Brass Metal Powder
"Cold-Casting" is a term used to describe the process of mixing metal powder with a resin and applying the mixture into a mold. The finished casting gives the appearance and weight of solid metal. The metal cold-cast process is faster and much less expensive when compared with foundry casting of molten metal.
To make a metal cold-casting, metal powder is mixed into Smooth-Cast™ 325 Colormatch™ resin, duoMatrix™ NEO, or Matrix Dryve™ until the mixture is thick and creamy. The mixture is then "slush-cast" or brushed onto the mold surface until the material cures. The gel coat is then back-filled with straight resin, resin mixed with metal powder, resin mixed with lead shot or Foam-iT!™ rigid foam. Smooth-On offers metal powders that can be added to our liquid plastics to create cold cast metal castings.
Powders include bronze, brass, copper, aluminum and nickel/silver (for a pewter-like effect).
