Bondloc B638 High Strength Retainer, 10ml
Bondloc B638 retainer: high-strength adhesive for cylindrical parts. Resists fatigue, 30 N/mm² shear strength, -55°C to +150°C range.
The Bondloc B638 High Strength Retainer is an advanced urethane acrylate adhesive engineered to deliver superior retention strength under cyclic loading conditions. Its robust formulation ensures it maintains full strength without suffering fatigue even under prolonged stress, making it ideal for demanding structural applications.
Designed as a cylindrical parts supplement, this retainer is particularly suited for components under dynamic load, including keys, splines, and structural tubing with close-tolerance fits. Its quick fixture speed—under 5 minutes with activator and 5 minutes without—enhances productivity in assembly processes.
Key Features:
- High strength retention to prevent loosening under vibration or load.
- Excellent gap-filling capability (up to 0.2mm).
- Resilient across extreme temperatures (-55°C to +150°C).
- 30 N/mm² static shear strength once fully cured (24 hours).
Green-coloured for easy identification, this 10ml retainer offers a 12-month shelf life and meets rigorous performance standards, including a flash point above 85°C and a specific gravity of 1.08. Whether for industrial machinery, automotive assemblies, or precision engineering, the Bondloc B638 provides reliable, long-lasting bonding solutions.
