Loxeal 82-21 Retaining Compound Fast Cure Anaerobic Adhesive 50ml
Loxeal 82-21 is a fast curing, high strength anaerobic retaining compound for close-fitting cylindrical parts – shafts, bushes, pulleys and rotors. Its low viscosity flows into precise fits, reaching handling strength in as little as 5–10 minutes, and cures to a tough bond with 17–22 N/mm² shear strength. The cured adhesive is highly resistant to heat, corrosion, vibration, water, gases, oils and hydrocarbons across a service range of -55°C to +150°C.
Why choose Loxeal 82-21?
- Fast fixture – handling strength in 5–10 minutes keeps jobs moving
- High strength bond for permanent retention of close-fitted parts
- Low viscosity penetrates precise cylindrical fits (up to 0.10 mm gap)
- High impact strength of 11–15 kJ/m² for parts under shock loading
- Fills the joint completely, preventing fretting corrosion
- Resists vibration and many chemicals from -55°C to +150°C
Typical applications
- Bonding pulleys, gears and rotors onto shafts
- Retaining bushes and bearings in precision housings
- Production assembly where fast fixture times are needed
How to use
- Clean and degrease both parts with Loxeal Cleaner 10 and allow to dry.
- Apply the adhesive so the bond gap is completely filled.
- Assemble the parts promptly, seating them fully, and hold for the fixture time.
- Allow to cure before loading. On passive surfaces or in cold conditions, pre-treat with Loxeal Activator 11 to accelerate curing.
Cure times at +25°C
- Handling strength: 5–10 minutes
- Functional strength: 1–3 hours
- Full cure: 3–6 hours (maximum properties develop over 24–36 hours)

Chemical resistance
Manufacturer ageing tests show excellent long-term resistance to refrigerants (Freon) at +25°C, excellent resistance to petrol out to 500 hours, and moderate resistance to motor and gearbox oils at +40°C over extended exposure.
Important notes
- High strength – intended as a permanent retaining bond.
- Formulated for metal substrates only – contact a technical service before use on other materials.
- The liquid adhesive can damage coatings, some plastics and elastomers, and may cause stress cracking in some thermoplastics.
- To disassemble, heat parts to +150°C/+250°C, use normal tools, then remove cured residue mechanically and clean with acetone.
- Store in a cool, dry place at no more than +25°C and do not return used product to the container.
