Hernon
Metal Cement (TM) 850
(Silver Paste)

Hernon Metal Cement #850 is a single component, silver color paste designed for quick repairing of worn machinery parts. The compound develops a high strength polymer with superior compression strength, excellent chemical and temperature resistance. The bonded assembly often doubles the strength of press fitted parts.

Repairs worn metal parts like bushings, shafts.

Repairs worn housings, end bells, salvages severely worn parts.

Repairs wallowed keyways in shaft and spline assemblies.

Refits worn couplings.

Refits loose screws, spun bearings.

Use on new installations to prevent backlash, wear.

On new installations, corrosion is minimized (no air pockets).

Special Physical Properties

* Superior Ultimate Compression Strength: greater than 46,000 psi.

* Shear Strength - 3,000 psi (steel), 600 psi on unetched aluminum.

Note. use of EF (TM) Primer 50 will significantly reduce cure time, but, may reduce ultimate strength. Gently heat the assembly so that the bondline is subjected to a temperature of 250* F for 30 minutes for full cure. Primer is recommended to restore cure speed when used at temperatures below 50*F, and when gaps exceed.010 inches, diametrically.
