Permabond HH167 1 x 75ml accordion

Product Name

Permabond HH167 1 x 75ml accordion

Brief Description

Permabond HH167 is a high viscosity, gap-filling silver paste, classified as an anaerobic acrylic adhesive. It is specifically designed for repairing metal machinery parts and for use as a retaining compound.

Popular Applications & Uses

- Repairing worn shafts- Fixing broken threads- Restoring damaged keyways and splines- Retaining components in slip-fitted assemblies- Retaining components in press-fitted assemblies- Retaining components in shrink-fitted assemblies- Electric motor retaining applications

Industries that Commonly Use It

- General Manufacturing- Metal Fabrication- Automotive Service/Repair- Engineering Services- Industrial Supply- Transportation/ Specialty Vehicle- Aerospace/Defense

Special and Unique Features

- High strength- Excellent chemical resistance- Excellent temperature resistance, with an operating range of -55°C to +150°C- Metallic (silver) appearance- Solvent-free formulation- Cures at room temperature- Prevents corrosion- Gap-filling capability up to 0.5 mm

Key Properties

- Chemical Composition: Anaerobic Acrylic (Methacrylate)- Viscosity: High, approximately 500,000 cPs at 2rpm and 90,000 cPs at 20rpm- Color: Silver- Cure Method: Anaerobic (cures between two metallic surfaces in the absence of air)- Cure Time: Fixture time can be as fast as 15 minutes on steel at 23°C, with full cure typically 24 hours- Temperature Resistance: -55°C to +150°C- Chemical Resistance: Good resistance to water, oils, fuels (petrol, JP4, JP5), refrigerants, brake fluid, and IMS

Surface Compatibility

Permabond HH167 is compatible with various metals, including: - Steel- Copper and its alloys (e.g., brass)- Iron (e.g., cast iron)- Stainless steel- Aluminum (including anodized)- Zinc- Titanium- Magnesium- Nickel- Chrome finishes- Cadmium finishesFor optimal results, surfaces should be clean, dry, grease-free, and abraded.

Known backups / known substitutes

- Loctite 660 is mentioned as a known alternative.- Permabond A905 or ASC10 activators can be used to accelerate cure speed, especially on inactive surfaces like zinc, aluminum, and stainless steel.

Comparison Note

Permabond HH167 is an anaerobic adhesive, which is ideal for applications involving closely-mating metallic components. Its cure speed can vary depending on the type of metal (faster on copper, slower on passivated surfaces like stainless steel) and temperature (higher temperatures reduce cure time). It offers a high-strength, gap-filling solution for metal repair and retention, providing an alternative to traditional fastening methods in certain applications.
