Product Description
Si-Tac™
Si-Tac™ is a two-part pourable liquid silicone adhesive that is applied to natural or synthetic fabric/clothing for the purpose of keeping sports or leisure wear in place during exercise. Garments will not shift or fall. Si-Tac™ can be mixed and applied by hand, but is also often meter mix dispensed and delivered to the garment surface at strategic points through a narrow static mixing tube before being quickly heat cured. Certified Skin Safe, cured rubber is soft, comfortable and flexes with every movement; never noticed by the wearer.
Si-Tac™ silicone performs over a wide temperature range, is very strong, sweat resistant and lasts through many laundering cycles.
Free Form™ SCULPT
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.
A mirror-like, gloss finish can be achieved by smoothing SCULPT with water before it cures.
