BSI’s threadlockers are anaerobic adhesives that cure in the absence of air, which occurs as a threaded fastener is tightened. They prevent the loosening of fasteners due to shock or vibration. Full strength is reached in 1-3 hours. IC-Loc™ is not compatible with most plastics. For best results, all surfaces should be cleaned before the application of IC-Loc™. IC-Loc™ should be store at temperatures above 45ºF and less than 80ºF.
