I was asked to come up with an alternative to traditional sand fillers for resin flooring applications. The main focus was to remove the risk of silica, but other parameters like hardness and chemical inertness are also important.
Below is an introduction video that discusses the requirements and why this particular problem is important for our industry as a whole.
The second video I shot shows the repair and discusses the potential of the silica-free product, including how else we could use it.
So what did you think about a silica-free filler blend? Would you substitute the current fillers you use for epoxy resin flooring applications if such a product was available?
