I think it's because this filler creates a smooth and strong bond. At least that's how West System describes the filler on their Filler Selection Guide page on their website. The link is here. www.westsystem.com/filler-selection-guide-2/ This is one of the reasons that I use West System epoxy. They help guide us about the best uses of the fillers. The chart is also printed on the filler containers when you buy the products.
Just wondering.... why is the silica a better choice for the fillets than the microfibre filler?
