LOCTITE® GRADE AA
Features and Benefits
One of the original red, high-strength and low-viscosity, wicking-grade threadlocker formulation from the 1950s.
This green, high viscosity, high-strength anaerobic curing adhesive cures in the absence of air and presence of metal. It also fluoresces under UV light – great for quality control. The low viscosity of Grade AA also makes it ideal for sealing porosities in welds and metal castings. It is able to penetrate porosities and cracks by capillary action, filling voids as large as 0.127 mm (0.005").
