UV Curing Adhesives - Features and Properties

Get the competitive advantage you need. Master Bond's range of UV curable bonding, sealing, coating and potting & encapsulation compounds are single component and require no weighing or mixing prior to use. They are designed to speed productivity, eliminate waste, save energy, increase efficiency and improve reliability. Environmentally safe, they emit no volatiles or vapors during cure. They remain stable even after prolonged storage at room temperatures until exposed to a UV light source.This eliminates pot life problems. Remarkably fast curing with standard UV cure equipment, these systems will greatly enhance the speed of your operations. In most applications, cure speeds within a couple of seconds is common. This removes transient thermal exposures when adhering heat-sensitive substrates.
