Bondloc B638 High Strength Retaining Compound 50ml
Bondloc B638 urethane acrylate adhesive for structural retention (30 N/mm² strength). Resists -55°C to 150°C. 50ml.
The Bondloc B638 High Strength Retaining Compound is an engineered adhesive designed for high-strength retention under cyclic loading conditions, ensuring longevity and performance without fatigue even under sustained stress. Ideal for structural components, it excels in applications involving cylindrical parts under dynamic load, keys, splines, and close-tolerance structural tubing.
This urethane acrylate-based resin (green in colour) offers rapid fixture speeds—5 minutes without activator, or under 5 minutes with activator—making it efficient for both maintenance and manufacturing applications. It delivers superior gap-filling capability (0.2mm) and maintains high static shear strength (30 N/mm²) once fully cured (24 hours).
With a temperature resistance range from -55°C to +150°C and a shelf life of 12 months, the B638 is both durable and reliable for industrial use. Its high viscosity (2500 cps) ensures ease of application, while a flash point above 85°C enhances safety during handling.
