ISL serious threadlocking compounds are structural cyanoacrylates that offer the strength and durability of anaerobics, and the cure times of an instant adhesive. This chemistry is NOT a metal reactive system. Unlike anaerobics, these materials will perform well on platings, stainless steel, and even plastic fasteners without the use of surface activators. Use on any type of components, including metal, plated parts, plastic, wood, etc., for thread locking, sealing, joining, fastening and retaining. Will not craze most plastics. Non-surface sensitive. Can be pre-applied. Develops cure to handling 1-5 minutes; 80 percent of full strength in 15-30 minutes. Shelf life 1 yr. @70F Optimum store @40F. NOTE: ISL compounds are not recommended for applications involving constant immersion in water or constant exposure to temperatures over 180F High Strength Permanent, locking/sealing fasteners up to 1inch in diameter. Disassembly difficult Meets MIL-A-46050C, Type II, Class 2
