But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.
