Instant adhesives cure very quickly when confined between surfaces. Surface humidity on the substrates triggers the cure reaction which moves from the substrate surfaces towards the middle of the adhesive joint. Instant Adhesives are chosen for bonding small parts to achieve extremely fast fixturing. Due to their limited gap filling capacity they require close fitting surfaces, Industrial Adhesive Manufacturer, Anaerobic Adhesive. The adhesion to most substrates is excellent and the bonding strength in shear and tensile mode is very good.
