Master Bond Polymer Adhesive EP51 is a fast "5 minute" curing two component epoxy adhesive for general purpose bonding formulated to cure at room temperature with a one-to-one mix ratio by weight or volume. It readily develops a high bonding strength of more than 2000 psi at room temperature. The bonding strength is relatively insensitive to cleaning procedures. Master Bond EP51 gels in about 5 minutes and cures within a few hours at ambient temperatures. Bonded parts can be safely handled within a half hour. It produces durable high strength and tough bonds which are remarkably resistant to thermal cycling and chemicals including water, oil and most organic solvents, over the exceptionally wide temperature range of 4K to +250°F. Adhesion to metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened adhesive is an electrical insulator. Master Bond EP51 adhesive is widely used in the electronic, electrical, computer, construction, metalworking, appliance, automotive and chemical industries. It is suggested that Master Bond EP51 be mixed in small quantities because of its fast gelling properties. It is highly recommended for production line assemblies and high speed bonding operations. EP51 is also an excellent adhesive/ sealant for cryogenic applications.
