| Epoxies are the most widely used
polymeric materials for adhesives, sealants, coatings, pottings and
encapsulations and impregnants. They are available in both one and two
component systems. Two part systems can be cured at either room temperature
or elevated temperature. One part systems must be cured at elevated
temperatures (typically 250 - 300°F). One part systems curable by
UV light are also available.
Epoxies offer unique versatility in application and
performance. Their most desirable properties include high bond strength
to a wide variety of different substrates, outstanding gap filling capabilities,
excellent electrical insulation, high chemical inertness and outstanding
resistance to shock and vibration. Special formulations are available
including systems with thermal conductivity (electrically insulating)
for heat dissipation, electrically conductive systems, systems for cryogenic
applications, as well as systems with high performance in the most hostile
environmental conditions. Viscosities and cure times can be tailored
to meet specific application requirements. |
