BSI Insta-Flex CA Adhesive is a water-thin cyanoacrylate adhesive well suited for fishing line rigging applications, including bonding hollow Spectra to monofilament or fluorocarbon. Its thin consistency provides excellent penetration into line and serving materials, while its fast-curing formula dries in seconds for efficient rigging and splice work. Unlike more rigid CA adhesives, Insta-Flex is formulated to remain flexible after curing rather than becoming brittle. The cured adhesive remains clear and provides strong shock resistance, making it particularly useful for connections and rigging applications that may experience repeated movement or loading. Supplied in a 3/4-ounce bottle, Insta-Flex provides enough adhesive for hundreds of line splice serves depending on application. Beyond fishing-line rigging, its penetrating properties also make it suitable for absorbent materials, and BSI notes that the formula performs well when bonding anodized aluminum.
