Product Introduction
Designed for rapid fixture and high shear strength, this adhesive bonds ferrites to plated metals in demanding applications. It achieves functional strength within minutes when used with Activator 7649, providing reliable performance in electric motors, loudspeakers, and precision assemblies requiring immediate handling.
Product Special Attributes
Unique viscosity stability (15,000 cP after 180s) enables gap-filling up to 0.5 mm. Delivers 15.2 N/mm² shear strength on grit-blasted steel after 24 hours. Exceptional dielectric properties: volume resistivity 2×10¹³ Ω·cm and dielectric strength 30 kV/mm. Maintains 100% strength after 5,000 hours in motor oil at 87°C.
Application Scenarios
Critical in automotive speaker magnet assembly (ferrite-to-yoke bonding), brushless DC motor manufacturing (rotor lamination fixation), and high-end jewelry settings (gemstone-metal adhesion per Henkel industrial reports). Extensively used in consumer electronics for vibration-resistant component bonding.
