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.
URE-BOND™ II
URE-BOND™ II is a premium performance urethane adhesive compound that offers a strong flexible bond between many different surfaces. URE-BOND™ is ideal for adhering polyurethane rubber and other polymer products to many types of substrates (such as plaster, wood, cement, stone) and non-porous materials (such as glass, hard plastics and a variety of metals). URE-BOND™ II has also been used to repair torn polyurethane molds on a limited basis (with proper surface preparation). Working time is 5 minutes at room temperature (73° F / 23° C). Once mixed and applied, URE-BOND™ takes about 60 minutes to cure and yields a strong, flexible bond.
