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.
VytaFlex™ 60
Using Smooth-On’s exclusive “V-Polymer™” technology, VytaFlex™ urethane rubbers offer superior physical and performance properties for casting concrete. VytaFlex™ urethanes are available in 10A, 20A, 30A, 40A, 45A, 50A and 60A Shore hardness’s and feature convenient one-to-one by volume mix ratios.
Vacuum degassing is not necessary and VytaFlex™ rubbers cure with negligible shrinkage to a durable rubber that will last in production.
VytaFlex™ mold rubbers work especially well for casting pigmented / colored concrete. Molds made with VytaFlex™ Series urethanes will render accurate and uniform colored castings.
