Description

MAGNABOND A638 – High Strength Anaerobic Retaining Compound

MAGNABOND A638 is a high-strength anaerobic retaining compound developed for the permanent bonding and locking of cylindrical metal components. It is engineered for demanding industrial environments where joint reliability, vibration resistance and long-term retention strength are critical.

The product cures in the absence of air when confined between close-fitting metal surfaces, forming a tough, cross-linked polymer that secures assemblies and prevents loosening, micro-movement, and leakage under dynamic loads.

MAGNABOND A638 is optimized for gap filling up to 0.25 mm, making it highly effective for retaining bearings, bushings, sleeves, gears, pulleys, and shaft-to-hub assemblies. Its advanced formulation ensures robust curing on both active and passive metals, including steel, stainless steel, aluminum, and plated substrates.

Designed for production, maintenance, and repair operations, MAGNABOND A638 delivers consistent performance in high-stress mechanical assemblies, helping extend equipment life and reduce unplanned downtime.
