduced resin viscosity as a result
of silane coupling treatment
Compatibility of the matrix with the silica surface and resin improves due to surface treatment.
Physical properties also improve accordingly.
● Silane coupling agent examples
