EP30P is a two-component epoxy that cures at room temperature with a mixed viscosity of 1,200 cps. Despite being an industrial-grade adhesive, EP30P is easy to apply and cure even when the materials being bonded have dissimilar substrates. EP37-3FLF is a two-part epoxy that forms a very flexible, high-strength bond that will withstand impacts, thermal cyclings and shocks without breaking.

Supreme 3HT-80 is a one-component epoxy that cures in 30 minutes at 175 degrees Fahrenheit and in 10 minutes at 250 degrees Fahrenheit. Supreme 3HT-80 is highly recommended for adhering heat-sensitive materials together, and it can withstand temperatures between minus 100 degrees Fahrenheit and 350 degrees Fahrenheit.

Another adhesive manufactured by Master Bond, EP21LVMed, is a two-part epoxy used for bonding and sealing in medical applications. It produces a very strong bond that withstands thermal cycling and has a resistance to a wide range of chemicals. EP21LVMed tolerates temperatures ranging from minus 65 degrees Fahrenheit to 250 degrees Fahrenheit.
