TotalBoat Thixo Flex is a thickened flexible epoxy adhesive that makes it easier than ever to create permanent, waterproof structural bonds on boat parts and other items that are prone to flexing due to changes in temperature, humidity, and stress loads. Now with just ONE product, you can bond many different types of materials, including wood (either dry or damp), metals, fiberglass, glass, ceramics, and some plastics.Because Thixo Flex is more flexible than traditional epoxy resins and stronger than conventional 1-part urethane sealants it's ideal for building or repairing wooden boats that are prone to flexing. It's also easier to use than other 2-part thickened flexible epoxy adhesives because there's no measuring or mixing—resin and hardener are contained in an easy-to- use cartridge that fits any standard caulk gun (sold separately). Just attach a static mixing tip (included) and insert the cartridge into the caulk gun. When you squeeze the handle on the caulk gun, the two parts are mixed automatically and thoroughly. It's that easy to get the exact ratio and achieve a reliable cure every time.Two-part, non-sagging Thixo Flex is pre-thickened so it stays in place on vertical or overhead surfaces, yet is easy to spread. It can be used at temperatures as low as 40°F. At 72°F, Gel Time is 40 minutes, Working Time is 75 minutes, Sandable Cure Time is 7-10 hours, & Cure Time for High Loads is 24. Tensile Strength: 5,330 psi; Compressive Strength is 7,200 psi; Flexural Strength is 8,800 psi. Store the Thixo Flex cartridge at 60-90°F before use. TotalBoat Thixo Flex compares to West System G/Flex 655-8, but is a better value and easier to use because there's no messy measuring and mixing. Compared to typical one-part marine urethane adhesive sealants, Thixo Flex is more flexible, with improved long-term performance.
