Applications

• Candles, Wax & Soap: Perfect for intricate 3D pillar candles, highly detailed soap bars, and decorative wax melts.

• Food & Baking: Great for custom chocolate molds, hard candies, sugar crafts, and cake decorations.

• Art & Construction Castings: Highly compatible with Epoxy/UV resins, Jesmonite, concrete, plaster, gypsum, and polyurethane.

• Prototyping & Industrial: Excellent for replicating 3D-printed masters, rapid prototyping, and industrial tire or rubber patterns.

Platinum-cure silicones are highly sensitive and will fail to cure (remain sticky) if they come into contact with certain materials. 

Avoid contact with:

• Sulfur-based clays (use plastiline/wax-based clays instead)

• Tin-cure silicones or tools contaminated with them

• Latex gloves/rubber bands (always use Nitrile gloves)

• Certain 3D-printing resins, sulfur-containing pigments, and heavy metals

Always perform a small patch-test on a new master model before pouring your full mold.
