Master Bond’s New 2K Epoxy System Features Low Coefficient of Thermal Expansion
Master Bond EP42HT-3AO is a two component, moderate viscosity epoxy system with good flow properties.
Product Properties
It is ideal for small to moderate size encapsulating, potting and casting applications.
It is also effective in bonding fragile components requiring a low coefficient of thermal expansion.
EP42HT-3AO is designed to optimize heat dissipation properties, improve the quality and reliability of electronic devices subjected to thermo-mechanical stresses.
Some more Features
This compound combines a low CTE of 13-16x10-6 in/in/°C with a high glass transition temperature (Tg) of 140-150°C.
It has a thermal conductivity of 11-12 BTU•in/ft²•hr•°F [1.59-1.73 W/(m•K)].
It also exhibits low shrinkage upon curing, dimensional stability, and excellent structural strength.
EP42HT-3AO is a reliable electrical insulator with a volume resistivity of >1014 ohm-cm.
This system is serviceable from -100°F to +400°F.
This 100% reactive epoxy formulation has a non-critical 100 to 40 mix ratio by weight and a working life of 60-90 minutes after mixing for a 100 gram batch at 75°F. It has a recommended cure schedule of overnight at room temperature, followed by 2-3 hours at 150-200°F. EP42HT-3AO is available for use in ounce, ½ pint, pint, quart and gallon kit containers. Specialty packaging options in the form of pre-mixed and frozen syringes are also available. The specialty packaging allows for automated dispensing. The color of Part A is white and Part B is off-white.
