Adhesive locks/seals fasteners on food processing equipment

For use on threaded fasteners located on food- and beverage-processing equipment, Henkel Corporation has introduced Loctite 2046, a medium strength, removable two-part anaerobic threadlocker that fully complies with the U.S. Federal Food, Drug, and Cosmetic Act and with all applicable food additive regulations including 21 C.F.R. 175.300.

The threadlocker is a two-part, room temperature-curing anaerobic adhesive designed to lock and seal threaded fasteners, ensuring properly secured hardware and improved equipment reliability. Once cured, this adhesive prevents the growth of bacteria between a fastener’s threads. Uniquely, Loctite 2046 is also said to eliminate possible problems associated with adhesive migration and contamination by curing at the fillet where a small amount of adhesive is exposed to air.

High viscosity Loctite 2046 is suitable for use on both fine and coarse threads. As it withstands temperatures up to 400¬∞F and endures the rigors of daily wash-downs, this threadlocker can be used in industrial deep-frying applications.  Loctite 2046 requires no primer when used on stainless steel equipment and can be disassembled with standard hand tools.

The threadlocker can be used to prevent loosening of fluid filler valve head cover bolts; thread stripping; or fastener rusting, galling and seizing. The unique two-component system includes three mixing tips that ensure proper proportions and full-cure characteristics. Additional mixing tips are available in bags of 10.
