Loctite 268 is a high-strength anaerobic threadlocker supplied as a wax-like semi-solid in a self-feeding stick applicator. It develops cured properties in the absence of air when confined between close-fitting metal surfaces. It works on active metals such as brass and copper and on passive substrates such as stainless steel and plated surfaces, and is suited to applications where a liquid product would be too fluid to stay on the part, including overhead and vertical work.
| Technology acrylic; chemical type dimethacrylate ester; appearance red, wax consistency; form stick; positive fluorescence under UV light; one component, requires no mixing; cure anaerobic; application threadlocking; strength high. Solid semi-solid stick allows direct contact to a threaded part for even coverage and clean application with no drip | |
| Typical uncured properties | specific gravity @ 25 degC 1.03; unworked penetration ISO 2137 90 to 150 (1/10 mm). Cure rate depends on substrate and temperature; activator SF 7471 or SF 7649 may be used to speed cure on inactive metals or in large gaps. PDF file (TDS) attached. 19 g stick. |
