  • Impressive electrical insulator
  • Smooth and even flow
  • High strength properties
  • Very long working life

Product Description

Master Bond Supreme 46HT-2 is a two component epoxy system featuring an appealing array of high performance properties including superior temperature resistance, very good shear and peel strengths and stellar thermal cycling properties. It is especially useful as a structural bonding agent. It has a notable temperature resistance range of -100°F to +500°F.

Supreme 46HT-2 requires elevated temperature curing at a minimum of 250°F. The mix ratio is 100 to 35 by weight and is relatively forgiving. Supreme 46HT-2 bonds well to similar and dissimilar substrates including metals, ceramics, glass, composites and many plastics. It withstands exposure to a variety of chemicals including water, many acids, bases, solvents, fuels and oils. It is a top notch electrical insulator. As mentioned previously, it is well designed for bonding dissimilar substrates and withstands mechanical shocks and resists rigorous thermal cycling. The color of Part A is tan and the color of Part B is brown. Supreme 46HT-2 would be most commonly used in aerospace, electronic, specialty OEM applications where excellent adhesion, impressive temperature resistance and splendid thermal cycling capabilities are required.
