Bostik Born2Bond RA-20 Retaining Compound

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-20 is a high viscosity, high strength anaerobic adhesive designed to retain cylindrical parts exposed to temperatures up to 230°C. Once cured the product prevents leakage and/or loosening of parts from vibration and shock.

Features:

• High strength
• High viscosity
• High power transmission
• Resistance to dynamic loads
• Vibration resistant
• Corrosion prevention
• Recommended for gaps up to 0.2mm
• Single component
• Suitable for active and passive metals

Directions For Use:

• For best results, clean all surfaces (internal and external) with Born2Bond
• Pre-Bonding Cleaner and wait until fully evaporated.
• If the cure speed is too slow on inactive metals, use Born2BondTM Anaerobic Activator.
• For slip fitted parts, apply the adhesive around the pin and the inside of the collar and rotate during assembly to ensure fully coverage.
• For press fitted parts, apply adhesive fully to both surfaces and assemble at high pressure.
• For shrink fitted parts, the adhesive should be on the pin, the collar should be heated.
• Parts should be fixed until sufficient handling strength is achieved.

Applications:

• Gear manufacturing
• Machine engineering
• Bearing assembly
• Drive shafts
