Activator for Fast, Reliable, Structural Bonding

501-E-REV-A activator, when pre-applied to metallic, plated, ceramic, or glass substrates including PCBs, rapidly cures Multi-Cure® 600 series and 800 series structural adhesives and thermal interface materials in gaps from less than 1 mil to 20 mils. Activator bonding increases efficiency, consistency, and reliability and provides broad tolerance of adhesive-to-activator ratios. Rapid, on-demand curing to fixture or handling strength allows in-line quality control and increased production throughput.
