Chavant Le Beau Touche Plasteline Clay, Green - Sulfur-Free Non-Drying Modeling Clay, 2 lb

Le Beau Touche is Chavant's soft, sulfur-free plasteline: an oil and wax based modeling clay that never dries out or hardens. In a composites shop it is what you reach for to build a parting line on a two piece mold, dam the edge of a splash, fill an undercut or a gap on a plug, and run temporary fillets, then peel it off and use it again. Because it carries no sulfur it will not inhibit platinum cure silicone the way sulfur-based clays do, and it stays hand pliable at room temperature while holding the shape you press it into. Specs Type sulfur-free, non-drying oil and wax based plasteline (plastilina) Color green Consistency soft, high tack, Shore 17A Softening point 100 F (38 C). Above about 90 F (32 C) it turns very soft and sticky Melting point 180 F (82 C) Block size 2 lb (0.9 kg), roughly 5 x 2.5 x 2.5 in Silicone Chavant rates it silicone friendly. Avoid citrus (d-limonene) solvents where silicone will touch it Shop uses parting lines, dams, fillets, filling undercuts on plugs, pattern and sculpture work Shelf life 2 years unopened, stored at room temperature out of sunlight Shipping not DOT regulated Working with it Knead it warm in your hands, or warm the block gently, to soften it. Do not overheat it. Press parting lines and dams tight against the plug and trim a clean edge with a clay tool or a putty knife. Smooth with a rubber rib, a spreader or hand pressure. A light wipe of naphtha, clear mineral spirits or 99% isopropyl alcohol slicks the surface. Skip citrus solvents if silicone rubber is going over it. Put a release over the clay before resin, gel coat or rubber goes against it. US Composites notes mold release can be applied over the clay to release resins or rubber molding material, and PVA #10 or Partall #2 paste wax both do that job. Pull the clay when the job is done, clean residue with naphtha or 99% isopropyl alcohol, wrap it in plastic and reuse it. The clay is not self supporting for tall figurative work, so build over an armature there. It adheres to aluminum wire, foil, cardboard, foam and paper. Pair it with tooling gel coat and a fiberglass mold making kit when you are taking a mold off a finished plug. Note on heat: this is the original soft formula, so a hot shop or a summer delivery can leave a block soft and slumped. Let it come back to room temperature and it firms up again. Chavant makes a firmer HTR version for shops that run consistently above 90 F (32 C). Data sheets: Chavant Le Beau Touche Technical Bulletin · Chavant Sulfur-Free Clay SDS
