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.
Ecoflex™ 00-50
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing, or you can choose to mix and dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
