They can replace welding, save time and labor, and minimize distortion of thin panels for truck trailers, truck and bus bodies, and metal signs. Flex Welder FC is a fast-curing methacrylate for quickly and permanently assembling components that will flex or see shock, vibrations, or temperature variations up to 250°F. It can also form load-bearing bonds with high peel and shear strengths to nylons, composites, and other plastics. It needs little surface prep, fills gaps up to 3/8 in., has a 1:1 mix ratio, and can be applied manually or with pneumatic guns. Dev-Thane 5, a urethane-based adhesive, withstands temperatures to 180°F and forms tough, flexible bonds to metals, rubber, wood, foam, EPS, and ABS plastics. It is a primerless, two-part thixotropic paste with a 15-min pot life. It fixtures in about 15-min and fully cures in 3 hr at room temperature with 2.1-kpsi tensile and 400-pli tear strengths.
