A high load of filler will turn the resin into a putty consistency. This filler has very high quality consistency, low moisture content and due to these reasons, actually makes the finished casting less expensive in the long run than using less expensive similar fillers.
Quality control pays.
Always keep containers closed to avoid moisture contamination. Again, this is where good quality control saves through less rejects. We have tested many brands and types of fillers and we only accept the best. Cannot be painted. The density of the resin remains almost the same with the filler added.
