../../URE-FIL%20Fillers
URE-FILtm Fillers
Smooth-On URE-FIL 3 fillers is inexpensive filler that disperses easily in most Smooth-On casting resins (such as Smooth-Cast 300 ultra-low viscosity casting resin). It can be added to these resins in different proportions to achieve a variety of working properties and effects. Castings made using this filler will be lighter in mass and often be easier to cut, sand, machine, and shape. URE-FIL 3 can be added to thicken resins for brush-on application. It is also an economical extender that will reduce the cost of each casting, depending on the amount of filler used.

UREFIL 3 is a ceramic filler that is white in color and will give castings a ceramic finish.

Directions For Use With A General Purpose Resin:

Application of a release agent is necessary to facilitate demold. Universal Mold Release from Smooth-On is recommended. URE-FIL fillers must be thoroughly dispersed in Part B to a uniform consistency before adding Part A. If using a general purpose casting resin like Smooth-Cast 300, a mixture of One Part A, One Part B and two parts filler by volume (1:1:2) yields a castable resin that cures at room temperature in about one hour. A mix ratio of one part A, one part B and four parts filler (1:1:4) yields a resin that has a paste-like consistency.
