Retaining Compound 668 Series

Loctite 640470 is a green semi-solid retaining compound supplied in a 19g stick. It is designed for bonding cylindrical steel assemblies where a no-drip application is required. The methacrylate ester base develops a shear strength of 2,610 psi after full cure.

Gap Fill and Temperature Limits

The compound fills gaps up to .005 in and provides a working time of 10 minutes for assembly adjustments. It operates continuously between -65 Degrees F and 400 Degrees F, reaching full cure in 1 day. A primer is required on inactive surfaces to ensure reliable performance.

Stick Format and Clean-Up

The semi-solid stick format allows direct, controlled application without the mess of liquid anaerobic bottles. Clean-up is completed using solvent and a wire brush before the adhesive cures. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

Which container size should I choose for a small repair job?

The 19 g stick supplies .7 oz of semi‑solid compound, enough for several small‑gap assemblies without waste.

What does the 610 psi shear strength mean when the part is in service?

After full cure the bond resists 2,610 psi of shear load, so a properly prepared steel joint will hold typical shaft‑to‑hub stresses.

Does the methacrylate ester base require a primer on steel, and what gap does it fill?

Yes, primer is required on steel, and the compound fills gaps up to .005 in while curing in 10 minutes working time.
