Technological breakthrough with Expand-A-Lock®

ND Industries®, an internationally known developer and supplier of high quality fastener coating products and services is pleased to announce the latest break-through in microencapsulated locking and sealing technology, Expand-A-Lock.

An ND® exclusive product, Expand-A-Lock is the most effective microencapsulated chemical locking technology available. It simultaneously locks, bonds and seals fasteners against all air and fluid leakage.

When Expand-A-Lock’s chemical locking agent is activated, it also expands volumetrically 20-50%, filling any gaps and voids within the fastener threads and creating a positive seal against air and most automotive fluids. Expand-A-Lock will even effectively fill gaps resulting from fastener deformation during welding or oversized fastener threads.

The seal created by Expand-A-Lock will remains effective even under extreme pressures over 10,000 PSI.

Upon fastener engagement, full cure is achieved in 24 hours at room temperature. As a locking agent, fully cured Expand-A-Lock creates a bond comparable in strength to most epoxy threadlockers. Fully cured, Expand-A-Lock’s locking and sealing power is unaffected by exposure to foreign substances, including: oil, gasoline, salt-spray, acids, solvents, water and more.

ND Industries provides many top quality fastening and assembly related products and services, specializing in threadlockers, sealants, anaerobics, lubricants, adhesives and more, to a wide variety of industries, including automotive, electronics, aerospace, marine, construction, and appliance.
