Quantum® 138 is a surface insensitive cyanoacrylate adhesive formulated to improve adhesion properties and fixture time as well as gap filling capabilities over conventional cyanoacrylate adhesives. This advanced formulation improves adhesion to wood, leather, ceramics, elastomers, and acidic surfaces such as freshly plated components. Quantum® 138 is a state-of-art single component, solventless, room temperature curing adhesives that polymerize rapidly when pressed into a thin film between parts. The presence of surface moisture commences the cure of the adhesive. Quantum® 138 will develop handling strength within seconds and full cure within a few hours.
