Free Form® SCULPT is a two part sculpt-able epoxy clay that requires no firing and will self-cure in a short time to an extremely hard and durable state with virtually no shrinkage. SCULPT is 30% lighter than similar products and holds vertical surfaces better. Users can sculpt larger, stronger pieces with more control over weight distribution. Free Form® SCULPT has an ultra fine particle size that gives the user the ability to sculpt finer detail with better precision using tools or shaping by hand and does not contain crystalline silica (which is a known carcinogen). For added control use Free Form® Detailer.
