Permabond HM162 Anaerobic Retainer

Permabond® HM162 is a medium viscosity retaining compound that cures when confined between metal parts to form an extremely tough bond. It is best suited for cylindrical parts and where high temperature resistance is required. In the uncured, liquid state, the adhesive wets the metal surfaces, keying into all surface irregularities and fills the space between the mated parts.

Features & Benefits

• Rapid cure

• Full strength (M10 steel) @23°C 24 hours

Typical Performance of Cured Adhesive

• Torque strength (M10 steel ISO10964) Break 32 N·m 280 in.lb
• Prevail 57 N·m 510 in.lb
• Shear strength (steel collar & pin ISO10123) 30 MPa 4300 psi
• Coefficient of thermal expansion 90 x 10–6 mm/mm/°C
• Dielectric strength 11 kV/mm
• Thermal conductivity 0.19 W/(m.K)

Surface Preparation

• Though the anaerobic adhesives will tolerate a slight degree of surface contamination, best results are obtained on clean, dry and grease free surfaces. The use of a suitable solvent-based cleaner (such as acetone or isopropanol) is recommended.
• In general, roughened surfaces (~25μm) give higher bond strengths than polished or ground surfaces.
• To reduce the curing time, especially on inactive surfaces (such as zinc, aluminium and stainless steel), the use of Permabond A905 or ASC10 can be considered

Directions for Use

1. Apply a circumferential bead; preferentially to the female component.
2. Assemble with a twisting action.
3. For larger components use thixotropic products to prevent run off.
4. Take care to ensure adhesive does not enter ball races or other mechanisms
