Product Description

Master Bond Supreme 42HT-2 is a special two part epoxy system combining robust temperature and chemical resistance, along with very good toughness. Supreme 42HT-2 is easy to use with a forgiving mix ratio of 100 to 40 by weight or 100 to 50 by volume. This permits the system to be used with a gun dispenser. Supreme 42HT-2 is a lower exotherm type system with a longer working life. It cures in 48-72 hours at ambient temperatures and in 2-3 hours at 200°F. To obtain optimum properties, the recommended cure schedule is overnight at room temperature followed by 3-5 hours at 160-200°F.

Supreme 42HT-2 is 100% reactive and does not contain any solvents or diluents. It also has low shrinkage upon curing. This epoxy will bond well to a wide variety of substrates including metals, composites, ceramics, glass and many plastics. Its toughness allows it to be well suited for bonding dissimilar substrates and to withstand rigorous thermal cycling. The cured epoxy is a superb electrical insulator and Supreme 42HT-2 is a good choice for small to moderate sized potting applications.

Another positive characteristic is its resistance to a wide range of chemicals including many acids, bases, solvents, fuels and oils. Its service temperature range is an impressive -80°F to +425°F. The color of Part A is tan to brown and the color of Part B is amber. This multi-faceted system can be used in aerospace, electronic, optical and OEM industries, where this special product profile is advantageous.
