Description
UltraLok® 420GB is a two-part, fast-set structural methacrylate adhesive designed to bond metals, plastics, and composites with speed, strength, and simplicity. Competing directly with ASI MP 55420, 3M™ DP8405NS, and SciGrip SG5000-03, UltraLok 420GB delivers robust performance at a more economical price point.
Formulated with integrated glass beads to maintain bondline thickness and prevent over-clamping, this adhesive cures quickly at room temperature and requires no surface prep. Ideal for high-throughput assembly environments where repeatable strength and application speed are critical.
