Master Bond Supreme 45HTND is a two component epoxy system featuring an attractive blend of superior physical properties especially shear and peel strengths for high performance structural bonding applications. It has a fine temperature resistance range of -100°F to +450°F. It is 100% reactive and does not contain any solvents or diluents. Supreme 45HTND is primarily formulated to withstand rigorous thermal cycling, especially when bonding dissimilar substrates.
Supreme 45HTND requires elevated temperature curing at a minimum of 250°F. However, Supreme 45HTND has a paste viscosity that will not flow while being cured. The mix ratio is 100 to 30 by weight and is relatively forgiving. Supreme 45HTND bonds well to a wide variety of substrates including metals, ceramics, glass, composites and many plastics and rubber materials. It resists a wide variety of chemicals including water, fuels, oils as well as many acids, bases and solvents. It is a top level electrical insulating system. The color of Part A is black and Part B is brown, although other colors are available. It can be used in challenging electronic, specialty OEM and aerospace applications where the combination of properties mentioned above is needed.
