Description:

Bostik Born2BondTM Retaining anaerobic adhesives are a cost effective, adaptable alternative or addition to mechanical retaining processes. Capable of bonding all types of cylindrical assemblies, these single-component solutions also seal all metal joints to eliminate the risk of fretting corrosion. They achieve 100% surface-to-surface contact, producing a cohesive, durable connection capable of withstanding vibration, extreme temperatures and chemical substances.

RA-48 is a medium viscosity, high strength anaerobic adhesive designed to retain cylindrical parts. Once cured the product prevents leakage and/or loosening of parts from vibration and shock.

KEY FEATURES

• High strength
• Medium viscosity
• High power transmission
• Resistance to dynamic loads
• Recommended for gaps up to 0.15mm
• Vibration resistant
• Corrosion prevention
• Single component
• Suitable for active and passive metals

DIRECTIONS FOR USE

1. For best results, clean all surfaces (internal and external) with Born2BondTM Pre-Bonding Cleaner and wait until fully evaporated.
2. If the cure speed is too slow on inactive metals, use Born2BondTM Anaerobic Activator.
3. For slip fitted parts, apply the adhesive around the pin and the inside of the collar and rotate during assembly to ensure fully coverage.
4. For press fitted parts, apply adhesive fully to both surfaces and assemble at high pressure.
5. For shrink fitted parts, the adhesive should be on the pin, the collar should be heated.
6. Parts should be fixed until sufficient handling strength is achieved.

METHOD OF USE

Manual: Directly from the bottle with or without dispensing tips for more precise dispensing.

Semi-Automated: Use of pressure-time systems for accurate volume and larger series.

Full-Automated: fully automated robot or application lines

APPLICATIONS

• Gear manufacturing
• Machine engineering
• Bearing assembly
