Fillite resin filler powder for addition to resins at up to a maxium of 140% by weight. The majority of our casters use this product at 50% by weight. A grey and black flecked powder which will both lighten and pad out your resin making it go further. Its a fairly bulky filler powder and one of our biggest sellers.
Compatible with Polyester and Polyurethane Fast Cast, it may also be used in Gypsum Plasters such as Herculite 2 though for plasters we really recommend Vermiculite. It has not been tested in Epoxy, but we feel it would be compatible. Available in 1kg, 2kg, 5kg and 20kg bags.
