Source: ConsumerReports.org Epoxies:
Epoxies are widely used in the two-component adhesives industry for many reasons; among them are outstanding adhesion to a wide variety of substrates, good strength, the ability to withstand harsh environmental conditions, and diversity of formulation potential.

New applications for adhesives are developed daily, as adhesives continue to replace mechanical bonding devices such as rivets, bolts, and welds due to improved performance, improved stress distribution, weight savings without strength reduction, noise and vibration reduction, improved aesthetics, and the increasing use of plastic substrates.

Measurement:
One of the best measures of flexibility and adhesion is peel strength. 20-25 pli.
Lap Shear Strength: 1000-2800 psi
Tensile Strength: 4000-9000 psi
Compression Strength: 15,000 psi

EP21TDCHT
Master Bond Inc., Hackensack, N.J. is pleased to announce the development of EP21TDCHT, a new two component epoxy adhesive with high peel and shear strength.
Resistant to vibration, impact, shock, and thermal cycling, 2-component EP21TDCHT bonds dissimilar substrates, including metals, glass, ceramics, rubbers, and plastics, with different coefficients of expansion. It cures at room temperatures and has service operating temperature range of -100 to +350¡F. With 70 shore D hardness and tensile strength over 3,500 psi, bonds resist water, oils, and organic solvents. Product exhibits tensile modulus of 175,000 psi.

J-B WELD:
Use J-B WELD as an adhesive, laminate, plug, filler, sealant, and electrical insulator.
Like metal, J-B WELD can be formed, drilled, ground, tapped, machined, filled, sanded, and painted. It stays pliable for about 30 minutes after mixing, sets in 4-6 hours, and cures fully in 15-24 hours. It's water-proof; petroleum-, chemical-, and acid-resistent; resists shock, vibration, and extreme temperature fluctuations, and withstands temperatures up to 500°.
