Note: It is recommended that the filler is well, but not to intensly mixed to prevent the filler from being destroyed

The desired and possible quantity that can be added of these micro-grains varies from one material to the next and per each desired result.

With polyurethane, you can use the following mixture ratio Polyol: Iso: Fillite = 1: 1: 1 by weight.
At this mixture ratio, the weight of the product is 75% of what a cast without filler would have weighed.
