Kohesi Bond KB 1040 CTE-LO is an exclusive two component epoxy
system
suitable for bonding, sealing, coating and encapsulation applications. It
has
a favorable 10:1 (Part A: Part B) mix ratio by weight. Remarkably, it
offers
extremely low coefficient of thermal expansion (CTE) and is capable of
passing NASA low outgassing test. The optimal cure schedule is an
overnight room temperature set-up followed by a heat cure at 70°C –
90°C
for 3 – 5 hours. However, speedy cures are achievable with a straight
heat
cure as well at elevated temperatures.

KB 1040 CTE-LO can withstand extreme thermal environments down to
cryogenic temperatures. It offers an extensive serviceable temperature
range of 4K (-269.15°C) to +120°C. It is a phenomenal adhesive that
offers outstanding physical strength properties and dimensional stability.
KB 1040 CTE-LO adheres well to a wide variety of substrates including
metals, ceramics, most plastics and glass. In addition to superior
electrical
insulation and thermal conductivity, it also offers astounding chemical
resistance to a variety of fuels, oils and water. Part A has an off-white
color
and Part B has a clear color. Owing to its vacuum compatibility and
exorbitantly low CTE, KB 1040 CTE-LO is widely used in electronics,
aerospace, optical, semiconductor and various OEM applications.
