Two Part, Room Temperature Curing Epoxy Features Ultra Low Coefficient of Thermal Expansion
Two component, room temperature curing epoxy compound features an ultra low coefficient of thermal expansion.
Master Bond EP42HT-2LTE is often chosen for a variety of bonding, sealing,
coating and select casting applications in the electronic, aerospace, optical
and specialty OEM industries. This two component epoxy has a flowable paste
consistency that enables precise alignment with minimal fixturing. It cures at
room temperature or more quickly with the addition of heat.
This system is notable for having a low coefficient of thermal expansion of
9-12 x 10-6 in/in/°C. With a tensile lap shear strength of over 1,200
psi, it bonds well to a wide variety of similar and dissimilar substrates,
including metals, composites, ceramics, glass and many plastics. EP42HT-2LTE
features superior electrical insulation properties, chemical resistance and
dimensional stability over the wide service temperature range of -60°F to
+300°F. It also offers low linear (<0.01%) and volumetric (<0.1%)
shrinkage upon curing, which is useful for potting and encapsulation
applications.
Featuring a light cream color, EP42HT-2LTE is prepared using a non-critical
100 to 40 mix ratio by weight or a 100 to 50 mix ratio by volume. After mixing a
100 gram batch, its working life is 60-90 minute open time. This product is
available in standard packaging with sizes ranging from ½ pint to 5 gallon kits.
